Abstract
A system that includes a host including at least one per-connection data structure and at least one per-processor data structure, wherein the at least one per-connection data structure is associated with a connection, and an offload engine operatively connected to the host. The engine includes offload engine connection registers and functionality to update the at least one per-connection data structures in the host, wherein the offload engine is configured to send and receive network data on the connection, wherein the host and the offload engine communicate using the at least one per-processor data structure, and wherein the offload engine communicates a status of the connection to the host using the offload engine connection registers.
