INTERNET ENGINEERING REPORTS ---------------------------- 1. The Boston IETF meeting, held July 12-17, was "well attended" in that there were over 680 meeting attendees. Special thanks go to Chuck Davin and Jeff Schiller of MIT, and John Curran of NEARnet for the amazing work they did hosting the meeting, providing the terminal room, and for organizing the social event, and to the Hyatt Regency Staff. As was the case in San Diego, this IETF meeting enjoyed some "firsts." This meeting broke the 600 attendee mark as there were over 680 attendees. Following up on their successful efforts in San Diego, Steve Casner, Steve Deering, and a host of others joinged together and provided both an audio AND video broadcast of the technical presentations and open plenaries. There were 92 sites receiving audio broadcasts, and 45 sites that also received the video broadcast. The receivers of the audio/video broadcasts were spread over 11 different countries! 2. The next IETF is scheduled for November 16-20, 1992 in Washington, DC. Our local host is U.S. Sprint. The Spring Cooper [Page 4] Internet Monthly Report July 1992 1993 IETF will be held in Columbus, Ohio, March 28th - April 2nd, hosted by OARnet and The Ohio State University. Details for the Washington D.C. IETF meeting will be provided in future Internet Monthly reports and announced to the IETF mailing list. 3. The IESG received 6 requests to consider the following Internet Drafts as a standards track items: a. IP over HIPPI The IESG be pubished as a Proposed Standard. This document is an independent submission to the IESG. b. The PPP OSI Network Layer Control Protocol (OSINLCP) be published as a Proposed Standard c. AppleTalk Control Protocol (ATCP) be publishged as a Proposed Standard d. Telnet Remote Flow Control Option be published as a Proposed Standard. e. A String Representation of Distinguished Names be published as a Proposed Standard. f. Definitions of Managed Objects for the Ethernet-like Interface Types be published as a Draft Standard. Last Call notifications were sent to the IETF list on these items. 4. The IESG made the following recommendations to the IAB during the month of July, 1992: a. The Internet Draft "BGP OSPF Interaction" be published as a Proposed Standard. This document is the product of the Border Gateway Protocol Working Group of the IETF. b. The Internet Draft "Privacy and Accuracy Issues in Network Information Center Databases" be published as a FYI Informational RFC. This document was prepared by the Network Cooper [Page 5] Internet Monthly Report July 1992 Information Services Infrastructure working group of the IETF at the request of the IESG. 5.

These include: (1) Updating the MIB Internet Draft; (2) Updating the configuration and usage document; (3) Implementing the MIB; (4) Getting the required changes officially placed in the DNS; (5) Bringing the gated version of IDPR in line with the protocol specification. We are working on tasks (2) and (4). At the July IETF, other members of the IDPR Working Group volunteered to work on tasks (1), (3), (4), and (5). We are still planning on an Internet pilot of IDPR for late summer or early fall. Those interested in obtaining a copy of the IDPR gated software, please contact Woody Woodburn (woody@sparta.com). TWBNet During July, we fielded a new WPS release (v11.3). Throughout the month, the network has been stable and working well with this new software. In addition to some bug fixes and some enhancements in measurement and reporting of Butterfly clock speeds, the monitoring and system, the following new features have been added: 1. RAM card support -- This provides support for: + Faster rebooting -- All of the WPSen in TWBNET will be, or have already been, upgraded to have a Multibus card cage and a 1.5MB battery-backed RAM card. This is enough memory to store all of the WPS application software plus the operating system Chrysalis plus several debugging tools and symbol tables, and still have lots of space left. By storing the software on the RAM card, the time needed to reboot the WPS drops by 80% -- from about 35 minutes to around 7 minutes. + Improved crash cause analysis -- When a WPS crashes, it will, if possible, write out "what was on the console screen" to Cooper [Page 10] Internet Monthly Report July 1992 a file on the RAM card. (Each crash writes to a different filename.) New monitoring and control commands have been developed to permit these files to be uploaded to the NOC for study, and to make it easy to selectively delete these files. + Retention of configuration and parameter information updates In previous versions of the software, there was no convenient way to save configuration or parameter changes and restore them after a complete reboot. In v11.3, the RAM card is used to save and restore configuration and parameter information, eliminating the need for frequent WPS config file change and distribution. 2. Large-WPS support An aspect of recent WPS upgrades is that the WPSen are being converted from 2-column Butterfly machines (which support 1-16 processors) to 4-column Butterfly machines (which can support 64 processors) to allow expansion in the number of gateways that can be attached from 7 (today) to 20 or so. This software release includes table size increases needed to support the larger number of gateways and the larger number of processor nodes. 