IP address distribution system and method facing distributed network simulation platform

Abstract

The invention relates to an IP address distribution system and method facing a distributed network simulation platform. The method includes: performing IP address range and IP block division; storing the kind circulation queue and free list of IP block use conditions; performing IP address distribution and IP address recycling. The method has the advantages customized IP addresses in examples can be processed, automatic IP address distribution is achieved, and flexibility of the network simulation platform is increased; a given range can be divided reasonably, and IP address resources can be utilized to the maximum extent; the IP addresses of examples can be isolated and executed, and network errors caused by IP address conflicts of different examples when physical network cards cannot be isolated are avoided; the IP address resources are stored in sequence by the kind circulation queue, the free list is used for storing discrete available IP address resources, sequential distribution and discrete distribution are combined, and the like.

Description

technical field [0001] The invention relates to a virtual network construction technology, in particular to an IP address allocation system and method for a distributed network simulation platform. Background technique [0002] Facing the research and testing requirements of cyberspace activities, the network simulation platform provides a real and credible basic platform for simulation and simulation, which is the main means of research on cyberspace activities at present. [0003] From the perspective of the physical platform architecture, the network simulation platform must adopt a distributed architecture in order to meet the needs of large-scale, multi-instance, and parallel network simulation, and the network simulation tasks are shared by multi-server clusters. From a technical point of view, the mainstream technical direction of building a virtual network is to integrate the advantages of simulation and simulation technologies to achieve an effective balance between...
