Abstract:
In a communication system having a plurality of traffic streams, each traffic stream having a target rate and a measured rate, a traffic conditioning method for assigning a drop precedence value to each of a plurality of packets associated with a traffic stream, the drop precedence value equal to one of a first drop precedence value and a second drop precedence value higher than the first drop precedence value, the traffic conditioning method comprising:determining that the measured rate is greater than the target rate; and assigning to each of the plurality of packets a drop precedence value such that, of all packets assigned either the first drop precedence value or the second drop precedence value, substantially (1âˆ’q) of the packets are assigned the first drop precedence value and substantially (q) of the packets are assigned the second drop precedence value, wherein 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.