3. Builtin (static) group address tables increased Previous releases have supported only three builtin groups, with at most 10 members each. Release 11.3 supports seven builtin groups, with at most 30 members each. A "builtin" or "static" group is a HAP multicast address whose member list is constant (they're specified in the WPS config file). Currently, builtin groups are used to support the Conferencing and SIMNET applications where multicasting of packets is valuable. The distinction between "builtin groups" and "dynamic groups" (which will be in a future release) is that dynamic group addresses are allocated and freed using HAP Setup Request commands, and members join and leave the group as they wish, whereas static groups map specific HAP addresses into a fixed membership list. 4. Better stream and priority datagram service Part of providing good service to stream and high-priority datagram traffic is making sure that a high priority packet gets sent reasonably quickly even if it arrives after a group of lower priority packets. This means that, even when there's Cooper [Page 11] Internet Monthly Report July 1992 no high priority traffic to send at all, the device driver output queues can't be allowed to fill up with too much lower priority traffic. In order to limit the maximum delay a late-arriving high priority packet would suffer, line rate sensing has been implemented in this release. The HAP interface measures the rate at which data is being transmitted and then limits the amount of data enqueued to keep the maximum delay below a preset threshold. (The threshold is an adjustable parameter, and is currently set for about 200 milliseconds.) Jil Westcott (westcott@BBN.COM) CERFNET ------- During July CERFnet made some changes to the management staff. Susie Arnold has elected to leave her full-time position with CERFnet as manager of operations and enginnering to pursue a new career in teaching. Susie will still be available over the network, however, at her CERFnet mailing address which is listed below. (once a network junkie, it's hard to stop!) Pushpendra Mohta will be assuming responsibilities for engineering and Dan Matzke will be the manager of NOC operations. Susan Calcari remains as manager of network information services. Contact info for any CERFnet staff: help@cerf.net; 800-876-2373; 619-455-3900. Push: pushp@cerf.net Dan: matzked@cerf.net Susan C: calcaris@cerf.net Susie A: susie@cerf.net Susie, we'll see you on the net. Susan Calcari ISI --- GIGABIT NETWORKING ATOMIC The ATOMIC project at USC/ISI installed its first Mosaic-based 3- by-3 mesh router board, measuring approximately 8 inches by 9 inches. This router may be configured as either a 6-by-6 perfect crossbar or a 12-by-12 blocking crossbar. Six ATOMIC LAN host interfaces were attached to that router. That configuration achieved a combined throughput of 1.3 Gb/s across the router, a figure approximately 1/3 of the expected 4 Gb/s capacity. We are unable to generate more than 1.3 Gb/s of host packet traffic currently and so cannot test this small-scale router to saturation. The full-scale ATOMIC router is a same-size board configured as a 16-by-16 perfect crossbar or 32-by-32 blocking crossbar. Samples exist. These are undergoing fabrication testing and as routers are expected to achieve 10 Gb/s.

Ann Westine Cooper (Cooper@ISI.EDU) MULTIMEDIA CONFERENCING At the July IETF in Boston, Internet teleconferencing continued to break new ground! This time, both packet audio AND video were "mediacast" to participants spanning 170 different hosts and 10 different countries (AU, CA, CH, FR, JP, NL, NO, SE, UK, US). The configuration supported widescale listening and viewing of not only the general sessions, but also working groups pertaining to Audio/Video Transport, Teleconferencing Architecture, and IP Multicast. The DARTnet served as the multicast backbone with tunnels branching out over T3 backbone, lightly-loaded T1's and Ethernets. We are now coordinating the construction of the MBONE, the multicast backbone, to expose IP multicasting to scaling problems of 1 to 2 orders of magnitude. Cooper [Page 16] Internet Monthly Report July 1992 In the AVT WG, Steve Casner presented and led discussion on the second iteration of a strawman for a real-time transport protocol. In the Telearch BOF, Eve Schooler gave a presentation about the Control Control Protocol (CCP) for flexible n-way session orchestration. The hope is that IETF efforts in these areas will lead to broader solutions for telecollaboration across the Internet. Working with students at USC, we integrated software decoding of the compressed video used in DARTnet experiments with packet reception and X-window display software. This enables a larger number of receivers to participate in DARTnet experiments without additional hardware cost, and it facilitates workstation-based personal conferencing by eliminating the need for a separate monitor on which to display video. The implementation of CCP underwent refinements and testing over DARTnet this month. Steve Casner, Eve Schooler (casner@ISI.EDU, schooler@ISI.EDU) JVNCNET ------- I. General information A.

