Abstract

The embodiment of the invention relates to the communication field, especially to a fault processing method and device of an SERDES link group. The objective of the invention is to ensure the work performance of the SERDES link group in the condition of the faults in the SERDES link group. The fault processing method and device of the SERDES link group is suitable for initially configuring N LANEs and an SERDES link groups including (N+M) LANEs, if the K LANEs in the N LANEs are located in the fault state, the K LANEs are determined from the LANEs located in the idle state and the non-fault state, and the K LANEs are arranged at the work state to ensure that there are N LANEs located at the work state and the non-fault state in the SERDES link group in the condition of having faults so as to improve the stability of the SERDES link group.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a fault handling method and a fault handling device for a SERDES link group. Background technique [0002] Serializer / Deserializer (SERializer / DESerializer, referred to as SERDES) is a mainstream time division multiplexing (Time Division Multiplexing, referred to as TDM), point-to-point (peer-to-peer, referred to as P2P) serial communication technology The SERDES link group usually sets a sending channel and a receiving channel between the sending end and the receiving end. A sending channel and a receiving channel are called a channel (called LANE in English). A group of LANEs is called a SERDES chain road group. [0003] Specifically, in each LANE in the SERDES link group, multiple low-speed parallel signals at the sending end are converted into high-speed serial signals, and then transmitted to the receiving end through a transmission medium, such as t...
