摘要：
The present invention provides scalable and rapid Ethernet fault detection which eliminates the requirement to contiguously send heartbeat frames at regular intervals to detect connectivity faults for each Ethernet Path. The present invention generates Continuity Check Message (CCM) frames only when a fault occurs, continues generating CCM frames while the fault remains, and discontinues when the fault clears. The present invention can be utilized with Ethernet Protection Switching to rapidly detect faults. Additionally, the present invention can be used in any Ethernet topology including point-to-point, rings, and the like.