Walt Prue (Prue@ISI.EDU) NEARNET (NEW ENGLAND ACADEMIC AND RESEARCH NETWORK) --------------------------------------------------- As of July 31, NEARnet has grown to 147 members. NEARnet (in cooperation with MIT) provided a 10Mb/s IR laser connection to the 24th Internet Engineering Task Force (IETF) held in Cambridge MA. This link was used to support terminal room traffic and multicast audio/video sessions. Dan Long, John Curran, and Steve Miller participated in numerous meetings in the operations area of the IETF. Jim Naro attended the FARNET K-12 workshop. The purpose of this meeting was to match up Internet access providers with the regional laboratory directors from the US Department of Education's Office of Educational Research and Improvement (OERI). On July 31, 1992, NEARnet held the third seminar of its 1992 Mini- Seminar Series. More than 80 participants attended the NEARnet Cooper [Page 19] Internet Monthly Report July 1992 User Services Seminar, which was held at the Newman Auditorium at Bolt Beranek and Newman Inc. (BBN) in Cambridge, Massachusetts. This session focused on expanding the users' knowledge about resources and information available on the Internet. The seminar began with an overview of information servers presented by Jim Naro, NEARnet's user services manager. A videotape of WAIS: the Wide Area Information Servers system developed by Thinking Machines Corporation was shown. Cyndi Mills, the NSF Network Service Center (NNSC) Manager, presented a talk on the Internet Resource Guide and Internet HyperCard Tour. David Hanson, Associate Director for Academic Computing at Colby College, discussed library access using the Internet HyperCard Tour and Gopher. James Warner, Jr., Director of Prospect Hill Innovation Center (PI-net), gave a presentation on the PI-net Network Navigator. Richard Harrison, of Harrison & Troxell, Incoporated, gave a presentation on the InterNavigator, which included a demonstration of Archie, CARL, and the UnCover[tm] database available via CARL. Corinne Carroll NNSC, UCAR/BOLT BERANEK and NEWMAN, INC. ---------------------------------------- Cyndi Mills and Charlotte Mooers participated in several user services working group sessions at the IETF in Cambridge, Massachusetts. Cyndi Mills gave a presentation on NNSC activities at the NEARnet Mini-Seminar entitled, "Expanding Users' Knowledge of Internet Resources". The NNSC Staff has sent requests to all of the Internet Resource Guide contributors to revise and update their entries. The NNSC continues to process these updates to the Guide. The NNSC is also actively seeking new entries for the Resource Guide. If you know of a resource that should be included, please send a message to "resource-guide@nnsc.nsf.net" and we will be happy to send instructions and a template to the address you suggest. Due to an article published in the fall issue of "Online Access", the NNSC Staff has processed hundreds of requests for information on connecting to the Internet and obtaining a copy of the Internet Resource Guide. Corinne Carroll Cooper [Page 20] Internet Monthly Report July 1992 NORTHWESTNET ------------ We are very pleased to announce the results of our competitive, national search for NorthWestNet's first Director of User Services.

Schele Gislason NSFNET/ANSNET BACKBONE ENGINEERING ---------------------------------- T3 Backbone Status ================== Traffic migration from the T1 to the T3 backbone is in its final stages, with only a few networks on T1 left to be cut over to T3. New software is being deployed on the T3 backbone nodes to further improve performance and stability. Load-related problems continue to occur on the T1 network's Routing Control Processors and are being addressed with software changes to improve RCP efficiency. Activities for the "Phase IV" upgrade of the T3 backbone are being planned including FDDI adapter upgrades and other changes that will support dismantling of the T1 backbone later this year. Cooper [Page 21] Internet Monthly Report July 1992 Traffic Migration and Statistics ================================ In July, 12,884,937,091 packets entered the T3 network, up 20% from June. 4,754,950,521 packets entered the T1 network, down 17.5% from June. The total for both networks (minus cross-network traffic) was 17,063,064,412, up 8.4% from June. 6130 networks are configured for the T1 backbone, and 5269 for the T3 backbone. Actual network announcements by mid-level peer routers to the T1 backbone are 4426 networks, and 3508 to the T3. It is interesting to note that 1246 of the configured T1 networks were never actually announced to the backbone during the month; and 882 of the configured T3 networks were never announced to the backbone. New software has been installed to track the number of announced networks over time. During July, NorthWestNet, Terrestrial Wideband (TWB) Net, Milnet and Minnesota Supercomputer Center (MSC) Net were cut over to the T3 backbone. The remainder of the networks for Sprint and International Connections Manager (ICM) were cut over in early August. Networks remaining to be cut over are: ESNet, Mexican Networks (at Boulder), EASINet, and CA*Net. The first two are expected in mid- August. The EASINet and CA*Net peers are currently only physically connected to the T1 backbone and will be moved to allow peering with the T3 backbone in early September. Improvements to the T3 Backbone =============================== New Software Build ================== Version 2.81.31 of the AIX software and microcode has recently been deployed on the T3 backbone