The Research And Implamentation Of Dynamically Configurable Virtual Network Technology In Cyber Range

To build a large Cyber Range has important significance for the safty of the country and it will make us in an advantageous position in the network war.Cyber Range involve the technology to build large testbed(such as virtualizetion and simulation),network flux,modeling of experiment,arsenal of network attack,management of experiment,collect and parse of the data and so many other complex technology,and it is a absolute complex system.The Implementation of Cyber Range provides real and effective environment for network security technology research and offensive and defensive drills.The main objective of this thesis is how to build a virtual network in Cyber Range,and propose to adjust the resource in the whole experiment by flexibility of virtual network.Major jobs are summarized as follows:First,studied the basic technology and deployment of CloudStack,and compared with OpenStack,to make sure that CloudStack are suitable for Cyber Range as the basis platform.Then,analyzed NS2 and OPNET,and used them to make the node simulate model library for flexibility adjustment.This thesis put forward by using the method of fidelity adjustment to achieve the dynamic configuration of virtual network.fidelity adjustment uses two technologies: based on experience model and intelligent decision.Based on experience model is simple and effective in the early stage.Another is used Case-Based Reasoning and Rule-Based Reasoning for intelligent decision.This method results in a more reasonable adjustment scheme,suitable for the latter which has accumulated a large amount of experimental data.In the last,designed the UI and database of virtual network construction,and described the usage and some problems should be noticed in length.
