Abstract
The present disclosure provides systems and methods for Ethernet Connectivity Fault Management (CFM) extensions to provide a CFM messaging mechanism for support of information exchange and the like, in addition to end-to-end connectivity and fault management. In an exemplary embodiment, the present invention utilizes CFM extensions to provide Pseudowire (PW) MAC addressing. Here, the present invention can enable the exchanging of MAC addresses and other attributes for PDH pseudowire transport. Advantageously, this avoids involving the OSS/EMS/NMS in pre-provisioning these necessary but arbitrary attributes across the network elements supporting a pseudowire service. Also, the present invention can be extended to support numerous other applications involving sharing of attributes between nodes over the extensions provided herein.
