Research on QoS Routing in the Internet

With the development of Internet and the constant emergence of all kinds of multimedia business, user´s demand on Quality of Service (QoS) becomes higher and higher. However, the current Internet routing protocol could not provide a good solution for QoS. Quality of service route is at present a very important research topic in the routing protocol, but it is hard to give a perfect method for network. Two factors should be considered in order to implement QoS routing in Internet with balance between economical and technical factors. This paper mainly studies on the technical problems of QoS route and provide an algorithm called SAMCRA to improve the Qos and give some analysis about it.
