Three Networks Servicing R&E Communities in Taiwan
Three networks in Taiwan provide network services for the R&E communities
TANet, funded by the Minitry of Education, leases bandwidth from commodity vendors. It services higher education and K-12.
TANet2, funded by the National Science Council, is operated by the NCHC
ASNet, gets funding largely from the NSC, is managed by the Academia Sinica
The circuit acquisition is thus sometimes a tripartite effort, done jointly

TANet2 and TWAREN TANet2 is a national research network. It has be
en in operation since 1998 to service R&D TWAREN is the next version of TANet2, re-desig
ned with three levels of services –production, research and optical networks. TWAREN (TaiWan Advanced Research & Eduction Network)
The production network of TWAREN has just begun operation. Its research network and optical network are being implemented.
The two networks share the same circuits for international connectivity. Both managed by the NCHC.

Meshes in with APAN Infrastructure
Taiwan is a well-connected APAN member Meshes well in the APAN infrastructure fabr
ic For other R&E networks in Asia Pacific regi
on, Taiwan is very well-suited as an access point for peering and transit; and its multiple links as backup routes for other links.
Asian-Pacific PoPs Links to HK and Sg make TW, HK and SG e
quivalent PoPs which may serve as access points for other APAN networks
