摘要:
 计算机仿真已经成为研究计算机网络的重要手段。随着现代网络的规模和复杂度不断扩大,利用有限的资源来仿真大规模网络的需求越来越迫切。文中介绍了网络仿真的常用软件NS、OPNET、CORE,并特别分析了支持软件定义网络SDN的Mininet等新型网络仿真软件,探讨了关键的网络仿真技术,从软件体系结构、软件技术方面对这些软件和技术进行了分析,并对各自的优缺点进行了简单比较：NS开源免费；OPNET用户界面友好,但价格昂贵；CORE不仅开源免费,更因为可以与真实设备结合使用,所以相对NS和OPNET具有更高的真实性；Mininet则更适应于软件定义网络的仿真。
Abstract:
 Computer emulation has become one of the significant means for studying computer networks. As the scale and complexity of modern network constantly increases,the requirement for large-scale emulation,with limited resources,becomes more and more urgent. In this paper,introduce NS,OPNET,CORE,what are used in network emulation frequently,especially analyzing Mininet-a new type soft-ware for software-defined networks,discuss the critical network emulation technologies,analyze them by the aspects of software system architecture and software technologies,and make a simple comparison for their advantages and disadvantages. NS is open-source and free. OPNET has a good user-friendliness,but the price is expensive. CORE is not only open-source and free,but also can combine with the real equipment,so it is more realistic than NS and OPNET. Mininet is more suitable for emulation of software-defined networks.
