Outline

I’d like to focus on the networking for the intra-regional 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.

General A&R lines to US JP-US NACSIS ~300Mbps

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.

routing– TAnet-AcademiaSinica-KEK-SINET-IMnet

APAN

Asia Pacific Advanced Network Consortium– http://www.apan.net

started in June 1997 KEK will be directly connected with IMnet/

APAN on 1 March 2000.

Countries in Asia(-Pacific) requiring connectivity for the HENP collaboration– JP, KR, CN, TW, PH, SG, IN, ID, VN, TH, RU, MY,

AU HENP lines

– KEK to CN, RU, TW APAN lines

– APAN_Tokyo to KR, PH, TH, SG, AU (now)

to VN, MY, ID (coming)

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.
