METHOD AND APPARATUS OF ETHERNET DEVICE LINK FAULT DETECTION

摘要

A method and apparatus of Ethernet device link fault detection, the method including the following steps: generating a fault message having the target MEP information after detecting the link fault with the target MEP; sending the fault message. Using the technical scheme, the detection problem of the device link fault of the P2MP group network or the group network having more than two MEP nodes within the MA is solved, which link of many link faults in the P2MP occurring fault can be accurately determined, and the cooperation problem between various detection methods is solved, the fault detection and fault orientation of the whole network of end to end is solved by the cooperation between various detection methods.