nodes. This build includes several significant fixes to problems and improvements to performance. These include: a buffering change to increase performance for T3 to ethernet interface transfers, a fix to a condition that causes an ethernet interface to freeze, on-card support for additional ethernet MIB-II variables, changes to the T3 card microcode, and a fix to a bug in ICMP time-stamp processing (now resolves to the millisecond). Cooper [Page 22] Internet Monthly Report July 1992 T3 Routing Software Changes =========================== Numerous improvements have been made to the T3 routing daemon, rcp_routed. These are described in release notes available for anonymous ftp: ftp.ans.net:/pub/info/t3-rcp_routed/Release-Notes The most significant recent change provides a workaround for regionals that generate a default pointing at 140.222 and find their ENSS isolated from the rest of 140.222 T3 system due to loss of the ENSS link to the CNSS. Other changes include better handling of BGP external metrics, and various reliability and operational improvements. Routing stability measurements have been made over the last few months. This information, in addition to the detailed logs have helped identify routing disturbances, isolate problems involving connectivity loss (IS-IS adjacency loss or BGP disconnect) which should not have occurred, and correct the problems. This has resulted in a measurable improvement in BGP stability. FDDI Interface Upgrade Planned for August ========================================= We are planning to upgrade the existing FDDI interfaces deployed on several ENSS nodes to new RS960 technology based interface adapters. Due to the complexity of the May '92 T3 upgrade, and the need for operational stability, it was decided not to upgrade the older FDDI interfaces at the same time as the T3 network. Instead, it was decided to decouple the process of testing and deployment of the new T3 technology from the new FDDI technology. The FDDI interface that is installed at each T3 ENSS location will be upgraded from an earlier technology to the newer RS960 adapter technology in August '92. This will raise the peak throughput observed by end users well beyond the current 10-14Mbps that may be observed today. Our objective is to continue to incrementally improve performance while maintaining very high reliability. Once the new FDDI adapters are installed and operational at the existing nodes, we will explore installations at other ENSS nodes that do not yet support FDDI. Cooper [Page 23] Internet Monthly Report July 1992 New SNMP Daemon Installed ========================= A new release of the SNMP software on the T3 backbone was installed. With the deployment of build 2.81.31 and SNMP version 3.213, in and out octet counts are available for the T960 ethernet and T1 cards. The current MIB variable map for the ethernet, T1 and T3 interfaces supported by the RS6000 nodes is as follows. inU outU inNU outNU inOct outOct InErr OutErr ==================================================================== T960 Ethernet | U+B U+B 0 0 OK OK IN+OUT 0 | RS960 T3 | 0 0 IN OUT OK OK OK OK | ==================================================================== The pending operating system upgrade of the RS/6000 routers to AIX 3.2 will allow for more complete support of the appropriate MIBS for each adapter type. RS/960 Memory Parity Problem ============================ A manufacturing problem with memory chips on a small number of the RS960 T3 interface adapters has been identified and corrected. However to protect against recurrence or new introduction of memory problems, we are scheduling diagnostics to be run on some nodes along with other scheduled maintenance over the next few weeks. DSU Synchronization Problem =========================== A problem was observed in the first few weeks after the April-May deployment of RS/960 T3 cards and DSUs, where a T3 DSU would lose synchronization with its peer on nodes that connect to the Houston POP. This problem has not been reproducible in our test labs or in the T3 Research Network after extensive experimentation, nor has it occurred on production nodes since then. DSU PROM Upgrade ================ The firmware in the T3 Technologies DSUs will be upgraded to a new level, allowing extended remote monitoring capability. This upgrade will be performed in the late August timeframe with plenty of advanced notice. Cooper [Page 24] Internet Monthly Report July 1992 T1 ENSS Memory Upgrades ======================= Each of the T1 ENSS nodes on the T3 backbone were recently upgraded from 16MB -> 32MB of main memory to provide capacity for increased paging. T1 Backbone Status ================== A new rcp_routed release was deployed early in July which increased the BGP packet size to 4096. This was necessary to allow a full complement of networks to be announced from the backbone to regional peers (the same change was made to the T3 rcp_routed). Later in the month another new rcp_routed version was deployed which contained changes to support compression of the IS-IS protocol LSP. This is necessary to allow the T1 network to sustain the current limit of 2200 networks being announced in from external mid-level peers to a single NSS. NSS 11 at Houston exhibited some problems after the Milnet networks were cut over to the T3 backbone. Some mid-level peers announce all of the networks learned from the T3 backbone into the T1 backbone, and these are stored by the T1 node but are marked as unusable. This caused the Houston RCP to run out of memory. A change was made to the peer routers to prevent these networks from being announced to the T1 network, and a future release of the rcp_routed will include a change so that these routes are not stored. T3 Backbone Phase IV Planning ============================= Upgrades to the T3 backbone are being planned to support future performance and functional enhancements, and to allow the dismantling of the T1 backbone. The major features of this plan include: 1) T3 ENSS FDDI interface upgrades to new RS/960 card. 2) A T1 circuit will be installed at each T3 ENSS to allow a backup connection to a different CNSS. This will provide some redundancy in the case of T3 circuit or primary CNSS failure. 