在高速广域网络中，由于拥塞窗口较大，拥塞控制响应速度较慢，导致拥塞控制性能较差。任何替代协议都面临的挑战是以简单而稳健的方式更好地利用具有高带宽延迟产品的网络，而不会与现有流量产生不良交互。可扩展的tcp是对tcp拥塞窗口更新算法的简单改变。它提供了一种健壮的机制来提高使用传统的TCP接收器的高速广域网络的性能。可扩展的TCP设计为可增量部署，当小窗口足够时，其行为与传统的TCP堆栈相同。通过在Linux操作系统和千兆位跨大西洋网络上使用可伸缩的TCP实现收集的实验结果来评估该方案的性能。收集的初步结果表明，部署可扩展的TCP在提高高速广域网中的批量传输性能的同时，对现有网络流量的影响可以忽略不计。
TCP congestion control can perform badly in highspeed wide area networks because of its slow response with large congestion windows. The challenge for any alternative protocol is to better utilize networks with high bandwidth-delay products in a simple and robust manner without interacting badly with existing traffic. Scalable TCP is a simple sender-side alteration to the TCP congestion window update algorithm. It offers a robust mechanism to improve performance in highspeed wide area networks using traditional TCP receivers. Scalable TCP is designed to be incrementally deployable and behaves identically to traditional TCP stacks when small windows are sufficient. The performance of the scheme is evaluated through experimental results gathered using a Scalable TCP implementation for the Linux operating system and a gigabit transatlantic network. The preliminary results gathered suggest that the deployment of Scalable TCP would have negligible impact on existing network traffic at the same time as improving bulk transfer performance in highspeed wide area networks.
