摘要
网络仿真技术成为目前研究网络算法、网络协议的一种主要手段。近年来随着网络规模的增大和复杂性的增加对网络仿真模拟器也提出了更高的要求。现有文献提出了很多方法来改进网络仿真平台以适应网络技术的发展。文中主要对一种新的网络仿真模拟器J-Sim的网络仿真原理进行了概述,并从不同的角度对NS-2和J-Sim网络仿真平台进行了对比,最后实例说明了J-Sim仿真的步骤并显示仿真结果。通过对比分析证明J-Sim是一种效率高,易于扩展的网络仿真模拟器,并通过一个实例验证。
The technology of network simulation has become a main method for researching network algorithms and network protocols at present. In recent years, with the increase of network scale and complexity, higher requirements are brought forward to the network simulators. Literatures in existence put forward many schemes for improving the network simulation platform. In this paper, we mainly summarize the principle of a new network simulation platform, called J - Sim, then compare J - Sim with NS - 2 from different aspects. Finally, we elaborate on how we simulate modeling in J - Sim with examples and display the results. Through contrast and analysis, it proves that J - Sim is a network simulator with high efficiency and can be easily extended, and which is validated through an example.
