The exponential growth of high bandwidth global networks has rapidly exposed the design limitations of the TCP protocol. The congestion avoidance behavior of TCP has been implicated as a likely culprit for poor single-stream TCP throughput on high bandwidth-delay-product networks. The network research community has offered wide range of alternatives to fix TCP's congestion avoidance behavior, but every available technique has focused on high-throughput for bulk flows like file transfers. This paper focuses on the requirements of interactive visualization and control applications that have been neglected in the design of these new protocols.
