Research And Realization Based On Many Integrated Services Of The Router To Achieve Packet-Switching Network

In Internet, if we want to have the good service quality of multi-network. The router in IP network must have the ability of different services so as to enable packet switching networks to support real time and interactive communications with guaranteed Quality-of-Services(QoS). This paper is to study and develop some important techniques-traffic characterization, traffic regulation, and packet scheduling based on many classes of service. Firstly, the network resources are usually reserved according to multimedia sources' characteristics; a precise traffic characterization scheme can use valuable network resources efficiently while still maintaining the required QoS. Secondly, it will focus on the design of packet scheduling disciplines, which decide the packet-transmission schedule so as to satisfy different kinds of packet-delay bounds required by those connections sharing a single output port. Finally, experiments and statistics are carried out according to the approach. From the research results, it proposes an end-to-end multimedia connection admission criterion as the complete solution.