3) Network source/destination pair traffic statistics collection for the T3 nodes. This feature is provided on the T1 backbone Cooper [Page 25] Internet Monthly Report July 1992 currently. 4) Open Systems Interconnection/Connectionless Network Protocol (OSI/CLNP) support. This feature is provided on the T1 backbone currently. 5) Upgrade selected T3 ENSS ethernet interfaces to new RS/960 ethernet card. 6) Topology Changes: o Moving the Washington D.C. area CNSS to a new MCI POP for closer proximity to several ENSS locations. The tail circuits of the existing network attachments to this POP will be reduced to local access circuits only. o Deploy a new CNSS in Atlanta to reduce the GA Tech T3 tail to local access only, and provide expansion capability in the southeast. Mark Knopper (mak@merit.edu) Jordan Becker (becker@ans.net) NSFNET/INFORMATION SERVICES --------------------------- The total number of networks announced to the NSFNET infrastructures reached 6031 at the close of July, with 4950 of these nets also announced to the T3 backbone. Estonia and Thailand are the newest foreign locations with networks announced to the NSFNET; 2133 networks of the total represent foreign network announcements. Merit announced WAIS and Gopher servers in July for the nic.merit.edu information server. This server has archives on the Internet, NSFNET, and MichNet. Currently, there are six Merit WAIS databases with more planned for the near future: nsfnet-rfcs.src The Internet Request for Comments and Internet Draft documents. internet-standards.src The sub-series of RFCs which document Internet Standards. internet-intros.src Introductory material on the Internet. merit-archive-mac.src Index for mac.archive.umich.edu Cooper [Page 26] Internet Monthly Report July 1992 merit-nsfnet-linkletter.src Articles from the Merit/NSFNET Link Letter, indexed by article. michnet-news.src Articles from the MichNet News, indexed by article. WAIS clients for the Macintosh and UNIX machines are available for anonymous ftp from ftp.oit.unc.edu in the pub/wais directory; WAIS software for VMS, DOS, and MS-Windows is at the same FTP site in the pub/wais/UNC directory. The source files specifying server locations and available databases are obtained from the "Directory of Servers" on the WAIS server at think.com. Every WAIS client has the source file which will connect to the Directory of Servers, allowing for access to the Merit sources as well as hundreds of others. The Merit Gopher server allows for anonymous ftp access to the wide array of network information on nic.merit.edu. Recent information resources to help the network novice become familiar with the Internet, including its associated networks, resources, and protocols may be selected from the "Recommended New-User Reading List." Legislative activity surrounding the High Performance Computing Act of 1991 and the Information Infrastructure and Technology Act of 1992 may be explored in "NREN (National Research and Education Network) Information." "National Science Foundation Information" includes the NSFNET backbone Services Acceptable Use Policy, as well as current NSF proposals for the Interim Interagency NREN. Connections to other information servers will also be possible. Client software to access the Merit Gopher server on port 70 of nic.merit.edu is available from boombox.micro.umn.edu. Access is possible through some other gopher servers. Future plans include the implementation of a vt100 telnet interface for the Merit Gopher. New directories on the nic.merit.edu host include /nsfnet/engineering.report, a repository for the monthly NSFNET/ANSNET Backbone Engineering reports, and /introducing.the.internet. Intended as a first stop for network novices, /introducing.the.internet includes several FYIs, Hedrick's "Introduction to the Internet Protocols" and Kehoe's "Zen and the Art of the Internet." This service is being implemented in conjunction with the IETF User-Doc Working Group. Eric Aupperle, President of Merit Network, Inc., Jim Williams, Merit Associate Director for National Networking, Ellen Hoffman, Manager of Merit Information Services and Elise Gerich, Internet Cooper [Page 27] Internet Monthly Report July 1992 Engineering participated in the FARNET IINREN Workshop held in Boston. Williams, Hoffman and Gerich joined Merit/NSFNET project colleagues Pat Smith and Chris Weider of Information Services, Mark Knopper, Manager of Merit Internet Engineering, Sheri Repucci and Sue Hares of Internet Engineering and Bill Norton of Network Management Systems in lively working groups at the Boston IETF. Among the IETF working group chairs and co-chairs are: Hoffman, User-Doc; Smith, NISI; Weider, DISI; and Hares, NOOP. Williams also attended the Communications Policy Forum in Washington, D.C. Steve Burdick, Information Services, attended the ACM/SIGGRAPH conference in Chicago. Merit/NSFNET