The Design And Implementation Of Service Quality Analysis Control System In Active Network

Along with the progress and development of computer network in recent years, a variety of computer network related to different types of users of the network needs are constantly changing. Many types of computer network users hope that the relevant information for information transmission of computer network application also Ling Lang everywhere. For all the service network to provide network service quality of Internet users of various computer requirements gradually improved, weakness and defects of the traditional types of existing networks continue to highlight, traditional types of network limits the development of new networks and new type. New active network is to provide direction and opportunity to solve the problems existing in traditional types of network. Active network model consists of model structure of programmable network node. It can support for the network protocol and network development of new services, network authentication and network deployment and other related technologies, and also for network control and management, service quality control, reliable multicast transmission provides a new method.With the application of computer network and the network of continuous development, data message passing between the traditional type of network has been difficult to extend, especially network operation mechanism is almost completely unchanged is the important obstacle data exchange network for development. Many intermediate data packet exchange network(such as in all levels, at all levels of Routers router switch Switchs) with relative past the strong computing ability(the actual transmission time delay and the routing process evaluation operation ability according to the network whole data message "store-forward" process is calculated, but the essence of the data message switching) is passively data transmission; in addition, the update cost high, traditional network operating cycle is longer, which makes the network new protocols and new service is difficult to rapid deployment in a relatively short period of time, this situation has seriously affected the rapid promotion and popularization of new application of computer network.Through in-depth study of the active network theory, and expounds the active network architecture, the active network classification, active network encapsulation protocol, ANEP active network performance and active network system, and then analysis the system demand analysis, system design, system design is described in the quality of service, the analysis of system development platform, J-Sim simulation environment and module design and results. This paper discusses the structure safety and service quality control system in active network in the active network, finally analysis system function realization of active network service quality by using the related network design tools.
