Abstract

The invention discloses a method and device for processing optical transmission frame overhead, which are used for solving the problem of lower processing efficiency of overhead data of n paths of optical transmission frames in the prior art. The device comprises an overhead extracting module, a programmable logical device and an overhead insertion module, wherein the overhead extracting module is used for extracting overhead data of the optical transmission frames; the programmable logical device is used for performing overhead processing on the extracted overhead data; and the overhead insertion module is used for inserting processed overhead data into the optical transmission frames. The extracted overhead data are subjected to overhead processing by adopting the programmable logical device, so that the processing efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a processing method and device for optical transmission frame overhead. Background technique [0002] The overhead data of the optical transmission frame contains a large amount of data description and control information. The specific frame structure is as follows: figure 1 As shown, it includes overhead 1, overhead 2, overhead 3, . When the optical transmission frame is transmitted, it is often necessary to perform complicated processing on the overhead data in the optical transmission frame. For different application environments, the specific processing process of frame overhead is very different. The common processing method is to use the CPU and registers to read overhead data asynchronously, and complete the data exchange between the overhead processing logic and the chip. Although this method can complete the processing of overhead data of n-way (n is ...
