1. SINET updates Jun Matsukata National Institute of Informatics (NII) Research Organization of Information and Systems jm@nii.ac.jp January 24, 2005

2. 2 Networking at NII NII operates SINET and Super SINET which serves as the information network infrastructure for the national research and higher educational community in Japan. So, SINET and Super SINET plays the role of an NREN in Japan. Just being reorganized under a new concept focusing on broader targets covering applications as well…

3. 3 SINET SINET serves as the information communication infrastructure for the research community in Japan covering the higher educational community as well. Universities and academic research institutions are connected.

4. 4 Super SINET A networking project associated with SINET which was aimed at promotion of advanced scientific researches Implemented through a three+ year joint research project with the awarded telecommunication company (January 2002 to March 2005), and will continue to exist Integrated with SINET as a single operation entity

5. 5 Recent changes Circuit renewal of SINET and Super SINET International connectivity Back of transpacific portion of APAN Upgrade of the circuits to Thailand Upgrade of connectivity to U.S.A.

6. 6 Circuit renewal of SINET and Super SINET. By April 2005 Most circuits will be replaced. No remarkable change in topology Backup to major network nodes provided by Gigabit Ethernet clouds. More cooperation with APAN

7. 7 Planned configuration from April 2005 SINET and Super SINET (planned configuration as of April 2004)

8. 8 International connectivity December 2004 Started to provide backup for the transpacific portion of APAN January 2005 Upgrade of the 2 Mbps link to Bangkok, Thailand to 45 Mbps Connecting SINET (NII) and ThaiSARN (NECTEC) as before. April 2005 OC48 x 4 to NYC will become OC192 A new circuit (OC48) to LA

12. 12 More cooperation with APAN Cooperation with TransPAC2 project Now we provide backup for the transpacific portion of APAN. Upgrade of the circuit to Thailand which has been shared among APAN participants Other kinds of cooperation (including non- networking)

13. 13 Super SINET - a brief introduction

14. 14 Super SINET Implemented through a joint research project with the awarded telecommunication company Two modes of network services, shared backbone and point-to-point, have been provided for more than two years (since January 2002). OXCs were introduced for expedited provisioning and faster restoration of services.

15. 15 Network services provided by Super SINET Shared backbone Point-to-point Physical (light path, lambda, dedicated circuits, etc.) Virtual (LSP, etc.)

16. 16 Shared backbone 10 Gbps IP backbone Most Super SINET sites are connected with a 10 Gbps circuit. The backbone network is shared among the research and educational community. The network is IP based. Both IPv4 and IPv6 are supported. IPv6 is tunneling based for the moment though.

17. 17 Point-to-point Point-to-point services are provided to research (or users) groups. Each users group can make exclusive use of the connectivity provided. Variations of point-to-point services Physical Virtual or logical N.B. The term point-to-point might be not good, since it is often the case that services are extended to multi- point. Term site oriented might be more appropriate

18. 18 Point-to-point (contd) Point-to-point (physical) Gigabit Ethernet bridge Layer 3 protocol independent Based on physical resources reserved OC48 circuit This is actually provision of lambda. N.B. A lambda is an optical fiber if not multiplexed, or a wave length of a wave length multiplexed optical fiber.

20. 20 Point-to-point (contd) Point-to-point (virtual) MPLS VPN (Layer 3) Based on virtual resources Virtual or logical networks sharing the resource of the IP backbone. Multi-point services are also available.
