摘要
A method and system for call admission and preemption in a network having an ingress node and an egress node defining an ingress/egress node pair, and one or more core nodes located in a path between the ingress node and the egress node and configured to mark packets exceeding an admission threshold. The method includes calculating a sustainable preemption rate based on a rate of traffic received at the egress node from the ingress node that passed through the one or more core nodes without being marked, and a ratio between a preemption threshold and the admission threshold. If a traffic load to the egress node is greater than the sustainable preemption rate, at least some traffic is dropped so that the traffic load does not exceed the sustainable preemption rate for the ingress/egress node pair.
