The Study About The Trustworthy Network Traffic Management Based On Service-Awaring Technology

With the continuous development of network technology, Internet increasingly present its character which is complex and isomerous,network security technology present its disordered and dispersed state. Supplying systematic and trustworthy services is the trend of the network study. Comparing with the traditional netwoek,the trustworthy network is a kind of network whose behaviors and results can be predicted and managed by users. In the interest of increasing the manageability and controllability of network, this article researches about the traffic identification and route technique in trustworthy network.In this article, the author does research on traffic management in trustworthy network based on Service-Awaring Technology. In the first part of this essay, it analyzes and compares some existing traffic identification technologies, then combines NN(nerve network) and the traffic identification technology based on traffic behavior character, designed new traffic identification technology which is based on CPSO-BP, another is based on FNN.With this presupposition, this article does research Service-Awaring model frame, and designed the operational flow of its core layer, traffic identification layer. This layer adopt the new traffic identification method, which classify all network traffic to two or three class, such as p2p,general traffic or abnormal traffic, then do the fine granularity classification by general identification method. In the last part, it provides the general frame of trustworthy network management system based on Service-Awaring Technology. This article expounded two important module detailedly,which are Service-Awaring module and traffic control module, provides the implementation results of this system and makes a forecast to the next step.
