Optical repeater, message handling system in point-to-point protocol and processing method

Abstract

The invention discloses optical repeater and method for processing message in PPP protocol. The optical repeater optical reception module, optical gain module and optical transmission module connected in sequence. The optical reception module is also connected to a parsing overhead module in use for obtaining and parsing PPP message. The parsing overhead module is connected to a debugging and outputting module in use for outputting result information of parsing PPP message. The method includes steps: picking up data carried by data communication channel; packaging data into PPP message; parsing PPP message so as to obtain information of parsed result; outputting information of parsed result. The invention also discloses another optical repeater as well as system and method for processing message in PPP protocol. Features are: processing more PPP message without influencing working performance of optical repeater, option for parsing PPP message locally or remotely.

Description

technical field [0001] The invention relates to an optical communication network, in particular to an optical repeater, a point-to-point protocol (Point-to-Point Protocol, PPP) message processing system and a processing method. Background technique [0002] At present, the optical fiber communication network has gradually developed from small capacity to large capacity, from short distance to long distance, from Plesiochronous Digital Hierarchy (PDH) to Synchronous Digital Hierarchy (SDH). Compared with SDH, it adopts new synchronous multiplexing method and flexible mapping structure, unified interface standard, network management ability, strong networking and self-healing ability, good compatibility, advanced pointer adjustment technology, independent virtual container design, series Standard specifications and other advantages, therefore, the application is more extensive. see figure 1 , figure 1 It is a schematic diagram of SDH frame structure, composed of figure 1 I...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to address the defects and deficiencies in the prior art that the processing of all PPP messages cannot be realized, the work performance of the optical transmission equipment is reduced and the PPP messages cannot be remotely analyzed when acquiring and analyzing the PPP messages , providing an optical repeater, a point-to-point protocol message processing system and a processing method, which can obtain PPP messages from the optical transmission link of the optical repeater without affecting the working performance, and according to actual needs Analyze the PPP message in the optical repeater or remotely and output the analysis result information
