  1. SINET Update and Collaboration with TEIN2 Jun Matsukata National Institute of Informatics (NII) Research Organization of Information and Systems jm@nii.ac.jp August 25, 2005

  2. SINET and SuperSINET • NII operates SINET and SuperSINET which serve as the information communications network infrastructure for the national research and higher education community in Japan. • SINET with SuperSINET together plays the role of an NREN in Japan.

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

  4. SuperSINET • SuperSINET is a networking project associated with SINET which was aimed at promotion of advanced scientific researches. • SuperSINET is integrated with SINET as a single operation entity. • Two modes of network services • Shared backbone (IP packet switched) • Dedicated • Physical (Gitabit Ethernet bridge circuits, etc.) • Virtual (MPLS VPN (L3))

  5. SuperSINET (continued) • First phase: from Janurary 2002 to March 2005 • SuperSINETwas implemented through a three+ year joint research project with the awarded telecommunication company. • Second phase: from April 2005 • SuperSINET uses commercially available telecommunication circuits.

  6. Topology of the Backbone Network of SINET/SuperSINET Tokyo Osaka Nagoya SuperSINET Nodes (PoPs) SINET Nodes (PoPs) As of April 2005

  7. Recent changes • Circuit renewal of the backbone of SINET and SuperSINET • Due to the transition from phase 1 to phase 2 • International connectivity • Backup of the transpacific portion of APAN • Upgrade of the circuit to Thailand • Upgrade of connectivity to U.S.A.

  8. Circuit renewal of SINET and SuperSINET. • Completed by April 2005 • Although most circuits were replaced, there was no remarkable change in topology. • Backup of the links to major network nodes using Gigabit Ethernet clouds.

  9. International connectivity • December 2004 • SINET started to provide backup for the transpacific portion of APAN (i.e. TransPac2). • January 2005 • The 2 Mbps link to Bangkok, Thailand was upgraded to 44 Mbps (ATM), connecting SINET (NII) and ThaiSARN (NECTEC) as before. • April 2005 • OC48 (2.4 Gbps) x 4 to NYC became OC192 (10 Gbps). • A new OC48 link to LA was installed.

  11. Upcoming and Future Issues • Design of next generation architecture of SINET • Two new intra-Asia links to be installed

  12. Two New Intra-Asia Links • Two OC12 (622 Mbps) intra-Asia links, between Tokyo and Hong Kong and between Tokyo and Singapore, will be installed by January 1, 2006. • Will form a part of the TEIN2 backbone. • Will be operated by NII in collaboration with TEIN2 as well as APAN.
