TWAREN New Architecture TWAREN is the only national academic and resea
rch backbone in Taiwan that provides layer one optical lightpaths and layer three routing and peerings. The lease of circuit is going to be due in August 200
6.
More demands of integrating optical lightpaths with IP services. Packets are transmitted over Lightpaths between Gi
gaPOP and core nodes Multi-point communication among core nodes is ena
bled by MPLS/VPLS technology in order to save the bandwidth

Design Considerations Use current equipment, to save cost To provide services of virtual networks (multipl
e point to multiple point) and dedicated lightpaths
Better performance No single point-of-failure, highly fault tolerant Scalable

TANET/TWAREN IP Service TANET is the academic network connecting
colleges, high schools and elementary schools in Taiwan.
TWAREN production network provides research backbone connecting among universities, research centers and international I2 partners
The new architecture will provide two virtual networks to meet the basic service.

Conclusions In this new architecture, IP and Optical networ
k are integrated into one. With MPLS+L2 switches in core nodes, multi-
point VLAN service is achieved. MPLS LSPs are configured with fast-reroute o
ption for link protection. For lightpaths among GigaPOP and core node,
the automatic protection are configured. When core node fails, manual re-route of light
path can be done.
