Two factors limit the starting an undertaking in market way,one is the insufficient finance support for the lag of capital market,the other is the high cost of the service industry of low level.

Realization of traffic shaper in ATM tester;

β-cascades process and its application in traffic modeling of communication networks;

Aiming at the burst capability in both extent and time, the article proposed a model for network heavy-traffic approximation, based on α-stable self-similar processes, which integrates stable distributing and Gauss self-similar distributing.

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.
