Abstract

An embodiment of the present invention provides a method for constructing a virtual-real decoupling simulation network, including: S1, obtaining a user-defined configuration simulation network planning script, which includes the simulation network topology and the function information of each node therein; S2, According to the simulation network planning script, each node of the simulation network is distributed and deployed on multiple physical hosts connected through the physical network; S3, build a data plane device connecting all nodes on each physical host, and configure it in a software-defined manner Based on the Overlay tunnel technology, each data plane device constructs a logical topology by networking scattered nodes to form a simulated network that is decoupled from the physical network and allows data frames to be transmitted hop by hop. The construction process of the present invention is completely transparent to the physical network cluster, and without depending on and without changing the networking and configuration of the physical network cluster, an arbitrary simulation network topology structure decoupling between virtual and real can be constructed.

Description

technical field

[0001] The present invention relates to the field of cyberspace security science, specifically to the field of large-scale Internet network structure, function and behavior simulation technology, and more specifically to a method for constructing a virtual-real decoupling simulation network. Background technique

[0002] A realistic cyberspace simulation platform is a key scientific device for scientific research, measurement and analysis of cyberspace security. With the rapid development of cyberspace technology, the development of cyberspace security research tasks such as experimenting and verifying various new network technologies, attack defense methods, and evaluating and analyzing network security strategies and network security risks is inseparable from the support of the cyberspace simulation platform.

[0003] Existing cyberspace simulation platforms can basically be divided into three categories: the first category is model-based simulators, which ...

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] As mentioned in the background technology section, the existing cloud computing and virtualization-based network shooting range tools can better meet the needs of large-scale Internet simulation construction, but because its core technology does not completely decouple the physical network cluster, the simulated network The structure, content, and behavior of the system depend on the configuration of the physical network cluster. The existing Overlay tunneling technology cannot be directly used for the simulation construction of large-scale Internet. The reason is that the propo...
