Improving Start-Up and Steady-State Behavior of TCP in High Bandwidth-Delay Product Networks
Overview It has been long known that the standard Transmission Control Protocol (TCP) yields limited performance in high bandwidth-delay product (BDP) networks due to its conservative Slow Start and Congestion Avoidance algorithms. This paper focuses on TCP modifications to improve both TCP's start-up and steady-state behavior. First, the paper proposes Jump Start, a new technique which has the potential to speedup the start-up of TCP by ignoring the Slow Start. It allows a higher initial sending rate but keeps the remaining of TCP unchanged. Second, EXP-TCP is introduced, a new TCP variant which replaces the additive-increase rule of the Congestion Avoidance with an exponential-increase algorithm. It decouples TCP efficiency control and fairness control to achieve both high performance and good fairness.
