Abstract: In a network environment, a node may measure and/or recognize network activity or congestion and send feedback to downstream nodes (i.e., higher rank nodes) in response. During periods of lower network activity, lower congestion and/or lower network load, the feedback may direct an upstream flow of packets to be transmitted at a quality of service (QoS) level that allows consumption of more bandwidth than is indicated by a QoS level associated with a service level agreement (SLA) of the upstream flow of packets. During periods of higher network activity, congestion and/or network load, the feedback may limit the upstream flow of packets to the QoS level associated with the SLA of the upstream flow of packets. Accordingly, an upstream node (e.g., a root node) may use feedback to regulate bandwidth used by one or more downstream nodes and/or flows of packets, in part using network activity, congestion and/or bandwidth availability.

Abstract: An improved method is described for providing Differentiated Services (Diffserv) traffic to a node in a network that implements a security method that discards duplicate packets received at the node. The method includes the step of identifying at least two service levels to be provided to received traffic and assigning different size look-back window counts to each of the service levels. The look-back window count indicates a number of packets that have been previously received at the node that should be compared against a received packet to determine whether a duplicate packet has been received. In one embodiment, a service level that has higher priority is assigned a lower look-back window count and thus examines fewer previously received packets than a service level having a lower priority. Such an arrangement reduces the possibility that traffic having higher priority is dropped as a security measure.
