CURRENT_MEETING_REPORT_ Reported by Eugene Hastings/Pittsburgh Supercomputing Center Minutes of the Joint Sessions of the NJM and NETSTAT Working Groups Presentation slides from the NSI and ANSnet status reports can be found in Section 3 of the proceedings. SESQUINET - Bill Manning Sesquinet has a staff of three, and recently installed and moved to an FDDI DMZ for their ANS connection. Usage is growing by 15% per month. Defense Simulation Internet - Mike Patton The Defense Simulation Internet (DSI) is used to connect the defense industry and perform mission-specific experiments (like encrypted video). It has a T1 cross-country backbone. NASA Science Internet - Jeff Burgan It is the 10th Anniversary of the DNS RFC! A T3 has been installed from Goddard Space Flight Center (GSFC) to SURAnet, and another T3 from GSFC to Naval Research Laboratory (NRL) (using cisco). Routed traffic is both IP and Phase IV DECnet, with some CLNP. NSI provides mail and protocol interoperability services. Maps are available via anonymous FTP from nsipo:nsi/maps/*. Recent accomplishments include: o The United Kingdom fat pipe has been transitioned to ICM/Sprint. o NASA now has a 256kb dedicated link to ULCC (London). o Australia (AARnet) link has been upgraded to T1. o Japanese links have been reterminated to FIX-West (from Hawaii). - WIDE - 192kb - TISN - upgraded 128kb to 512kb o Korea was upgraded to 256kb. o Hong Kong link has been upgraded to 128kb. o FIX-West transitioned to FDDI (but ESnet still Ethernet) Mbone router and DNS servers live on the Ethernet. o NASA/NSF support for Antarctic connectivity: Upgrade to T1 (IP 512k, balance is video) to McMurdo Station. Future plans include: 1 o NSI Backbone upgrades using inverse multiplexers. - NASA internal telecomm does multiplexed T3, but cannot offer channel breakout at greater than E1, so NSI is using inverse multiplexers to recombine lower speed channels to HSSI. - Digital Link is smart about failed links, even about error per second threshold, and deduces composite clocks. o General purpose Internet connectivity to Russia via IKI (Russian Space Research Institute) at 256kb is scheduled for circa January 1994. There will be about ten additional sites added, using analog point-to-point links. The connectivity is basically confined to the Moscow area. NASA went through COCOM to approve equipment and Internet service. NASA must retain physical and configuration control, but routes will be exported outside of NSI. o NSI expects to install a link to Argentina Space Institute at 64Kb BGP deployment! They are looking at multicast routing using MOSPF. Proteon supports MOSPF/DVMRP coupling. You can open a tunnel to a Proteon router and have it do multicast. o ATM: The DoE/NASA procurement has been re-cycled. Proposals are being evaluated. NASA has gotten their own permission to procure ATM service and hopes to have ATM, at the latest by mid 1994. ANS - Jordan Becker The busiest ANS link is Chicago to Cleveland (in PPS). There was a spike in the external route flap last week. Andrew Partan reported that an ignorant or unfriendly site sent UDP packets to every sequential host in the address space. Since this forces a new router cache entry with each successive packet, it can make a router (empirically determined to include cisco) overflow routing cache. The source, albeit unconfirmed, is believed to be an address in Taiwan. Alternet routers got full caches, memory leaks caused dropped BGP sessions. As the source started with low class A networks, the flaps moved from provider to provider, hitting Alternet at network 7. Alternet - Mike O'Dell Alternet is now running on an ATM Backbone, sourced by MFS DataNet. The physical topology is a large ring, with cut-through paths, interconnecting Newbridge ATM switches. All switches are interconnected with path diverse dual T3 links. The lines are for redundancy, with a box that does hot fallback between T3s (the ATM switch only sees one at a time). Alternet now has ATM in seven major hubs, plus San Jose. Alternet's 2 access to this ATM fabric is via a 10Mb AUI connector, behind a learning half-bridge. MFS DataNet takes care of the internals. (It will be some time before Alternet considers a native ATM connection---the cisco ATM Applique is said to cost $30k!) Since one can in principal do FDDI to NewBridge switch, it will be a while before other connections are needed. MFS DataNet provides a virtual private network on fabric with multiple customers. (Alternet is the largest customer willing to be publicized---there are other, private users of MFS DataNet in the banking and insurance industries.) DataNet owns the switches, but buys the circuits from the regular suspects: WilTel, etc. Concerning management, there is a list of criteria (bandwidth, delay, etc.) for MFS operations. Alternet's Demark is the AUI. MFS has just announced DataNet service to London. An overall map is available online: ftp.uu.net:uunet-info. Alternet staff reports satisfaction with the caliber of MFS Telco people and DataNet data communications people. COREN - Scott Bradner Carrier negotiations are still underway, anticipated to close within a couple of weeks. When a carrier is selected, substantial workouts will be performed. There is an (unspecified) fallback plan if a selected carrier is unsuitable. COREN's view of the carrier network is still under discussion. COREN's interface to the LD carrier is SMDS initially, and is planned to migrate to ATM. Its DMZ is parallel Ethernet and FDDI. COREN has also put out an RFI on NOC services, and put out an invitation to participate in equipment evaluation. cisco and Wellfleet and two vendors of CSU/DSU equipment have signed on so far. COREN has set up a testbed, with BGP4. COREN has eight regionals as its founders, plus a number of undisclosed committed or potential subscribers. COREN is working in parallel to the RIPE routing database effort, and is starting to work with Merit on transition issues. EBONE - Bernhard Stockman In the last year, there has been rapid expansion into eastern Europe. Countries near Austria are now connected to Vienna hub. Warsaw (currently connected to Vienna and Stockholm) may become another BB site, feeding Baltic. Within the last year, all of the transatlantic lines have been connected 3 to a single point, the Global Internet Exchange (GIX) in Washington, DC. (Andrew Partan observed that the GIX Ethernet is close to saturation.) The EBONE is now running BGP4 on all EBONE Border Systems (EBS), and will not do proxy aggregation for stability reasons. EBONE route policy filters are performed by means of comparing an administrative database with a live routing table. Connections to other providers include: o EUNET o EPNET o SPAN o Unisource Business Systems (UBS) This is a joint venture of Dutch, Swedish, and Swiss PTTs, stimulated by a call for tender for Pan-European X.25. o European MultiProtocol Backbone (EMPB) DANTE, Inc., formed by the European research and education community is reselling EMPB as Europanet, in a bundle with X.400 and X.500 services. There is a 1Mb connection between EBONE and EMPB in Amsterdam. Because of the overlap between communities, there are expected to be organizations leaving EBONE for EMPB. Trying to extend the logical boundary of the GIX to Stockholm and Paris to support interconnections.
