Abstract
A method of prioritizing packets for delivery over a transport network, where a guaranteed minimum information rate over the transport network is specified. The method comprises, for each bearer to be injected into the transport network from the mobile network, specifying a bearer information rate and marking packets up to that rate as conformant with the bearer information rate, and marking packets exceeding that rate as non-conformant. Multiple traffic-type streams from the mobile network are converged, each traffic-type stream comprising multiple bearers. Packets of traffic-type streams are inspected to identify packets marked as conformant and non-conformant, and at least a fraction of non-conformant packets are re-marked as conformant if the converged rate of conformant packets is less than said minimum information rate. The transport network prioritizes delivery of packets marked as conformant over those packets marked as non-conformant.
