Outline
I’d like to focus on the networking for the intraregional connectivity within Asia(-Pacific) region
available for the HENP collaboration, but before
going into it I’ll talk on the inter-regional
connectivity first.

Inter-regional connectivity
– general A&R
– HENP dedicated

Intra-regional connectivity
– HENP dedicated
– APAN

Summary
Inter-regional connectivity
between Asia(-Pacific) region
and the other regions
Three ways to get the connectivity to
outside the region
 Hub
model
– A region has a hub through which each national
A&R network gets the outside connectivity.
The hub has big line(s) to the other regions.
 Parallel
model
– Each national A&R network in a region has its
own line(s) to the other regions.
 Hybrid
model
– Some national A&R networks have their own
lines, while the others depend on a hub.
 Asia
is in Hybrid model.
 Similar to Europe, where many countries
have their own lines to US, many countries
in Asia(-Pacific) have also their own lines to
US.

dedicated to HENP

•~10Mbps for KEK’s peering with ESnet at STARTAP
•~10Mbps for KEK’s peering with ESnet at San Jose
-waiting for an LBNL-SanJose circuit (a T3 circuit)
•~5Mbps for KEK’s peering with CERN
-CERN-London is configured in TEN-155’s MBS
•(~5Mbps for KEK’s peering with DESY)
These are guaranteed bandwidths configured in the
general A&R networks.

NACSIS’s upgrade
 NACSIS’s
lines are upgraded once per year.
– Domestic lines: every April
 The
biggest backbone will be 405Mbps in April 2000.
– International lines: every October
 NACSIS’s
future prospect
– Aggregated bandwidth to US/EU will be doubled
every year:
50Mbps(1997), 150Mbps(1998), 300Mbps(1999), 600Mbps(2000),
1.2Gbps(2001), 2.5Gbps(2002), 5Gbps(2003), 10Gbps(2004),
20Gbps(2005), …
Intra-regional connectivity
in Asia(-Pacific) region
(international connectivity within the region)
 As
the inter-regional bandwidths for
HENP are becoming rather big, the
intra-regional connectivity for HENP
is becoming more and more important,
especially in Asia.
Intra-regional lines dedicated to HENP
 KEK-IHEP (Beijing,
China)
 KEK-BINP (Novosibirsk, Russia)
 KEK-AcademiaSinica (Taipei, Taiwan)
KEK-IHEP link history
till July 1994, KEK-IHEP traffic was routed via
SLAC-IHEP satellite circuit.
 in July 1994, KEK-IHEP 64Kbps line was created.

– began as a satellite circuit temporarily and replaced by
a fiber circuit in April 1995
– SLAC-IHEP link was taken over by this line
upgraded to 128Kbps in October 1998.
 another upgrade is being studied.
 routing

– default route for all the outside connection from IHEP
KEK-BINP link history
till March 1998, KEK-BINP traffic was routed via
DESY-BINP satellite circuit
 in March 1998, KEK-BINP 128Kbps line, a fiber
circuit (partly microwave), was created.
 in September 1999, Moscow area (ITEP, MSU,
…) was connected with KEK via BINP.
 upgrade of the line is being studied.
 routing

– BINP-ESnet, MSU/ITEP-KEK/HEPnet-J
KEK-AcademiaSinica link history
till January 1999, KEK-Taiwan traffic was routed
via US.
 in January 1999, KEK-AcademiaSinica 128Kbps
line was created.
 upgrade of the line to a FrameRelay circuit
(1.5Mbps port, 512Kbps CIR) is being prepared.

 Asia
Pacific Advanced Network
Consortium

 started
in June 1997
 KEK will be directly connected with
IMnet/APAN on 1 March 2000.

 APAN
looks very useful for getting the
intra-regional connectivity for HENP.
 APAN is not automatically open to all the
A&R community. It is per project base.
Each project wishing to use the APAN
needs to be approved by its committee in
advance.
 A project application was submitted with
the project name “ACFA network” in
January 2000.
 It is being approved by the APAN
committee.
IP multicast with satellite
 Satellite
and data broadcasting might
be interesting especially in Asia.
 Using IP multicasting with usual TV
antennas and TV tuners for receiving
data can be very interesting. It can
be cheap and can be used everywhere
in Asia.
 Data transfer rate is ~30Mbps with
usual TV antennas, and can be
~1Gbps with expensive earth stations.

Summary
 Compared
with the inter-regional
connectivity for HENP which is becoming
bigger and bigger, the intra-regional
connectivity in Asia(-Pacific) still remains
poor.
 We are trying to improve it
– by utilizing APAN and
– by upgrading the HENP dedicated lines.
