Abstract:
1. A method of routing a plurality of data packets through a network, comprising: at an ingress edge unit: determining a set of classification parameters for each of the plurality of data packets arriving at the ingress edge unit, wherein the set of classification parameters includes destination information and one or more quality of service (QoS) parameters for the respective data packet and wherein the destination information includes a destination egress edge unit; and constructing a classification index including the QoS parameters and information about a plurality of queues associated with the QoS parameters; transporting the plurality of data packets and the classification index to the destination egress edge unit; and at the destination egress edge unit, routing each of the plurality of data packets to an associated destination egress port within the destination egress edge unit based on the classification parameters determined at the ingress edge unit and without reclassifying any data packet at the destination egress edge unit.