Information Services will sponsor a one-and-a-half day seminar at the University of Michigan in Ann Arbor on October 19 & 20, 1992. "Making Your NSFNET Connection Count" brings together national experts to discuss the many aspects of the Internet and NSFNET and provides perspective on Internet tools, resources and applications. An optional three-hour hands-on tutorial to introduce participants to Internet tools such as electronic mail, telnet, ftp, Gopher, and WAIS will also be offered. For further information and a complete agenda, send an electronic message to seminar@merit.edu or telephone 1-800-66-MERIT, or (313) 936-3000. Jo Ann Ward (jward@merit.edu) PITTSBURGH SUPERCOMPUTER CENTER ------------------------------- Jamshid Mahdavi and Jon Boone helped the PSC join in the recent audio and video multicast of the plenary sessions of the IETF. We ran BBN's dvc for video and Van Jacobson's vat on a Sparcstation 1+. Besides viewing the multicast ourselves, we performed a local redistribution of the multicast. About 20 PSC staff members followed along with some of the sessions. Gene Hastings, Matt Mathis and Wendy Huntoon of the PSC attended the IETF conference. Gene chaired the Network Joint Management and Network Status Reports working groups. Matt chaired the BGP (Border Gateway Protocol) Deployment working group, which is fostering BGP in the Internet. The current global BGP topology was presented, including a description of the European "EBONE" which uses BGP as its interior routing protocol. Many router vendors described their BGP plans. There is a strong consensus that BGP is needed as soon as the vendors can support it. ANS publicly offered to help vendors with interoperability testing, this will be a big push for BGP. Cooper [Page 28] Internet Monthly Report July 1992 Matt, Gene and Wendy also attended a FARNET - NSF IIREN workshop to produce a technical commentary to the draft solicitation for the new NSFnet recompetition. Gene is a member of the organizing committee. The final document was unanimously supported by the NSF Supercomputing Center directors. A response to the NSF will be publicized and all attendees were urged to make their own responses. Attendees to the meeting included a broad spectrum of administrative, policy and technical people. Stephen Cunningham SDSC (SAN DIEGO SUPERCOMPUTER CENTER) ------------------------------------- SDSC Network Activities ======================= In support of the joint SDSC/ScrippsClinic/UCSD Med School SigGraph92 Showcase (an electron microscope at UCSD was controlled from the Showcase) we established a FDDI link to Scripps Clinic using loaned NSC equipment. This will be the beginning of the MAN ring linking sites here on the mesa. We also ran some end to end test between SDSC and ANL (as a stand- in for the SigGraph show floor) which showed disappointing performance. After some follow-up tests are run this month, we will post our results. We have taken our UltraNet hub out of service and are in the process of removing the various interface cards. As a replacement, we plan to use FDDI in the short term. Our permanent solution will be the NSC HiPPI P32 switch. For the CASA gigabit testbed project, we have ordered a HiPPI attached frame buffer and a HiPPI attached Sun workstation to run the HILDA network analysis system. We have also placed an order for a HiPPI link level tester to help maintain our fast growing HiPPI LAN. SDSC Applied Network Research Group =================================== The ANR group at SDSC has completed two papers in network analysis, and is currently in the middle of projects which will lead to several others. The first paper is a description of recent traffic characteristics of the T1 NSFNET backbone. We present this paper as a followup to Cooper [Page 29] Internet Monthly Report July 1992 the 1973 landmark paper by Kleinrock on ARPANET measurement and analysis. We include a description of the NSFNET environment, including available instrumentation and operationally available data sets. The measured quantities include: longterm growth in traffic volume, including attribution to domains and protocols; trend in average packet size on the network, both over long and medium term intervals; most popular sources, destinations, and site pairs; source-centric favoritism; international distribution of traffic; mean utilization statistics, both of the overall backbone as well as of specific links of interest; delay statstics; and, assessment of downtime for the last few years. The second paper is an exposition on measurement considerations for assessing unidirectional latencies. We actively evaluated single direction latencies to selected destinations of the Internet utilizing a variety of paths. Our objective was to demonstrate that round-trip latencies are an insufficient and sometimes misleading method to determine unidirectional delays. This claim has significant implications for today's high-speed, multi- application networking environments which often require predictability of precise delay. For example, designers of real- time applications who intend to deploy their products on the Internet, or some wide-area, high-speed, highly aggregated network, should be aware that across the periphery of such an environment, symmetric delay will serve unpredictably as a model of network performance. Another ANR project underway is an investigation of the delay, throughput and reliability characteristics of [transport layer] connections. This project will include a routing dynamics component to account for system routing