Research and Implement of the Key Technology for IP QoS Based on Network Processor

Along with the rapid development of network technology, the application of internet is wider. The network service also presents the characteristics of diversification. Thus the traditional real-time services have not already people\´s need. Immediately what to produce is various multi-media businesses such as, video, audio, the television meeting etc. with high request of real time. The traditional service of IP net can provide" do the best one can" only which can not satisfy the request of low time delay. So the trends of IP provide service of classification and guarantee the quality of service in network equipment. The network is developed rapidly, Router is the main network equipment and the control unit is network processor, so the research and implement of the quality of service is important orientation. The principal content of this dissertation is realization of the IP QoS based on network processor. According to the characteristic of network and the performance of network processor, a IP QoS system model is designed. The IP QoS in data transmit lay is mainly researched and realized, the validity of the QoS system proposed in this dissertation of is also proved in Router.
