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 method and device for synchronizing a forward error correction encoding and decoding mode, including encapsulating the forward error correction synchronization mechanism and / or synchronization control parameters supported by the local network equipment into self-negotiated transmission parameters; The end network device performs self-negotiation communication, and determines the forward error correction synchronization mechanism and / or synchronization control parameters supported by the local network device and the peer network device; detects the reception according to the determined forward error correction synchronization mechanism and / or synchronization control parameters and establish synchronization, or send data for synchronous detection to the peer network device according to the determined forward error correction synchronization mechanism and / or synchronization control parameters. By encapsulating the forward error correction synchronization mechanism and / or synchronization control parameters supported by the local network equipment into the self-negotiation transmission parameters, the present invention improves the flexibility of FEC synchronization control, shortens the establishment time of FEC synchronization, and improves the data transmission efficiency. transmission efficiency.

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...
