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
![Page 5: CHEP2000 conference at Padova on 9 February 2000 Yukio.Karita@kek.jp Networking in Asia](https://reader038.vdocument.in/reader038/viewer/2022110103/5681493b550346895db68430/html5/thumbnails/5.jpg)
Inter-regional connectivity between Asia(-Pacific) region
and the other regions
![Page 6: CHEP2000 conference at Padova on 9 February 2000 Yukio.Karita@kek.jp Networking in Asia](https://reader038.vdocument.in/reader038/viewer/2022110103/5681493b550346895db68430/html5/thumbnails/6.jpg)
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.
![Page 7: CHEP2000 conference at Padova on 9 February 2000 Yukio.Karita@kek.jp Networking in Asia](https://reader038.vdocument.in/reader038/viewer/2022110103/5681493b550346895db68430/html5/thumbnails/7.jpg)
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.

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)
![Page 14: CHEP2000 conference at Padova on 9 February 2000 Yukio.Karita@kek.jp Networking in Asia](https://reader038.vdocument.in/reader038/viewer/2022110103/5681493b550346895db68430/html5/thumbnails/14.jpg)
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.

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

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.
![Page 25: CHEP2000 conference at Padova on 9 February 2000 Yukio.Karita@kek.jp Networking in Asia](https://reader038.vdocument.in/reader038/viewer/2022110103/5681493b550346895db68430/html5/thumbnails/25.jpg)
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.
