With the presentation of background and objectives of IP QoS research, the IP QoS technologies are analyzed on the respects of user traffic control and network service management, and the current status of and problems existed in the research are discussed.

This thesis provides an IP QoS model of converged enterprise/campus network, and expatiates its principles, relevant operation of classifying,queue scheduling,congestion avoiding,priority mapping and policy consistence.

In this paper, we rethink the IP QoS problem from the view of road networks, and put forward that we need an appropriate and statistical IP QoS which can be provided by Internet.

The results demonstrate that they both provide fairness for users with explicit quality of service(QoS) guarantees,but MPF algorithm enhancing capacity achieves higher system throughput compared with MPF scheduler with more flexible parameter setting.

For management telecommunication services,the concept of impersonal degree of telecom services satisfaction is defined based on Qos(quality of service) KPI by using attribute set mathematics theory in the paper.

With the interaction between mobile network and the Internet grows constantly at a high speed,how to provide an efficient Quality of Service(QoS) guarantee scheme between IP(Internet Protocol) network and UMTS (Universal Mobile Telecommunication System) has already become a focus in the field of end-to-end QoS.
