Method and system for performing packet integrity operations using a data movement engine

Systems and methods are provided for an improved TCP/UDP checksum method. The checksum methods described herein may be characterized as utilizing the system data movement engine, such as a direct memory access (DMA) engine, as part of the checksum process. The checksum process may be incorporated within the prescribed interface mechanisms utilized to move data across an interconnection medium. In this manner a TCP/UDP checksum process has been provided in which checksum generation is incorporated within the data movement engine utilized with a high speed interconnect medium (for example a switch fabric). Moreover, the checksum process may be split up and different operations performed at different steps of the packet transmission process. Thus, portions of the checksum process may be performed on either side of the interconnect medium during the transmission process.
