Abstract
A method and system for transporting traffic having disparate qualities of service classes across a packet-switched network includes receiving at an ingress node of a network a plurality of packets each comprising a quality of service (QoS) class defined externally to the network. Packets having a QoS class comprising delay bound guarantees and a low drop priority are combined into a first internal QoS class. Packets having a QoS class comprising a flexible drop priority and no delay bound guarantees are combined into a second internal QoS class. Packets having a QoS class including no delivery guarantees are combined into a third internal QoS class. The packets are transmitted in the network based on their internal QoS class.
