要旨: Wide-Area-Ethernet Service provides multiple inter-connections among customers’ LANs. In Wide-Area-Ethernet network, Virtual paths are established on layer-2 by VLAN (Virtual LAN) technology. Network switches read VLAN tag, path identification extended bit in Ethernet frame, and determine forwarding direction for each frame. We need to setup VLAN configuration of each switch to establish new path. GMPLS is able to setup the switches’ configuration automatically and establish the new path just after customer demand. We are researching on this protocol’s details, exchanged VLAN information, controlling switches, using limited numbers of VLAN IDs, and others. We presentation addresses Layer-2 Switching Capability (L2SC) with VLAN tag swapping. In Wide-Area-Ethernet network, same VLAN ID is used throughout a path. However, a number of VLAN ID is limited to 4096 due to extended frame format, thus there is a limit to the number of paths. VLAN swapping enables to use more VLAN IDs in a network like a Wavelength Converter.
We implemented a VLAN swapping function on Linux based PC and controlled the function by using GMPLS. In the experimental network, we used VLAN tag swapping switches that implemented by Linux PC. Multiple paths can be established by VLAN tag based switching that includes VLAN tag swapping.
