TWAREN is a hybrid network. Its 100 Gbps backbone serves as the production and research networks, and its multiple optical segments are used for specific research needs such as lambda testing.
TWAREN has five core nodes and 12 regional network centers (a.k.a. GigaPOPs.) Its five core nodes are connected with a 100 Gbps backbone which are provided by two fixed network carriers, Chunghwa Telecom and Asia Pacific Broadband Telecom. Its 12 GigaPOPs are connected to its backbone with dual uplinks and 100G bandwidth to bring Taiwan’s universities and research institutions onto it. Other networked institutions connect to TWAREN’s backbone at their nearby GigaPOPs.
TWAREN’s five core nodes are strategically placed from southern to northern Taiwan, thus, covering the entire island. Together, the 5 core nodes form TWAREN’s primary optical switching backbone. They are located respectively as below:
(including academic institutions, research centers, and local government network centers)
These institutions are responsible for making their own connections to their nearby GigaPOPs. GigaPOPs will reserve connection points for those institutions that aren't able to connect to them for now but anticipate doing so in the near future.
TWAREN has two 10 Gbps international trans-Pacific network connection lines. One is from Taipei to Chicago, and the other one is from Hsinchu to LA. Besides, another 1 Gbps circuit is used to connect LA, Chicago, and New York all together. TWAREN connects to global advanced networks mainly via American advanced R&D networks: Internet2, StarLight, and Pacific Wave.
TWAREN’s Network Operation Center plays an important role in its networking maintenance. The NOC is situated at Southern Business Unit, NCHC and provides a 24/7/365 non-stopping monitoring/maintenamce service for broadband connection, co-location, proxy, SourceForge and project-based services.
