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.

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.

SuperSINET SuperSINET is a networking project associated w
ith 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))

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 telec
ommunication circuits.

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

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 M
bps (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.

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.
