一种改进的高速TCP拥塞控制机制

An Improved High Speed TCP Congestion Control Mechanism

对现代高速网络中,传统TCP拥塞控制机制的窗口速率波动较大和对长时延链接歧视导致的不公平问题,基于合理划分网络负载状态、动态调整拥塞周期个数和拥塞窗口大小的策略,提出了一种自适应的高速网络拥塞控制方案,并使用网络仿真软件对控制算法进行了仿真。

In modern high speed network,the conventional TCP congestion control mechanism leads to high data-rate changing and has strong bias against links with higher round-trip delays.This paper proposes a self-adaptive congestion control mechanism through the method that divides network into different states and dynamically adjusts the numbers of congestion epoch and the size of congestion window.The algorithm is simulated through the software of network simulator.
