一种流媒体拥塞控制算法在NS-2中仿真实现及结果分析

NS(Network Simulator)是一个面向对象的离散事件模拟器,它可以对复杂网络环境中数据传输、拓扑结构设计以及新的路由协议和算法等进行有效模拟和分析。该文首先阐述了NS的体系结构特点及利用NS进行网络仿真的一般方法和步骤,并实现了一种基于流媒体应用的自适应拥塞控制算法的实例,并对其仿真结果进行了分析。实验结果表明,当网络中产生拥塞时,其延迟、时延抖动和吞吐量会发生相应变化的客观现象。

Simulation and Analysis of a Streaming Media Congestion Control Algorithm Based on NS-2

NS （Network Simulator） is an object-oriented visual simulator based on large-scale discrete event.It can simulate and analyze the complex network environment,data transmission,new routing proto- cols and algorithms effectively.This paper describes the architecture and characteristics of NS,and it also gives the technique and the general process based on NS.The instance of a streaming media applications-based adaptive congestion control algorithm is implemented and simulation results are analyzed.The experiment shows that when the network is congested,the delay,delay jitter and throughput will change in an objective Phenomenon.
