虚拟技术和模拟器在网络实验室的应用

摘要

虚拟化技术和模拟器在高校、培训机构的实验室,尤其是网络与信息安全实验室中表现出很多独到的优势。软硬件结合的虚拟化技术能够提供真实性很好的虚拟实验环境,但是需要投入相对较多的人力和物力,而纯软件的模拟器构建的实验环境的真实性表现虽然不是那么优秀,支持的设备也相对较少,但是,极低的投入,甚至无需投入就能让学生拥有自己的实验室,对于高校学生来说已经能够满足绝大多数的实验要求,并且更加易于普及和推广。虚拟化技术虚拟器结合使用的实验教学模式虽然具有很多独到的优势,是未来实验教学的重要途径和方式,目前还取代不了传统的实验教学模式,还有待进一步的成熟和完善。%Virtualization technology has many unique advantages in the laboratories of universities and training institutions,especially in network and information security lab.The combination of the hardware and software of the virtualization technology can provide very good authenticity virtual experimental environment,but need to put in the relatively more human and material resources. Although the authenticity performance of the experimental environment construction by the pure software simulator is not so good,and the equipment is also relatively less supported,very low input,and even does not need the investment can make students have their own lab,it have been able to meet the most experimental requirements for college students,and to be more pervasive and promotion.The experiment teaching mode of virtualization technology and virtual device combination has many special advantages,which is an important way of the future experimental teaching,now also cannot be replaced by the traditional experimental teaching mode,it still need to further mature and improve.
