TCP Veno is a novel end-to-end congestion control scheme which can improve TCP performance quite significantly over heterogeneous networks, particularly when wireless links form part of such networks. The key innovation in Veno is the enhancement of Reno congestion control algorithm by using the estimated state of a connection based on Vegas. This scheme significantly reduces "blind" reduction of TCP window regardless of the cause of packet loss. The salient feature of TCP Veno is that it only needs simple modification at sender side of Reno protocol stack. Considering practical issues ¨C deployability and compatibility (conformance with legacy connections), Veno TCP may be quickly deployed in "hot" Mobile Internet industry.

TFRC Veno is a milestone work of TCP Veno. TFRC Veno makes use of the Veno equation to successfully solve TFRC wireless suffering problem with the 300% improvement over TFRC at 10% loss rate.  TFRC Veno also inherits the desirable features of TFRC, namely good fairness, nice TCP-friendliness and smoothness of sending rate. Like TCP Veno, TFRC Veno only needs to modify the sender-side protocol of TFRC while the receiver-side or intermediate node protocol stack remains intact.
