Goals of New TWAREN (1)Goals of New TWAREN (1)

A physical network serves multiple purposes and logical networks production, general use general research experiment, testbed, special research

Provisioning services on multiple layers L1 lightpaths L2 VLAN L3 IP

1111

High reliability & availability (99.9% -> 99.99%) fault tolerance automatic protection if possible automatic failure detection and locating

Good performance: minimum number of routers between GigaPoPs

Flexible: can be easily and quickly to set up a logical network per user’s request

People skills: Optical network OAM

ConclusionsConclusions In this new architecture, IP and Optical ne

twork are integrated into one. With MPLS+L2 switches in core layer, mul

ti-point VLAN service is achieved. MPLS LSPs are configured with fast-rerou

te option for link protection. For lightpaths among GigaPOP and core

node, the automatic protection are configured.

When a core node fails, manual re-route of lightpath can be done.

Reduce circuit cost by half.
