Method and system for quality of service (QoS) support in a packet-switched network
First Claim
1. A method for transporting traffic having disparate qualities of service across a packet-switch network, comprising:
- receiving at an ingress point of a network a plurality of packets each comprising a quality of service (QoS) class defined externally to the network;
combining packets having a QoS class comprising delay bound guarantees and a low drop priority into a first internal QoS class;
combining packets having a QoS class comprising a flexible drop priority and no delay bound guarantees into a second internal QoS class;
combining packets having a QoS class comprising no delivery guarantees into a third internal QoS class; and
transporting the packets through the network based on their internal QoS classes.

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.

19. A system for transporting traffic having disparate qualities of service across a packet-switch network, comprising:
-
logic encoded in media; and the logic operable to receive at an ingress point of a network a plurality of packets each comprising a quality of service (QoS) class defined externally to the network, to combine packets having a QoS class comprising delay-bound guarantees and a low drop priority into a first internal QoS class, to combine packets having a QoS class comprising a flexible drop priority and no delay bound into a second internal QoS class, and to combine packets having a QoS class comprising no delivery guarantees into a third internal QoS class initiating the transport of the packets through the network based on their internal QoS classes.

20. A local interface for a packet-switched network node, comprising:
-
a port operable to receive a plurality of packets each comprising a quality of service (QoS) class defined externally to a network of the node and to combined packets having QoS classes comprising delay-bound guarantees and a low drop priority into a first internal QoS class, to combine packets having a QoS class comprising a flexible-drop priority and no delay bound guarantees into a second internal QoS class and to combine packets having a QoS class comprising no delivery guarantees into a third QoS class and to buffer the packets in buffers corresponding to their internal QoS classes; and a scheduler operable to schedule transmission of the packets out of the buffers for transmission over the network based on their internal QoS class.
