Abstract

The invention discloses a P2P (peer-to-peer) traffic identification and monitoring system based on a multi-dimensional vector machine, and relates to the field of P2P traffic identification and monitoring. The system comprises a P2P traffic identification module based on an SVM (support vector machine), a P2P traffic monitoring administration module based on the SVM and a traffic control module. The system can provide a fine man-machine interaction interface, helps a network administrator to more effectively know and administrate network resources, adjusts a corresponding P2P traffic identification mode and a P2P traffic control mode according to an administration strategy, can also provide backup cache for hot files, and releases traffic pressure of a key link.

Description

The identification of P2P flow and supervisory control system based on the multi-C vector machine

Technical field

The present invention relates to the identification of P2P flow and supervisory control system, relate in particular to the identification of P2P flow and supervisory control system based on the multi-C vector machine.

Background technology

Along with the development of network, P2P network technology of new generation is widely used.The P2P of current popular uses and mainly comprises file-sharing, P2P streaming media video and instant messaging etc.In the time of P2P technology development, various P2P use the network traffic data that produces and have surpassed traditional Network, HTTP and FTP account for more than 80% of whole Internet flow, become the maximum consumer of the network bandwidth, bring white elephant to network, brought huge challenge also for each the large management P2P of operator flow.The Internet massive band width is used by P2P and is occupied, service quality to other application has formed threat, has also damaged Internet Service Provider's interests, for the operation that guarantees that network is can be normally orderly, be necessary the P2P network traffics are identified and monitored, improve the performance of network service.

Summary of the invention

The identification of P2P flow and the supervisory control system based on the multi-C vector machine of the present invention's invention, comprise with lower module: based on the P2P flow identification module of SVM, be used for finishing separation identification by the control of strategy controller, this module comprises protocal analysis layer, flow identification layer and IP feedback layer, described protocal analysis layer is used for the analysis to each layer protocol, and the protocol analysis to TCP/IP is provided; Described flow identification layer is used for providing the function of comprehensive flow identification by the service traffics identification engine based on statistical property and multi-C vector machine; Described IP feedback layer is used for depositing IP address and the corresponding agreement of the P2P flow that has identified;

P2P traffic monitoring administration module based on SVM, being used for offering help, network manager is understood and the man-machine interaction page of network resource administration, simultaneously according to management strategy adjustment corresponding P2P flow RM and P2P flow control mode, this module comprises monitor, taximeter and strategy controller, and described monitor is used for being responsible for providing flow monitoring data and form; Described taximeter is used for being responsible for control and processes charge information; Described strategy controller is used for being responsible for formulation and the change of flow control strategy;

Flow-control module, be used for being responsible for the execution of P2P flow control strategy and be responsible for collecting flow use information, this information of buffer memory also is reported to P2P traffic monitoring administration module based on SVM, and this module comprises the content caching device, is used for providing content-based network cache function.

This system can effectively realize identification and the monitoring to the P2P flow.
