 While TCP proxies require such devices to be deployed at both parties of the communication because the protocol running between the proxies is usually proprietary, asymmetric TCP acceleration is able to boost the network performance with unilateral deployment, i.e., only one end of the peers is required to deploy the device or software.Asymmetric TCP acceleration implies the WAN-side protocol has to be TCP of the same 5-tuples and states.The implementations typically terminate the TCP flows on the LAN side like the TCP proxies do.
