摘要/Abstract

摘要： 协议评估是网络协议设计开发的重要环节,直接影响到协议设计开发的效率和质量。网络模拟、实际测试和网络仿真是3种主要的协议评估途径,网络模拟在真实性上存在明显不足；实际测试不具有可重复性和可控制性；网络仿真兼有两者的优点,又可避开其不足,为协议评估提供低成本、可控制、可重复、高真实度的测试平台。分析了网络模拟、实际测试和网络仿真对协议评估的影响,归纳了网络仿真的分类,重点对参数控制的网络仿真系统设计思想进行了分析,最后对网络仿真的发展趋势进行了展望。

Abstract: Performance evaluation is an important stage during the development of network protocols．Algorithms and Protocols are usually tested in experimental network or simulation environments．Simulation level of abstraction may be too high to capture low-level effects．Experimental networks are neither controllable nor repeatable．Emulation provides a third point for protocol testing and evaluation；it is expected to be a low-cost,controllable and repeatable testing platform with high degree of realism．In this paper,we make a survey on network emulation systems,including their concepts,classification,focus on design methodology of the Virtual Machines and the Resource Mapping emulation system,the developing trends and main challenges are also summarized.

Key words: Network emulation,Protocol evaluation,Design methodology,MANET
