Research And Implementation Of IP Network Quality Of Service Technology

Nowadays, with the development of Internet, the number of user and the size of network are getting larger and larger. Because the use of network becomes wider and wider and the network traffic is larger and larger, people request network communication has a high level quality. The rapid development of the communication network and the increasing popularization of service level agreement(SLA)make it possible that we transmit real-time service in the connectionless IP packet network. Many international organizations, communication equipment producers and service providers are researching and implementing the way to improve IP quality of service(QoS) . Now IP QoS has became one of the focus of IP network researching field.This article's focus is how to improve IP QoS. Integrated services model, differentiated services model and multi-protocol lable switch are analyzed in detail. Comparably, we promote a total solution of 1000M network QoS management system based on differentiated services model. And an implementation based on BMC1250 integrated chip multi-processor hardware platform and Montavista Linux OS.The first part of this paper gives a brief survey on the tendency of the Internet based on IP and introduces he author's main work during the study. Chapter 2 gives the basic concept of QoS, and gives a detailed discussion about several kinds of QoS solutions. Chapter 3 gives overall project design of network QoS management system. Chapter 4 gives the design and implementation of bandwidth management subsystem in detail. At last the author introduces the design of management platform briefly.
