TCP acceleration is the name of a series of techniques for achieving better throughput on a network connection than standard TCP achieves, without modifying the end applications. It is an alternative or a supplement to TCP tuning.

It is an alternative or a supplement to TCP tuning. Commonly used approaches include checksum offloading, TCP segmentation and reassembly offloading, DMA offloading, ACK pacing, TCP transparent proxies in two or more middleboxes, and TCP offload engines.
