| Abstract: | In order to control traffic flow congestion, a Call Admission Control(CAC) strategy for resource partial-shared systems with Variable Bit Rate(VBR) services is proposed. It is dependent on the max bandwith and the expired threshold of the cell loss probability online connections of each type of service. An approach of the call blocking probability and the packet loss probability are presented. The relations between QoS indicators and control parameters used in the strategy are analyzed, and some related conclusions are proved mathematically or numerically. |
