Title: COMMUNICATION FAILURE RECOVERY METHOD AND FIRST COMMUNICATION NETWORK ELEMENT
Abstract:
Disclosed in the embodiments of the present application are a communication failure recovery method and a first communication network element, for improving the reliability of optical fiber communications. The method of the embodiments of the present application comprises: when a first communication network element detects that the receiving path of a first channel has been communicatively interrupted, the first communication network element determining to use the transmission path of the first channel and the transmission path of a second channel to perform data transmission, and determining to use the receiving path of the second channel to perform data reception; when the receiving path of the first channel is recovered from being communicatively interrupted to being communicatively normal, the first communication network element does not change the data receiving and transmission paths, so that the first communication network element still uses the receiving and transmission paths determined when the receiving path of the first channel has been communicatively interrupted, to perform data transmission and reception.
