Serial accessing high speed backbone network traffic acquisition and monitoring method

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.
