TCP acceleration is the name of a series of techniques for achieving better throughput on an Internet connection than standard TCP achieves, without modifying the end applications. It is an alternative or a supplement to TCP tuning. Commonly used approaches include ACK pacing, TCP transparent proxies in two or more middleboxes, and TCP offload engines. TCP transparent proxies involve breaking of long end-to-end control loops to several smaller control loops by intercepting and relaying TCP connections within the network. By adopting this procedure, they allow for the TCP flows to have a shorter reaction time to packet losses which may occur within the network and thus guarantees a higher throughput. The idea of a TCP accelerator is to terminate TCP connections inside the network processor and then relay the data to a second connection toward the end system. The data packets that originate from the sender are buffered at the accelerator node, which is responsible for performing local retransmissions in the event of packet loss.
