拥塞网络环境下两种典型的TCP算法仿真比较研究
|
摘要
拥塞控制已成为网络能否有效可靠运行的关键技术,而基于TCP的Reno和Vegas算法是网络拥塞控制中的两种典型算法,通过NS2仿真平台,对两种算法进行模拟仿真,在拥塞网络环境下,比较两种算法的cwnd变化、封包丢失率及平均吞吐量,从而得出在简单网络中,Vegas算法性能更好。
Congestion control has become a key technology for the effective and reliable operation of the network.TCP-Based Reno and Vegas algorithms are two typical ones in network congestion control. We had a simulation with NS2 network simulator on Reno and Vegas under a congested network environment, the performance of the Vegas algorithm is better in a simple network by comparing the cwnd, packet loss, and average throughput of the two algorithms.
