Abstract
A method for linear protection for a network element communicatively coupled to another network element included in a node portal located at the edge of an administrative network domain includes exchanging linear automatic protection switching ('APS') messages with clients in the administrative network domain over one or more path pairs. The path pairs include a working path communicatively coupling a client and the network element and a protect path communicatively coupling a client and the other network element. The method also includes translating the linear APS messages into a shared mesh protection message and exchanging the shared mesh protection message between the network element and the other network element over an intraportal link. The shared mesh protection messages include information concerning a plurality of working paths.
