摘　　要：网络模拟器是现代通信网络领域的重要研究工具。文中追踪国际上最新研究进展,从现有网络模拟领域需要解决的问题出发,通过对现有主流网络模拟器进行简要的对比分析,揭示了NS-3产生的技术背景和设计目标,然后详细分析了NS-3的主要技术特点和系统功能,并从内核和组件两个层面剖析NS-3的体系结构,着重分析了NS-3中网络节点(Node)和数据分组(Packet)这两个主要网络模块的组成和作用。论文无论是对网络模拟器本身还是网络技术的研究,均具有较好的理论指导意义和应用参考价值。Network simulator is an important research tool in modern communication networks area. Track the latest research progress of the international community and originate from the existing problems in network simulations. Based on comparative analysis of various mainstream network simulators, revealed the technical background of NS - 3＇ s generation and its design goals firstly, then analyzed the main features and functions of NS- 3 in details, and anatomized the architecture in kernel and component levels. Finally, focused on the composition and functions of the two main network component module which are Node and Packet. The research result is of high theoretical and practical significance on both network simulator itself and the network research technology.
