 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.Thus, in case of losses, the feedback loop between the sender and the receiver is shortened to the one between the acceleration node and the receiver which guarantees a faster delivery of data to the receiver.
