Abstract: A system and method for protocol independent receive side scaling (RSS) includes storing a plurality of RSS hash M-tuple definitions, each definition corresponding to one of a set of possible protocol header combinations for routing an incoming packet, the set of possible protocol header combinations being modifiable to include later-developed protocols. Based on initial bytes of the incoming packet, a pattern of protocol headers is detected, and used to select one of the plurality of RSS hash M-tuple definitions. The selected RSS hash M-tuple definition is applied as a protocol-independent arbitrary set of bits to the headers of the incoming packet to form a RSS hash M-tuple vector, which is used to compute a RSS hash. Based on the RSS hash, a particular queue is selected from a set of destination queues identified for the packet, and the packet is delivered to the selected particular queue.

Abstract: A system and method for protocol independent multi-flow table routing includes a first flow table, a second flow table, and a shared hash table accessible by both the first flow table and the second flow table. Upon receipt of a packet, a first secure signature of a first lookup key is generated for the first flow table, and a second secure signature of a second lookup key is generated for the second flow table. The shared hash table stores both the first secure signature in association with a first value corresponding to the first secure signature, and the second secure signature along with a second value corresponding to the second secure signature. The first and second values indicate destination information for the packet.
