Abstract
Systems, apparatusses, and methods are disclosed for transmission control protocol (TCP) segmentation offload (TSO). A hardware TSO engine is capable of handling segmentation of data packets and consequent header field mutation of hundreds of flows simultaneously. The TSO engine generates data pointers in order to 'cut up' the payload data of a data packet, thereby creating multiple TCP segments. Once the data of the data packet has been fetched, the TSO engine 'packs' the potentially-scattered chunks of data into TCP segments, and recalculates each TCP segment's internet protocol (IP) length, IP identification (ID), IP checksum, TCP sequence number, and TCP checksum, as well as modifies the TCP flags. The TSO engine is able to rapidly switch contexts, and share the control logic amongst all flows.
