Bill Manning, Sesquinet
Sesquinet has a staff of 3, and recently installed and moved to an
FDDI DMZ for their ANS connection. Usage is growing by 15% per month
Michael Patton, DSI (Defense Simulation Internet)
(See slides & map)
The Defense Simulation Internet is used to connect the defense
industry. and perform mission-specific experiments (like encrypted
video). It has a T1 cross-country backbone (see map for more
detail.)
Recent Exercises (listed on slide).
Jeff Burgan, NASA Science Internet (see also slides)
It's the 10th Anniversary of the DNS RFC!
Overview
A T3 has been installed from Goddard (GSFC) to SURAnet, and another
T3 from Goddard to NRL (Naval Research Labs) (using Cisco)
Routed traffic is both IP and Phase IV DECnet, with some CLNP.
NSI provides mail & protocol interoperability services
Maps are available via anonymous ftp from nsipo:nsi/maps/*
Recent (since Columbus IETF) stuff
The UK fat pipe has been transitioned to ICM/Sprint, NASA now has a
256kb dedicated link to ULCC (London)
Australia (AARnet) link has been upgraded to T1.
Japanese links have been reterminated to FIX-West (from Hawaii)
WIDE - 192kb
TISN - upgraded 128kb to 512kb
Korea was upgraded to 256kb
Hong Kong link has been upgraded to 128kb
FIX-West transitioned to FDDI (but ESnet still Ethernet) Mbone
router and DNS servers live on the Ethernet
NASA/NSF support for Antarctic connectivity: Upgrade to t1 (IP 512k,
balance is video) to McMurdo Station
Future
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 re-
combine loser spped channels to HSSI - (Digital Link is smart
about failed links, even about error/second threshold, deduces
composite clocks.)
General purpose Internet connectivity to Russia via IKI (Russian
Space Research Institute) at 256kb is scheduled for ca. Jan '94.
There will be ~10 additional sites added, using analog p-p links.
The connectivity is basically confined to 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.
NSI expects to install a link to Argentina Space Institute at 64Kb
BGP deployment!!!
(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.
ATM
The DoE/NASA procurement has been re-cycled. Proposals are being
evaluated.
NASA has gotten their own permission to procure ATM service.
Hopes to have ATM, at latest middle '94.
Jordan Becker, ANS (see slides)
Busiest ANS link is Chicago to Cleveland (in PPS)
Spike in external route flap last week
Andrew Parton: an ignorant or unfriendly site sent UDP packetsto
every sequential host in the address space. Since this forces a
new router cache entry with each successive packet, it can make a
router (empiracally dtertermined 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 source started with low class A nets, the flaps moved from
provider to provider. Hit Alternet at net 7.

Mike O'Dell, Alternet
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 7 major hubs, plus Jan Jose. Alternet's 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 net on fabric with multiple
customers. (Alternet is the largest customer willing to be
publicised - 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.
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 online: ftp.uu.net:uunet-info
Alternet staff report satisfaction with the caliber of MFS Telco
people and DataNet data communications people.
Scott Bradner, COREN
Carrier negotiations are still underway, but are 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 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 2 vendors of CSU/DSU have signed on, so far. COREN has
set up a testbed, with BGP4,
COREN has 8 regionals as its founders, plus a number of undisclosed
committed or potential subscribers.
COREN is working in parallel to RIPE routing database effort, and is
starting to work with Merit on transition issues.
Bernhard Stockman, Ebone
In the last year, there has been rapid expantion 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 to a single point, the GIX in washington DC. (Andrew
Parton observes that the GIX Ethernet is close to saturation)
The EBONE is now running BGP4 on all EBS (Ebone Border Systems, 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:
EUNET
HEPNET
SPAN
Unisource Business Systems (UBS)
Joint venture of Netherlands and Swedish PTTs + Swiss PTT
Stimulated by call for tender for Pan-European x.25
EMPB - European MultiProtocol Backbone
DANTE, Inc.
Formed by European R&E community.
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 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. (MAC layer extensions....)
