Abstract

In this paper, we propose an improving method for CAC (call admission control) process that could reduce call blocking rate in QoS network, especially in the saturated situation. We modified the proposed CRDM by estimating the call request holding time for an expected new released bandwidth from the traffic descriptor of present active connections. The method performance is shown as simulation results in term of call blocking rate and network utilization ratio which compared among modified CRDM, original CRDM and the traditional CAC on IntServ over DiffServ framework
