CURRENT_MEETING_REPORT_ Reported by Gene Hastings/PSC Minutes of the Joint Network Joint Management Working Group (NJM) Below are the combined Minutes for NJM and Network Status Report. Announcements: Due to the number of presenters, there was an extension of Network Status Reports into part of the NJM session. Supplementary notes for the NETSTAT portion, as well as presentation slides can be found in Section 3 of the Proceedings. There was positive feedback after both sessions for having combined presentations and discussions spurred by them. Consequently the sessions will be more tightly coupled in the future. Mark Knopper, Jordan Becker - Merit/ANS T3 Network Status A number of refinements and enhancements are planned, including RS960 FDDI deployment, and routing software changes such that an ENSS will not announce 140.222 if it is isolated from the backbone. Changes in backbone internal configuration are planned to minimize coast-to- coast delay. Jordan said he will put the PostScript version of the delay map on line. (also included in Proceedings) Change tonight (17 November): CLNP will become encapsulated, [in one of the T1 PSPs] and transferred over IP, instead of being switched in a native stack. This is part of the migration plan to move all remaining traffic from the T1 net to the T3. It will initially remain on T1 net. General notes and announcements: o EASInet at CERN will have an ENSS, connected to NY. o Traffic Source/Destination pair statistics are sampled, with a frequency of 1 in 50. o Am map showing the T3 backbone with the T1 backup net is available online. Question: Do you have priority queuing for management traffic? - Not yet; AIX 3.2 will have priority queuing for routing traffic. o The MTU in the backbone is set to 1500 on most interfaces. With deployment of new interfaces, many are being changed to 4000. ENSS FDDI can do MTU discovery. The deployment strategy is designed to avoid fragmentation on Ethernet interfaces, at the potential cost of inefficient FDDI use in the short term. o The dismantling of the T1 backbone circuits begins 12/2 Within CNSS PoPs, there are DSU upgrades planned, granting multipoint capability, and redundancy within PoP. 1 o Merit/ANS have issued an invitation to users, vendors and developers to come to the ANS test net to test interoperability of new BGP support. Milo Medin - NASA Science Internet An upgraded, year-round link to McMurdo base in Antarctica will be through ARC2. It was a seasonal 56kb, and has been upgraded to full time 384kb via IntelSat IV Lessons learned from NSI operations: Don't encapsulate (DECNOT) on 56kb lines. NSI Currently does DECNOT on TCP. Doing it over UDP was a lose. DEC NSP is ``broken'' the way TCP used to be w.r.t. retransmission. With DECNOT, TCP does retransmission, and NSP does not have to. NSI network management is migrating to MSU (but not MCC) (``Polycenter 2000'') Future efforts: o Awaiting Commerce Dept. OK for ``Export of Internet'' to Russia to allow network links to same and other parts of FSU. o NASA participation with DoE ATM will have connections at Langley, Lewis, Goddard, Ames, JPL - AGS+. Bernhard Stockman, EBONE There is now a security access scheme in EBONE routers (Amalgam of Kerberos and TACACS). There will probably be a 256kb link from Bonn to Stockholm. Network Joint Management - 19 November 1992 Bob Collet - Sprint Sprint operates three internets, with Internet connectivity. 1. SprintLink (Domestic US) 2. ICMnet-2 (Atlantic) 3. ICMnet-3 (Pacific) Sprint uses cisco except in some private nets it uses Wellfleet. There are nine domestic customers, and nine more being provisioned. Will be demonstrating T3 P-P at COMNET '93 in February 1993. Most of the routers are owned by Sprint. There is some customer owned equipment, but only at customer premises. Sprint has management responsibility and sole configuration control of customer router. 2 Rich Fisher - GSFC Project group at Goddard Space Flight Center does data acquisition from satellites, and redistributes it to numerous terrestrial labs. RAC :== Remote Analysis Computer (All VAX) All links provided by PSCN (NASA ``phone co.'') Tony Hain - ESnet [There are no accompanying slides for this presentation.] The Department of Engergy's (DoE) original high speed RFP was two years ago, and began review in February 1992. An award was made to Sprint, with TRW and cisco as subcontractor. A protest was filed so the procurement is on hold. The General Accounting Office's (GAO) 90 day timer expires December 23rd. The GAO will say nothing before then...Therefore there will be a three month delay in deployment. Initially access will be provided at T3, eventually a mix, up to OC-12. All local loops will be fiber. It is NOT a managed router service. The DoE and NASA will accept raw ATM. The router will be a cisco AGS+ with a CSC-4 processor and HSSI interface for T3. The router will connect via Digital Link CSUs. A new router will be needed to go beyond T3 rates. The net will do IP and CLNP. Planners are trying to figure out DECNET Phase IV, and negotiating with DEC to make Phase V genuinely be CLNP (as opposed to being only close). They are still discussing which IGP to use. (contemplating OSPF and IBGP). Six DoE sites are planned as part of the initial project: 1. Lawrence Livermore National Laboratory 2. Lawrence Berkeley Laboratory 3. Los Alamos National Laboratory 4. FermiLab 5. Oak Ridge 6. Superconducting Supercollider, Waxahatchie, TX. Continued plans call for the eventual connection of all ESnet sites, but sites that are not currently connected to ESnet will not necessarily be connected directly. If they were already being considered for a T1, they may get a connection. In addition, there are 5 NASA planned as well: 1. Langley Air Force Base 2. NASA Lewis Research Center 3. Goddard Space Flight Center 4. Ames Research Center 5. Jet Propulsion Lab Mark Knopper asks: What is the plan and timeline for testing vs. 3 production? o Service will be brought up off-line o Several sites will be cut into ESnet o Procurement includes an off-line testbed Since NASA and DoE will be sharing a fabric, they will eventually move their peering to this net (vs. at FIXes) There will be several logical subnets on the fabric: o DoE internal o NASA internal o DoE-NASA ``Phantom DMZ'' for peering. SDSC has gotten funding from NSF to participate. Will initially be part of the DoE subnet. Tony will have more technical information in January (encapsulation, etc.). Mark Knopper: ERNET.(India Research And Education Net). ERNET folks visited several US operators and Internet researchers, including Merit. Funded by Indian Government and the United Nations. Phase III (refer to slides) uses VSAT for domestic networking due to inadequacy of domestic telecomm IP and CLNP over X.25. 128kb up, and 512kb down Original connection was Alternet UUCP, dialup uucp, analog leased uucp, analog leased SLIP (and improved UUCP performance, as TCP is better at line utilization) usually had > 20MB of mail in their queue. Use mostly Cisco MGS, some CGS. Currently has 1 class B network, nationwide... NJM Discussion o Route aggregation, BGP4 deployment can you do it? o Does there exist a CIDR traceroute? does anyone know how to interpret one? o Dennis Ferguson says that as a transition plan, it is easier for the midlevel to do route aggregation than the backbone. He suggests that such clients advertise both explicit routes and an aggregated route. The Backbone will install the explicit routes, and announce only the aggregated one. o Continued from BGP Deployment Working Group. (See also BGPDEPL Minutes): Ref. Claudio Topolcic's timeline. Must examine transition to CIDR - Tools? If operators do not do BGP4 by (date), 4 they will need to accept default only from backbone. What is that date? If Merit's deployment plan works, it may be December 31, 1993. o ROAD transition issues. Who really needs to do BGP4? Many ``stub'' or tail nets will not need to soon. What is the operational impact of dinosaurs? Will they really die out? Can we afford to sustain them?
