Abstract
The present invention provides a method and device for protective switching of pseudo-wires on a Packet Switching Network. The method includes grouping the pseudo-wires on the Packet Switching Network into a working pseudo-wire group and a protective pseudo-Wire group corresponding to each other's relationship of protection; performing on services the protective switching between the working pseudo-wire group and the protective pseudo-wire group according to the state of the working pseudo-wire group and protective pseudo-wire group. The method of the present invention can be used to perform edge-to-edge grouped protective switching of the pseudo-wires on the Packet Switching Network.
