Embodiment Construction
[0026] figure 2 It is a flow chart of Embodiment 1 of the fault handling method of the present invention, as figure 2 As shown, this embodiment provides a fault handling method, which may specifically include the following steps:
[0027] Step 201, receiving a fault event reported by the first linkage module after detecting a fault in the main pseudowire PW between the local device and the remote device.
[0028] In order to solve the problem that when the link on the local device side fails, the remote device cannot detect the fault and still transmits data through the faulty link. In this embodiment, BFD and Ethernet in the first mile (Ethernet in The First Mile (hereinafter referred to as: EFM) linkage technology, so that the remote device can be notified of the fault event in time when the local device side fails. In this embodiment, the local device and the remote device are a relative concept, and this embodiment can also adopt figure 1 In the application scenario s...
