Multi-Domain VLAN Path Signaling Method Having Tag Swapping Function for GMPLS Controlled Wide Area Layer-2 Network

A multi-domain GMPLS layer-2 switch capable network with VLAN tag swapping is demonstrated for the first time. In this demonstration, we verify three new features; establishing path with designating VLAN IDs, swapping VLAN ID on prototype switch, and management of VLAN IDs per domain. Using those three features, carrier-class multi-domain Ethernet backbone networks which supports independently resource management per domain can be established. key words: GMPLS, RSVP-TE, Layer-2 Switch, VLAN
