摘　　要：随着高速网络的发展,标准TCP的控制方法已经不能适应其发展要求。由于高速网络具有高带宽-延时积的特点,标准TCP的控制机制在高速网络中对拥塞窗口有严重的限制,影响了高速网络的性能。文中结合高速网络的特点,通过源节点基本控制技术、TCP稳态模型分析研究了原有的TCP传输控制技术。最后研究和分析了近年来提出的高速网络传输控制协议。With the development of high-speed networks ,the control methods of current Standard TCP have not adapt to the demand of it. The control mechanisms of the current Standard TCP constrains the congestion windows because of the characteristic of high bandwidth-delay product in high-speed networks, which influences the performance of high-speed networks. The current control technologies is researched by combining the characteristic of high- speed networks with the technique in source node, the analysis of the steady-state model of TCP. And then the transport control protocols proposed in recent years for high-speed networks are studied and analyzed.
