A comparison of TCP unfriendly-region congestion control solutions

Providing effective means of congestion control in high BDP networks represents a complex paradigm facing a variety of challenges. The landscape of such paradigm is complicated considering limited availability of congestion signaling information as well as the diverse range of utilized links including but not limited to wireless and satellite links. In this paper, the results of a performance profiling study of a number of congestion control solutions for high BDP networks is provided. The subjects of interest span over two major categories namely feedback-based congestion control solutions and TCP unfriendly-region congestion control solutions. We discuss the applicability of both types of solutions to the networks of interest and how the utilization of these solutions impacts the operation of such networks.
