Abstract: A number of improvements in network adapters that offload protocol processin g from the host processor are provided. Specifically, a mechanism for improvin g connection establishment in a system utilizing an offload network adapter (730) is provided. The connection establishment mechanism provides the abili ty to offload connection establishment (1030) and maintenance of connection sta te information to the offload network adapter (730). As a result of this offloading of connection establishment (1030) and state information maintenance, the number of communications needed between the host system (71 0) and the offload network adapter (730) may be reduced. In addition, offloadin g of these functions to the offload network adapter (730) permits bulk notification of established connections and state information to the host system (710) rather than piecemeal notifications as is present in known computing systems.
