A bandwidth allocation system, device, and method for assigning a drop precedence value to each of a plurality of packets associated with a traffic stream having a target rate and a measured rate greater than the target rate assigns a drop precedence value to each of a plurality of packets associated with the traffic stream such that, of all packets assigned either a first drop precedence value or a second drop precedence value higher than the first drop precedence value, substantially (1-q) of the packets are assigned the first drop precedence value and substantially (q) of the packets are assigned the second drop precedence value, where q is equal to the ratio of a minimum target rate from among a plurality of traffic streams to the target rate of the traffic stream. Such a packet marking scheme may be used in a differentiate services communication system for proportionally distributing excess bandwidth between multiple traffic streams.
