Claim:
A method for use in a packet network that carries at least two traffic classes, the method comprising selecting individually for each link of a plurality of links of said network a particular desired mix of the average rates of traffic among the traffic classes on that link during times of network congestion, and configuring parameters within said network in such a way that said mix of average traffic rates is substantially achieved, wherein said mix of average traffic rates is selected in such a way as to achieve a desired set of packet loss criteria for said traffic classes on said each link, wherein said set of packet loss criteria further includes a maximum desired packet loss ratio of a first one of said traffic classes, and wherein said set of packet loss criteria includes a desired maximum value, during periods of congestion over said each link, of a quantity that is a function of a) a packet loss ratio of a second one of said traffic classes and b) a packet loss ratio of a third one of said traffic classes.
