Abstract
Certain embodiments of the invention may be found in a method and system for multi-layer network interface controller (NIC) operation. An aspect of the invention may utilize a two (2) level work-conserving scheduling system for network interface controller operation and may comprise tracking for all L4/L5 offload connections with active transmit requirements as well as layer 2 (L2) level transmit requirements. The first level may comprise a round-robin scheme that may be utilized to select the next high priority, normal priority, and layer 2 (L2) transmit requirement independently. The send level arbitration may comprise a work-conserving programmable weighted round-robin priority scheme that may be utilized to select amongst the transmit tasks selected by the first level priority scheme.
