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.