dynamics. We have designed experiments to measure delay, delay variance, reliability and connection throughput for a variety of end-to-end configurations. An end goal is to mathematically parametrize these quantities in terms of some base network quantities, such as: number of ASs traversed; size (hops, delay, etc.) of transit AS; min, max, average data switching speeds; or average routing instabilities. The project objective is a better response to the questions: How does the Internet perform? Can we predict its performance based on path information? ANR is pursuing ongoing investigation into the visualization of network phenomenon and characteristics. Initially, we would like to focus on geographic representation of traffic flow between countries, for example the animation of selected frames to produce a visual time series of this data. Cooper [Page 30] Internet Monthly Report July 1992 Finally, we continue to exploring traffic sampling techniques and their effect on the characterization of wide-area high speed traffic. The project objective is to investigate the effect of sampling on our ability to answer selected questions about traffic characteristics on high speed networks. We are motivated by the increasing difficulty in fully monitoring high-speed wide area network environments. We therefore intend to investigate a variety of sampling parameters and frequencies, and compare the answers to various questions: packet type distribution, geographical distribution of traffic. We would like to assess confidence intervals for the resulting values. Eventually, we hope the project enables us to construct an optimal, stochastic sampling technique which responds to dynamic characteristics of the environment. Travel ====== Bilal Chinoy and Paul Love attended the Boston IETF. Paul Love attended the FARnet/NSF workshop on the NSF's draft solicitation for a new backbone. Paul Love UCL ---- Ian Wakeman gave a paper on Video Coding and Congestion Control at a Multi-service networks workshop in Abingdon, England. Tony Ballardie and Peter Kirstein attended IETF, as did a cast of several in the UK late into the evening, over vat audio and dvc video. Several (several media) conferences were held earlier in Western European Time between the UK and other nations/continents. John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. Thanks to Louie Mamakos a version of the Network Time Protocol Version 3 (NTPv3) supporting the RSA Message Digest 5 algorithm is now available and in test. Use of this algorithm allegedly avoids the red-tape export controls placed on the Digital Encryption Standard (DES) algorithm formerly used for this purpose. Cooper [Page 31] Internet Monthly Report July 1992 2. Thanks to the kindness of Digital Equipment, we now have a pair of DECstation 5000/240 workstations for use in timekeeping experiments. These are to be equipped with FDDI interfaces and flashy clock-interface boards capable of submicrosecond resolution. 3. The document "Simple Network Time Protocol (SNTP)" has been submitted for publication as an RFC. Preliminary copies in ASCII format can be found in louie.udel.edu:pub/ntp/doc/sntp.txt. 4. NTPv3 has been deployed in DARTnet and several overseas networks, besides many sites in the U.S. and Canada. It is hoped that widespread replacement of earlier versions can reduce the overheads at presently overloaded servers such as umd1.umd.edu, which now suffers some 70 packets per second, many times what was once thought a redline condition. Dave Mills (Mills@UDEL.EDU) WISCNET ------- The Wisconsin Department of Natural Resources joined the net in July. Their connection has been installed but the connection to their local LAN is not functioning pending acquisition of a network number and reconfiguration of existing IP nodes. Router software upgrades are in progress. As these are completed, we've turned on Cisco's priority queuing feature to improve response time for interactive traffic. Michael Dorl (dorl@macc.wisc.edu) Cooper [Page 32] Internet Monthly Report July 1992 DIRECTORY SERVICES ------------------ This section of the Internet Monthly is devoted to efforts working to develop directory services that are for, or effect, the Internet. We would like to encourage any organization with news about directory service activities to use this forum for publishing brief monthly news items. The current reporters list includes: o IETF OSIDS Working Group [no] o IETF DISI Working Group [no] o Field Operational X.500 Project - ISI [included] - Merit [no] - PSI [no] - SRI [no] o National Institute of Standards and Technology [included] o North American Directory Forum [no] o OSI Implementor's Workshop [no] o PARADISE Project [included] o PSI DARPA/NNT X.500 Project [no] o PSI WHITE PAGES PILOT [no] o Registration Authority Committee (ANSI USA RAC) [no] o U.S. Department of State, Study Group D, [no] MHS Management Domain subcommittee (SG-D MHS-MD) Tom Tignor (tpt2@isi.edu) DS Report Coordinator FOX -- FIELD OPERATIONAL X.500 PROJECT -------------------------------------- The FOX project is a DARPA and NSF sponsored effort to provide a basis for operational X.500 deployment in the NREN/Internet. This work is being carried out at Merit, NSYERNet/PSI, SRI and ISI. ISI is the main contractor and responsible for project oversight. ISI --- ISI is working on an RFC to be called "User's Guide to Portable DUAs." This document explains how users with an absolute minimal familiarity with X.500 and ISODE can easily set up DUAs in their own environments. The DUAs require only small portions of