A method and a system for quickly constructing a service scene network in a complex network simulation environment

Abstract

The invention discloses a method and a system for quickly constructing a service scene network under a complex network simulation environment. The method comprises the following steps: 1) generating aconfiguration file of the target scene network according to the network topology structure, the virtual router, the IP address segments and the VLAN required for the target scene network configuration, and sending the configuration file to the routing control network and the switch control network; 2) the switch control network completes the basic configuration of the node access network according to the configuration file; 3) the virtual routing server of the routing control network creates the virtual routing according to the configuration file, and divides the subnet and the VLAN accordingto the configuration file; 4) the physical interface of the virtual route server is connected with the core switch of the experimental network, and each node is connected; 5) the virtual routing server create a virtual connection between the virtual switches according to a configuration file; 6) the virtual routing server communicates with the virtual switches and establishes a management and control, and each virtual switch distributes a flow table.

Description

technical field [0001] The invention belongs to the technical field of Internet network security, and relates to a method and system for rapidly and large-scale realization of complex scene networks in a complex network simulation environment. Background technique [0002] The situation of confrontation in cyberspace is becoming increasingly severe, and cyber attack and defense have become the main content of cyber offensive and defensive confrontation in various countries. The network environment has developed from a simple Internet to a ubiquitous cyberspace, and the attack method has also developed from a single mode to a complex APT attack. The complex network simulation environment is an important infrastructure for network attack and defense drills and network new technology evaluation, and is used to improve the stability, security and performance of networks and information systems. All countries in the world attach great importance to the construction of a complex ...

Problems solved by technology

[0004] Aiming at the technical problems existing in the prior art, the purpose of the present invention is to provide a method and system for rapidly constructing complex network simulation environment scene networks, so as to solve the problems of real complex network simulation and flexible rapid construction. The present invention introduces SDN (Software Defined Networking) technology to generate a virtual router (vRouter), the SDN controller implements unified policy control on the virtual router through the OpenFlow protocol, realizes the creation of routing nodes in the scene network, and uses the virtual switch (OVS) technology to generate a virtual OVS Bridge (Bridge), to realize the division of network segments in the scene network

The present invention can create complex, multi-level, and multi-link network scenarios according to actual needs, solving the problem that traditional environments cannot simulate complex multi-level and multi-link network scenarios on a large scale, and because it is a virtual router, adding and deleting is flexible and free , not limited by physical devices, generating virtual devices is time-consuming and cost-effective, and solves the problem that the network structure cannot be flexibly changed
