Serial accessing high speed backbone network traffic acquisition and monitoring method

Abstract

The invention discloses a serial accessing high speed backbone network traffic acquisition and monitoring method, which aims to overcome the shortcoming that network traffic cannot be controlled in real time by conventional monitoring methods. The technical scheme comprises the following steps of: improving an input card, and setting a message replication module, a serial processing channel and asecond sampling module in the input card, wherein the serial processing module consists of a stream module and a first sampling module, and the stream module determines the message blocking, total output or sampling output of a certain stream; modifying an input card initialization program of control software in a switching control card, and initializing all cards in a traffic acquisition and monitoring system by using the program; and acquiring and monitoring core backbone network traffic by using the input card. By the method for acquiring and monitoring the network traffic cooperatively bythe serial processing channel and a parallel processing channel, the network traffic can be controlled in real time, traffic control rules can be uploaded in real time and information junks can be prevented from being propagated instantly when discovered.

Description

technical field [0001] The invention relates to a flow collection and monitoring method of a high-speed backbone network. Background technique [0002] The role of high-speed network traffic collection and monitoring is to filter, collect, supervise and manage data on high-speed network links, and can be applied to data monitoring of metropolitan area networks and national backbone networks, and high-speed access flow control of large-scale enterprise networks Wait. At present, although the high-speed backbone network traffic collection and monitoring products on the market are different in performance and supported access rate, they are all connected in parallel (also called side connection) to the high-speed backbone network in the way of optical splitter splitting. Traffic collection and monitoring The system is equivalent to a parallel processing system of the high-speed backbone network. Most of the structures of these high-speed backbone network traffic collection an...
