Abstract: A method and system for routing traffic in a communication network is disclosed that may include assigning each node in a network a first subset of route repository nodes and a second subset of route repository nodes, querying the second subset of route repository nodes in order to obtain route information that is stored in the second subset of route repository nodes, computing route information by applying a route computation algorithm to the first subset of route repository nodes, and routing traffic in the communication network based on the route information obtained from the second subset of route repository nodes and the route information computed using the first subset of route repository nodes.

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).
