Abstract:
1. A method for recognizing offloaded packets in a protocol offload processing system, the method comprising: calculating a common attribute of connection identifications (CIDs) among a plurality of offloaded connections using a common attribute calculating device; recognizing the CID of a packet to determine whether the CID has the common attribute, so as to determine whether the packet is a non-offloaded packet, using a first recognition device; and recognizing whether the packet is an offloaded packet if the CID of the packet has the common attribute, using a second recognition device, wherein during said calculating the common attribute, the common attribute is calculated through performing a bit-wise OR operation among the CIDs of the offloaded connections, and wherein said recognizing to determine whether the packet is a non-offloaded packet comprises
