Cloud Simulation Scheduling Technology Research Based On The Communication Network Of Satellite Mobile

With the development of cloud computing technology, widely distributed computing resources can be constructed as a pool of shared resources, in which subscribers can conveniently obtain the resources when they need some resources. In order to avoid paralyzing of the simulation system, this thesis used VMWare migration technology that made sure simulation system transferred from one host to another in the real time, through data backup, load balancing and disaster recovery and maintenance, so that ensured reliability of the simulation.In order to realize the migration of virtual simulation system, the paper adopted the mechanism of VMware VMotion to realize the application not be interrupted in the process of whole migration to maintain the ESX host, that is to say, virtual machine could be transferred from one ESX server to another without affecting the business. This paper proposed a migration mechanism of resource scheduling in the virtual machines based on researching the improved Hungarian resource scheduling algorithm, making the virtual machines timely access to services.In the allocation of cloud simulation resource, to break through the limit problem of one-to-one assign based on the traditional Hungarian, improvement Hungary algorithm has been used to allocate the simulation resources efficiently. Though significantly simplified the infrastructure of IT (Information Technology), optimized and integrated to the resources, virtualization technology can obviously improve the efficiency and availability of resources and applications in the cloud simulation system. This paper combined VMware platform which has been constructed and deployed with the improved algorithm at last. Through improving the distributed simulation system of eleven-five, cloud application virtualization simulation system has been designed to realize the migration of simulation application system.
