摘要
由于网络验证测试构建真实环境的代价较大、性价比低、全虚拟化环境所得结果不够真实,存在一定的局限性,为此提出基于轻量级虚拟化的多尺度网络复现研究方法。利用轻量级虚拟化技术构建开放源代码虚拟机监视器体系,将物理硬件和操作系统分离,统一物理资源,令资源不受物理限制约束,在一个物理机器上同时运转多个不一样的操作系统,并且各个操作系统能够执行多个应用程序,使硬件与操作系统虚拟化。再通过聚类系数、度的分布、平均路径长度、网络时效以及网络质量等网络复现指标,实现多尺度网络复现。实验通过连通性、透明性、并发性指标验证构建的网络,得出所提方法的仿真规模较大,性价比较高、适用性较强,充分验证了上述方法的有效性。
At present, the cost of building a real environment for network verification tests is high, and the cost performance is low. However, the fact that the results obtained in a fully virtualized environment are not enough. Therefore, a research method on multi-scale network replication based on lightweight virtualization was proposed. First, lightweight virtualization technology was used to build an open-source virtual machine monitor system. This system separated the physical hardware from the operating system, so that the resources were not constrained by physical limitations. Different operating systems were run on one physical machine simultaneously, and each operating system would execute multiple applications, so that the hardware and operating system were virtualized. Then, multi-scale network replication was achieved by clustering coefficient, degree distribution, average path length, network efficiency, and network quality. The experiment verified the constructed network through connectivity, transparency, and concurrency indexes. Simulation results prove that the proposed method has a large simulation scale, high-cost performance, and strong applicability.
