Method, system and device for implementing forward error correction (FEC) of optical transport network (OTN) back board

Abstract

Disclosed are a method, system and device for the backplane of an Optical Transport Network (OTN) to implement Forward Error Correction (FEC), so as to solve the problems that system resources are wasted and the signal transmission quality cannot be flexibly adjusted when the existing OTN backplane implements the FEC function. When a sending end performs data transmission, it determines a timeslot parameter value according to the number of FEC encoders configured thereby, an OTUk data frame to be sent is divided into corresponding paths of data according to the timeslot parameter value, and the data is sent to each corresponding FEC encoder for encoding; and each path of encoded data is multiplexed into OTUk data frames for transmission according to the determined timeslot parameter value. In the embodiments of the present invention, as the number of FEC encoders can be configured according to the requirement on the signal transmission quality and the number is not less than 1, system resources can be effectively saved and FEC can be flexibly realized according to the requirement on the signal transmission quality.

Description

technical field [0001] The present invention relates to the technical field of communication transmission network, and in particular to a method, system and device for implementing forward error correction (Forward Error Correction, FEC) on an optical transport network (Optical Transport Network, OTN) backplane. Background technique [0002] The OTN is based on the Wavelength Division Multiplexing (WDM) technology, organizes the transport network of the network at the optical layer, and is the backbone transport network in the next generation network. OTN is a new generation of "digital transmission system" and "optical transmission system" regulated by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) through a series of standards such as G.872, G.709, and G.798. OTN will solve the problems of traditional WDM networks, such as weak wavelength / sub-wavelength service scheduling capability, weak networking capability, and weak protectio...
