Abstract

After system is initialized, electrical interface module of multiplexing 10 / 100 / 1000Mbps Ethernet, or optical interface module of multiplexing 1000Mbps Ethernet, or interface module of multiplexing ATM(over STM-1)PHY module convert data in current network to bus of media flow. Through bus of media flow, kernel process module of network processor extracts data to carry out pretreatment, sends data to switching module of Ethernet. Based on coincidence relation between kernel process module of network processor and module of main processor, the method forwards pretreated data to corresponding module of main processor, and carries out advanced treatment for received pretreated data. Introducing newest network processor to the interface module of monitoring system for communication protocol, the invention raises processing power of interface module, and enhances processing power of main processor module on large volume data through pretreatment on data in current network.

Description

technical field [0001] The invention relates to the technical field of communication protocol monitoring, in particular to a communication protocol monitoring system and method based on a network processor in a communication system. Background technique [0002] In order to monitor the operation quality of the communication network and detect various abnormalities in a timely manner, major domestic telecom operators and communication management bureaus have launched their own communication protocol monitoring systems. The architecture of the communication protocol monitoring system is described in Chinese patent 200410077710.0, Chinese patent 200410096099.6, US patent US6633555, US patent US6501950, and European patent EP1212898A1. [0003] For a communication protocol monitoring system, the existing common practice is to extract the data on the live network through mirroring or high-impedance methods, retain the signaling in it, and hand it over to the server or minicompute...
