Abstract:

A method and system of congestion control in a network are provided. A required quality of service (QoS) parameter, such as a maximum allowable latency, for a packet received at a queue in the network, and a route cost metric, such as accumulated and estimated latency, are determined, and the packet is either discarded if the route cost metric exceeds the required QoS parameter, or a discard bias value is set for the packet. Also, if the required QoS parameter exceeds the route cost metric, the method includes determining whether a congestion condition exists in the network, and if the congestion condition exists, biasing the packet for discard based on its latency if the route cost metric for the packet exceeds a threshold. The network may be an IP network, and a network such as a mobile ad hoc network (MANET).
