摘要

The network replication technology has become the cornerstone of the evaluation platform for network security experiments and the system for network emulation.Facing the requirements of fidelity and scalability of network replication,a multi-scale network replication technology based on cloud platform for the fusion of lightweight virtualization,full virtualization and digital simulation was proposed.The architecture of the seamless fusion of these three scales was introduced at the beginning;And then the network construction technology based on the architecture was studied.The emulation experimental results show that the emulation network which is built with the construction technology has the characteristics of flexibility,transparency and concurrency;in addition,the construction technology is capable of emulating networks with high extensibility.At last,communication tests for a variety of protocols and simple network security experiments on the large-scale emulation network were conducted to verify the availability of this large-scale emulation network.The extensive experimental results show that the multi-scale network replication technology for the fusion of virtualization and digital simulation can be used as the powerful support for creating large-scale emulation networks.%网络复现技术是面向网络安全实验的效果评估平台与网络仿真系统的基石.针对网络复现的逼真性与可伸缩性需求,提出一种基于云平台的轻量级虚拟化、全虚拟化与数字仿真三种尺度融合的多尺度网络复现技术.首先介绍了面向三种尺度无缝融合的网络复现体系架构,然后重点研究了基于该体系架构的网络构建技术.仿真实验结果表明,三种尺度无缝融合的网络构建技术所复现的仿真网络具有灵活、透明、并发的特点;此外,通过该技术所复现的仿真网络还具有高度可扩展性;最后,在所复现的大规模仿真网络上进行多种协议通信测试与简单网络安全实验,验证了该大规模仿真网络的实用性.实验验证结果表明,虚拟化与数字仿真融合的多尺度网络复现技术可作为创建大规模仿真网络的技术支撑.
