Abstract :
TCP Veno was recently proposed to eliminate TCP performance suffering from wireless links. Real network measurements and live Internet results have validated Veno´s significant throughput improvement in wireless networks and its harmonious coexistent behavior with TCP Reno connections in wired networks. In this paper, we study Veno´s performance in asymmetric networks such as ADSL, HFC, where network congestion occurs on the reverse path of acks rather than on the forward path of data sending. Our real experiments demonstrate that Veno continues to reach higher throughput in these asymmetric networks, regardless of wireless or wire links being embedded. Throughput improvement up to 88% over Reno is reached.
