Abstract
A method for inverse multiplexing of managed traffic flows over a multi-star switch network includes a source node classifier. The source node classifier, using a traffic-engineering algorithm, classifies incoming traffic based on flow parameters, embeds the flow parameters in a routing table in a node for a flow, places packets from classified flows into Switch-Specific Managed-Traffic Queues (SSMT) and a source node unmanaged traffic queue. A source node switch input scheduler process for a switch selects all managed packets from the SSMT destined for the switch, then selects a single unmanaged packet from the source node unmanaged traffic queue. The source node transmits the packets as classified flows through a switch fabric to the destination node. At the destination node packets transmitted through the switch fabric are sorted by a Switch Output Process and sent to intended output queues.
