  2. The Revolution of TANet2 • TANet2 is a national research network, in operation since 1998 to serve researchers in academia and research centers with direct circuits to Internet2 community. • Since 2004, the domestic backbone has been reformed with 20G capacity known as TWAREN(TaiWan Advanced Research and Education Network) . • The international circuits are reorganized with state-of-the-art optical technologies served by TAIWANLight.

Dual vendor-provisioning at 10 Gbps each. Optical Network Acquired dark fiber segments in experimental use

  5. 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!

  7. Lightpath Customers • Video streaming testbed among NCTU, NTU, NCKU and NSYSU. • Medical images and data transmission between NTU Hospital and its Yunlin division. • Volumes of data synchronization between the headquarter of National Health Research Institutes in Zhunan and its office in Taipei.

  8. Collaboration with Canarie • NCHC's Lab assists with Canarie for developing SDH version of UCLP (user-controlled lighpath) software.

  12. January 2005 Upgrade • In partnership with Chunghwa Telecom. (Its overseas division, TWGate), won the recent open tender. Circuit due for completion by 1.31. • New circuit with installation of ONS devices at five-points: • STTL, Palo Alto, LA, Chicago, NYC • In Chicago, there is one more colo-site at Equinix besides STARLight. • Combined bandwidths for the X-Pacific links (un-protected) is 4.5 Gb/s, ea. at 2.5 Gb/s shy.

  14. Virtual Topology Design • TAIWANLight now connects to the TWAREN optical network instead of the production Layer 3 router. • Total 24 ONSs are included when planning the layout of lightpaths • Future challenges of inter-domain lighpath exchange
