Abstract:
1. A method for scalable and rapid Ethernet fault detection, comprising: configuring a Maintenance Intermediate Point with Maintenance Entity End Point information, wherein a Maintenance Entity End Point sources and sinks Carrier Ethernet Connectivity Fault Management frames and the Maintenance Intermediate Point processes and forwards Carrier Ethernet Connectivity Fault Management frames, and wherein the Maintenance Entity End Point is configured with Carrier Ethernet Continuity Check Message polling disabled; monitoring at the Maintenance Intermediate Point for a link fault on a link connection to adjacent nodes; initiating a transmission from the Maintenance Intermediate Point of a Continuity Check Message with a Remote Defect Indication set in a reverse direction of the link fault to the Maintenance Entity End Point responsive to detecting the link fault, wherein the Maintenance Intermediate Point was previously operable to receive, process, and forward, but not generate, Continuity Check Messages; and initiating a transmission from the Maintenance Intermediate Point of a Continuity Check Message with the Remote Defect Indication reset responsive to clearing of the link fault.
