The Performance Study of TCP Veno Under Different Recovery Schemes

TCP Veno was recently proposed to eliminate TCP performance suffering in the wireless networks. Real network and live Internet measurements have validated Veno´s significant performance improvement over Reno. In this paper, we revisit Veno´s state distinguishing scheme, and give a detailed study of Veno´s performance when three different recovery schemes: Partial ACK, SACK and PACK, are incorporated. Our network simulation and real testbed results show that Veno´s state distinguishing scheme can make recovery phase more efficient
