Performance Evaluation for Competing High-Speed TCP Protocols

TCP constitutes the principal protocol of the TCP/IP model transport stack. Today, TCP-Reno is the mainly deployed transport protocol on Internet. It defines a method of controlling congestion in networks with packet switching and particularly the Internet. In spite of the efforts made to resolve the congestion problem, this protocol continues to meet numerous of troubles in particular in networks where the Bandwidth Delay Product (BOP) is high. Mainly, this paper compares the behaviors of the six most distinguished high speed TCP versions using simulations. In particular, it compares the intra protocol fairness of these variants and their behavior in the presence of a standard TCP traffic by examining the resulting unfairness and packet losses.
