ABSTRACT:
System for bandwidth assignment to manage congestion over a network bottleneck, comprises a regulation point being set up downstream of the bottleneck in the network to manage congestion in data packets arriving from various sources via the bottleneck. For each of the sources, a priority level assigner assigns priority levels to respective data packets. A token bucket assigns tokens at a limiting rate to the prioritized data packets, the tokens allowing passage of packets to which they are assigned. The token bucket is a multi-priority token bucket, meaning it has at least two thresholds corresponding to the priority levels assigned to the packets. The token bucket only assigns a token to an arriving packet having a respective priority level if there are sufficient tokens currently in the bucket to reach the threshold corresponding to the packet's priority level.
