| 摘 要： | 交换结构是高速路由器不可缺少的重要组件,在ns-2中仿真实现交换结构,目标是提供一个具有通用结构和基本功能的交换结构模型.通过队列父类的派生,修改原有的数据结构和分组处理流程,作为标准构件添加到ns-2的构件库中,用户只需在相应的功能函数中添加源代码,就可以开展与交换结构相关的研究工作.仿真结果与理论分析一致,动态跟踪表明开发的交换结构在网络环境中能够准确地转发分组,扩展了ns-2功能进行交换结构网络性能分析.

| Abstract: | Switches are necessary components of high-speed routers.In this paper,the design and implementation of switches in ns-2 are presented.The goal is to implement a model with common structure and functionality of switch.By deriving from a basic class,and modifying the process procedure of packets,switch is implemented as a standard module in ns-2 library.Users can study switch in all kinds of researching areas by coding in relevant functions of the developed switch module.Simulation results are consistent with theoretical conclusions,and dynamic traces show that the developed switch can successfully forward the packets in network environment. |
