2006 / 01 / 25 Lambda Networking in TWAREN New Architecture Design NCHC, Taiwan
TWAREN New Architecture • TWAREN is the only national academic and research 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 2006. • More demands of integrating optical lightpaths with IP services. • Packets are transmitted over Lightpaths between GigaPOP and core nodes • Multi-point communication among core nodes is enabled by MPLS/VPLS technology in order to save the bandwidth
Design Considerations • Use current equipment, to save cost • To provide services of virtual networks (multiple point to multiple point) and dedicated lightpaths • Better performance • No single point-of-failure, highly fault tolerant • Scalable

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