20090073988 | SYSTEMS AND METHODS FOR A SELF-HEALING CARRIER ETHERNET TOPOLOGY - Systems and methods for self-healing Ethernet topologies which are compatible with PBT, which use standards-based protocols, which do not self-configure, and which use Ethernet OAM are provided. Interconnected nodes are configured with a primary and secondary path which is determined by VLANs, MPLS label, Provider Backbone Bridge Traffic Engineering (PBB-TE) VLAN ID (VID), Frame Relay (FR), Asynchronous Transfer Mode (ATM) Virtual Circuits (VCs), and the like. One or more head-end nodes are designated for terminating each path and for performing cross-connects between the primary and secondary paths. IEEE 802.1ag Continuity Check Messages (CCM) are transmitted by all nodes on both the primary and secondary routes.
