TCP Westwood+ Enhancement in High-Speed Long-Distance Networks
White Papers In this paper, mechanisms to enhance the performance of TCP Westwood+ in the presence of a large Bandwidth-Delay Product are studied. In particular, the employment of a logarithmic function for congestion window increase in the absence of packet...

TCP End-to-End Performance Improvement Over Wireless Networks Via Early Packet Loss Recovery
White Papers A new technique is proposed that enables TCP to early detect packet losses, which cannot be detected and retransmitted using the standard fast retransmit mechanism, and to quickly retransmit those packets without waiting for a timeout to occur...

TCP With Header Checksum Option for Wireless Links: An Analytical Approach Towards Performance Evaluation
White Papers TCP performs poorly in wireless mobile networks due to large bit error rates. Basically, the TCP sender responds to these losses as if they were due to congestion in the network, and reduces the congestion window unnecessarily.

TCP's Protocol Radius: The Distance Where Timers Prevent Communication
White Papers This paper examines how the design of the Transmission Control Protocol (TCP) implicitly presumes a limited range of path delays and distances between communicating endpoints. It shows that TCP is less suited to larger delays due to the interaction...
