## Outline

- Changes within Japan
- SuperSINET
- Changes in international connectivity
- NII’s US/Europe link upgrade
- Links within Asia
- HEP links
- APAN
- Security AdHoc meeting

## Changes within Japan

- SuperSINET will start its service in January 2002
- Intended to be fully photonic
- 10 λ’s from KEK
- One for 10Gbps IP backbone
- Seven for direct GbE (or 10GbE) to university HEP
- HEP VPN (or APN) within SuperSINET
- MPLS-VPN for HEPnet-J
- GbE’s to extend Workgroup VLAN’s in KEK to university HEP

## Slide 4

## MPLS-VPN for HEP

- Tokyo Hub

- Osaka Hub

- Nagoya Hub

- Osaka U

- Kyoto U

- Nagoya U

- KEK

- Tohoku U

- U Tokyo

- MPLS

- SuperSINET
- MPLS router

- OC48c’s

- GbE

## Changes in international connectivity

## NII’s US/Europe link

- SuperSINET’s plan (Jan. 2003)
- Two λ’s to US Westcoast  (λ2.5Gbps?)
- One is for IP backbone
- One is for direct GbE’s
- to be used for KEK-CERN Grid Testbed
- Canarie can bridge SuperSINET’s λ and DataTAG’s λ?
- Minor upgrade in Jan. 2002
- Five OC3 POS’s for the default IP traffic
- Three 75Mbps ATM-PVC’s for mission-oriented traffic
- One is to connect with Abilene
- One is to connect with Esnet
- One is to connect with Geant
- 75Mbps is to fullfill NII’s contribution for the NII-Dante OC3 connection proposed by Dante last year

## NII’s US/Europe link as from Jan. 2002

## Bandwidth for HEPin NII’s US/Europe link

- Bandwidth as from Jan. 2002
- KEK-Esnet 20Mbps ( current 10Mbps)
- KEK-CERN 20Mbps ( current 4Mbps)
- KEK-DESY 10Mbps ( current 2Mbps)
- How shall we do in Geant?
- MBS (Managed Bandwidth Service supported in TEN-155) is not supported in Geant for the present.
- So the both PVC (to CERN and to DESY) are currently terminated at Geant router at London.
- Can we expect MPLS-VPN support or something else in Geant?

## Links within Asia

- HEP links
- KEK-AcademiaSinica (TW) 1.5Mbps FrameRelay
- To be merged into AcademiaSinica-APAN 45Mbps (coming).
- HEP traffic will have priority there.
- KEK-BINP (RU) 128Kbps  512Kbps
- Its Japanese half circuit has been ready for the upgrade since early 2001.
- Waiting for US’s support for its Russian half circuit.
- KEK-IHEP (CN) 128Kbps
- Once said to be merged into CAS (Chinese Academy of Science)’s international link, but may continue to exist even after IHEP is connected to CAS.
- IHEP-CAS 2Mbps link is being delayed.
- APAN
- Expected to provide the intra-regional connectivity for HEP within Asia, especially to Korea.
- “ACFA network”

## APAN

-  Intra-regional APAN lines

- APII   Asia Pacific Information Infrastructure
-               a project initiated by APEC

## “ACFA network” project

- Abstract of project
-      ACFA stands for Asian Committee for Future Accelerators.  Under ACFA, many institutes in the Asia Pacific region are collaborating in research with accelerators.   A quality computer network is crucial for this collaboration, and is expected to be provided by APAN.
- Expected result
-      The infrastructure for the well collaboration in ACFA is established.
- Special feature of traffic
- Collaborative tools including the video conferencing
- Access to large databases

- APAN is not automatically open to all the A&R community.
- Its use is granted per project base.

- Countries in Asia(-Pacific) requiring connectivity for the ACFA 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, CN, PH, TH, SG, AU (now)
- 				  to TW, VN, MY, ID (coming)

## Security AdHoc meeting

- Held at KEK on 5-6 December 2001 with participants from SLAC, FNAL, BNL, CERN, DESY, and KEK.
- Had valuable information exchange and discussions on VPN, mobile PC support, video conferencing, high speed data transfer bypassing the firewall, .... from the security’s point of view.
- Next meeting will be held at US EastCoast in autumn 2002.
