摘要
TCP (transmission control protocol,传输控制协议)拥塞控制是保证网络中数据畅通的关键机制之一。拥塞控制算法用于同步输入速率(发送速率)和接收速率。输入速率是数据包从发送方发送到接收方的速率,而接收速率是数据包从接收方接收的速率。拥塞控制算法使用窗口大小来同步发送速率和接收速率。网络模拟器-3 (ns-3)是一种流行的工具,用于评估现有的TCP拥塞控制算法,以更深入地了解TCP拥塞控制算法。这有助于开发一种新的算法。我们对各种拥塞控制算法(即New Reno, Veno, BIC, CUBIC和Westwood)进行了窗口大小的比较研究。我们还使用ns-3分析了这些算法的吞吐量。
A Comparative Performance Analysis of TCP Congestion Control Algorithms: Newreno, Westwood, Veno, BIC, and Cubic
The transmission control protocol (TCP) congestion control is one of the key mechanisms that ensure the smooth flow of the data in the networks. The congestion control algorithm is used to synchronize the input rate (sending rate) with a receiving rate. The input rate is the rate at which packets are sent from sender to receiver while the receiving rate is the rate at which packets are received at the receiver. The congestion control algorithm uses window size to synchronize the sending rate and receiving rate. A network simulator-3 (ns-3) is a popular tool used to evaluate the existing TCP congestion control algorithms to know more insight about the TCP congestion control algorithms. That helps to develop a new algorithm. We have carried out a comparative study window size for various congestion control algorithms viz., New Reno, Veno, BIC, CUBIC and Westwood. We have also analyzed these algorithms for throughput using ns-3.
