The Evolution of TANet2
 TANet2 is a national research network, in


operation since 1998 to serve academia and
research institutions. TANet2 is an MOU
partner of Internet2 and part of APAN-TW.
Since 2004, a new, 20G backbone network,
TWAREN (TaiWan Advanced Research and
Education Network) has been in operation. It
serves the same clientele.
The international circuits are redesigned, with
state-of-the-art optical technologies served by
TAIWANLight.

Lightpath Definition
 A lightpath is a point-to-point channel which
the NIC takes as a dedicated line with a given
service level guarantee.
SONET/SDH TDM channel
 WDM wavelength
 MPLS layer-2 VPN
 any concatenation of the above

 Only one hop between the endpoints of a
lightpath!

January 2005 Upgrade
 In partnership with Chunghwa Telecom. (Its

overseas division, TWGate). New circuit due for
completion by mid February.
New circuit comes with installation of ONS devices
at five sites:
STTL, Palo Alto, LA, Chicago, NYC
 In Chicago, there is one more colo-site at Equinix
besides STARLight.

 Combined bandwidths for the Trans-Pacific links
(un-protected) is 4.5 Gb/s, each at 2.5 Gb/s shy.

Virtual Topology Design
 TAIWANLight now connects to the TWAREN
optical network instead of the production
Layer 3 router.
The Equinix in Chicago is considered as a
bypass site
 A total of 23 ONSs are included for this new
layout of lightpaths
 Provides backup routes and separate peerings

Features of New TAIWANLight
 There are direct lightpaths from Taipei,
Hsinchu, and Tainan to the five colo-sites for
peering, each one has at least one protected
path
Only one hop from Taiwan to US!
 More reliable and load-balanced

 Besides commodity peering lightpaths, lots of
bandwidth are left for future possible
collaboration
Inter-domain lighpath exchange
 HD video streaming
 Other E-Science applications
