A Multi-priority Delay Reservation Admission Control Scheme

With the development of differentiated services and multimedia services of network, a multi-priority delay reservation admission control scheme is proposed. In this scheme, different delay threshold of different traffic class is statistically derived. Through computed delay threshold, the admission of different traffic was controlled so as to provide their required service. Numerical results show that either the service of high priority traffic or the service of low priority traffic is guaranteed in the new scheme. The utilization of the network is also promoted