the ISODE environment to be present, sparing the user the hassle of dealing with ISODE's voluminous directory tree. This document Cooper [Page 33] Internet Monthly Report July 1992 gives simple setup procedures for four DUAs: "WHOIS", "de", "doog" and "ud". The document anticipates setup procedures for other DUAs as future additions. Tom Tignor (tpt2@isi.edu) NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY ---------------------------------------------- NIST/GSA X.500 Pilot -------------------- Dialup access to a Directory user interface is now available, for those agencies not in possession of Directory User Agent (DUA) software. Users may log in to an account on the pilot DSA host system via modem. The guest account will automatically run a Widget user interface and connect into the pilot DSA. Custos (the NIST X.500 Implementation) -------------------------------------- July saw the completion of a statistics package which enables us to glean usage information for the pilot, based on the operational log record produced by the DSA. Information collected includes: the number of DSA restarts (an indication of how many times the DSA was shut down or crashed each month); the number of incoming connections handled, both over the DAP, DSP and in total, which gives an indication of frequency of use; the number of Directory operations processed, an indicator of intensity of use; and a breakdown by operation of the kinds of operations performed, which gives an indication of the most common types of usage (such information will be useful in determining how to optimize a particular DSA configuration). Statistics will be collated on a monthly basis from now on and included with this report. The statistics for July 8 through July 31 were as follows: Number of DSA restarts: 6 Number of DAP connections: 13 Number of DSP connections: 0 Total number of operations: 41 DAP Operations: 41 DSP Operations: 0 Cooper [Page 34] Internet Monthly Report July 1992 Breakdown of operations: DAP: Read: 9 Compare: 0 List: 14 Search: 18 Add: 0 Remove: 0 DSP: Read: 0 Compare: 0 List: 0 Search: 0 Add: 0 Remove: 0 Looking to the Future --------------------- As the pilot gains momentum, it may be necessary to provide access from non-Unix based systems. One possible method of achieving this might be to use a "lightweight" DUA package, linked into a server based here at NIST. Several of these packages are available, eg for the Macintosh and the PC. They use a stripped down form of the Directory Access Protocol to communicate with a server running on a larger system. This server then formulates full DAP operation requests and ships them out to a DSA over the full protocol stack. John Tebbutt (tebbutt@rhino.ncsl.nist.gov) PARADISE -------- The last few months has seen the addition of several new countries to the international pilot: Brazil (Federal University of Rio Grande do Sul, Porto Alegre), Czechoslovakia (Institute of Automation & Communication, Banska Bystrica (Slovakia)) and Greece (Institute of Computing, Heraklio (Crete)). In addition the new states of Slovenia and Croatia are ready to register as c=SI and c=HR but will temporarily be listed as localities under the root. This is because the old ISO codes are compiled into ISODE 7.0, and so the new codes would not be accepted by DSAs running the old software. As of today, eight universities in Poland have joined the pilot. All these countries are running QUIPU DSAs. Keen interest is being shown in Hungary, Korea and Turkey who are all expected to run servers in the near future. Cooper [Page 35] Internet Monthly Report July 1992 The latest version of the PARADISE International Report (#3) is now available in hard copy as well as from the info-server. In addition to the country status notices, the report contains articles on the following: o Corporate Concerns o Service Providers o DSA Survey The project has also produced a number of metrics reports over the last few months which are (or will shortly) be available from the info- server (info-server@paradise.ulcc.ac.uk). These are: o DSA metrics o DUA metrics o Pilot metrics All three of these documents will be on rfc track. In addition to the near-conformance testing being carried out by the PTT Research Labs in the Netherlands, the project has been directly involved in interworking discussions and testing with ICL (UK), Siemens Nixdorf (Germany), U.COM X.500 (France) and DirWiz (Italy). Details of this work are contained in the first interoperability report. Also related to this activity, the project has produced a DSA survey of over 20 implementations. This is available as part of the International Report or electronically. "de" the PARADISE Directory Enquiries is available interactively from the central server (128.86.8.56, type dua at the login: prompt), or as part of ISODE 8.0. The project issued a third release of the software last month, which incorporates ufn searching, read/list opertations when accessing non-QUIPU DSAs (eg in France), and locality/ state searching. The project is also piloting a new tool, "idm" the interactive Directory manager, which will be run centrally (128.86.8.56, type idm at logi: prompt) and released to local sites on request. This tool allows users (with appropriate access control) to add new organsiations into the Directory and then to add, modify or delete entries. It is seen as an ideal way to help SMEs (small to medium size enterprises) actively participate in the pilot, as well as a tool to allow users in large organisations to have limited access to their own entries.
