Abstract

In this paper, we present a novel congestion control algorithm for the Transmission Control Protocol (TCP) for the future Internet. Our assumption of future Internet is that, with the increasing quality of service (QoS) requirements, per-flow packet scheduling (per-flow here refers to per TCP or UDP connection) will replace the current first-come-first-serve algorithm used in routers. Based on the assumption, we design a new congestion control algorithm. In our TCP-CC algorithm, each connection adjusts the size of the congestion window according to the size of its packet queue at the bottleneck router. Thus, the queue size for each connection at the bottleneck router is within a controlled range. We show that congestion loss is effectively reduced compared to the current TCP congestion algorithm.
