Problems solved by technology

Therefore, the synchronization process on the existing FEC decoding side takes a long time, and more data needs to be discarded, which reduces the transmission efficiency of the communication link
In addition, the number of code block detections in the existing CRC check mode is fixed, and the flexibility is insufficient

Abstract

The invention discloses a synchronization method and device for an FEC (Forward Error Correction) encoding and decoding mode. The synchronization method comprises the following steps: encapsulating anFEC synchronization mechanism and / or a synchronization control parameter supported by local network equipment into a self-negotiating transmission parameter; performing self-negotiating communicationwith opposite-end network equipment, and determining an FEC synchronization mechanism and / or a synchronization control parameter supported by the local network equipment and the opposite-end networkequipment; and detecting received data according to the determined FEC synchronization mechanism and / or the synchronization control parameter and synchronizing the data, or transmitting data for synchronization detection by the opposite-end network equipment according to the determined FEC synchronization mechanism and / or the synchronization control parameters. According to the synchronization method of encapsulating the FEC synchronization mechanism and / or the synchronization control parameter supported by the local network equipment into the self-negotiating transmission parameter, the flexibility of FEC synchronization control is improved, the FEC synchronization establishment time is shortened, and the data transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for synchronizing a forward error correction codec mode. Background technique [0002] Forward Error Correction (FEC) technology means that the signal is pre-encoded before being sent to the transmission channel, adding redundant code with signal characteristics, and decoding the received signal according to the corresponding algorithm at the receiving end, so as to find It is a technology to output and correct error codes generated during transmission. The main features of FEC are: no feedback channel, fixed decoding delay, more suitable for real-time business transmission system. The application of FEC coding and decoding technology in optical communication system can effectively reduce the bit error rate of the system with a small redundancy cost, extend the transmission distance and reduce the system cost. [0003] The synchronization proc...
