Embodiment Construction

[0017] Referring to the accompanying drawings, 6802 is a switch that implements the monitoring function. On the 6802, the controlled port group and the monitoring port group are designated. The controlled port group is connected to a hub (HUB) with different types of data packets, and ports 3 and 4 are controlled ports. group (analog Internet data); ports 5, 6, and 7 are monitoring port groups; the data of port 5 is required to be the image of all pop3 data of ports 3 and 4; the data of port 6 is the image of all smtp data of ports 3 and 4 Image; the data on port 7 is the image of all http data on ports 3 and 4.

[0018] At present, the business chip 5690 of BROADCOM Company is used to classify the data packets entering the port through the fast filter processor (FFP) of each port, and redirect each class. According to requirements, it can be classified according to the port number of the TCP connection: the first category is the data packet (POP3) with source or destination p...

Abstract

The invention provides a kind of mass information quick-speed classifications and filter method. The invention includes: allocates the monitoring port group and monitored port group on the exchanger,classifies the data packages of monitored port according to special word in data frame, sets one or several class, each class corresponds the first class net flow with the same special word, sets reorienting action to each class, reorients to some fixed port of monitoring ports, and carries on above setting to the monitored ports. The classification and reorientation of data package may set through fast filter process device of each port.

Description

Technical field [0001] The invention belongs to the field of computer network communication, and in particular relates to a method for high-speed classification and filtering of massive information on a backbone network. Background technique [0002] The Internet has entered a period of rapid development in our country, and network applications such as surfing the web, e-mail, online chat, and e-commerce have increasingly become an important part of people's lives. However, the huge advantages of the Internet also bring about major social security risks. Due to the openness and personalization of Internet information, all kinds of "harmful" information prevalent on the Internet are very harmful to society. If we do not have efficient and powerful monitoring methods in cyberspace, all kinds of bad and reactionary information will spread unscrupulously everywhere. We must use high-tech means to build a security line of defense in cyberspace to ensure the public welfare of ne...
