【摘要】：随着云计算技术的发展,大量分布在不同地方的计算机资源可以构成一个共享资源池的形式,用户可以从资源池中随意获取自已想要的资源。为了解决目前我军传统移动通信网系统在研发时出现断网、突然掉电等情况下,仿真系统将会出现瘫痪这样的技术难题,本课题结合目前云计算虚拟化技术的发展,运用VMWare迁移技术,使得仿真应用在不中断的情况下实现实时迁移,对系统进行数据备份、负载均衡、灾难恢复维护,保证了仿真的可靠性。VMware VMotion可以对服务器、存储以及网络连接进行完全的虚拟化,当仿真应用系统遇到突发情况时,就可以将该应用所在的虚拟机系统整体迁移到另外一台物理主机上。本文采用VMware VMotion机制实现仿真系统的虚拟化迁移,实现了虚拟机不停机的情况下将一台虚拟机从一个ESX服务器上迁移到另外一台服务器上,这样可以非常方便的在不影响业务的前提下对ESX主机进行维护。本文通过研究改进的匈牙利资源调度算法,提出了一种基于虚拟机负载迁移的资源调度机制,使虚拟机在发生迁移时及时获得服务。云仿真资源在进行虚拟化迁移时使用的改进的匈牙利调度算法,突破了云仿真资源只适用于一对一指派问题,为资源的一对多分配提出了新的思路,实现了云仿真资源的合理、有效分配。虚拟化技术能够明显提高云仿真系统中资源和应用程序的效率和可用性,同时显著简化了IT基础设施,对资源进行了优化和整合。通过改进“十一五”的分布式仿真系统,设计了云仿真虚拟化应用系统,搭建VMware平台后并对其进行实施部署,结合改进的资源调度算法,最终实现了仿真应用系统的迁移。
[Abstract]:With the development of cloud computing technology a large number of computer resources distributed in different places can form a pool of shared resources from which users can freely obtain their desired resources.In order to solve the technical problem that the traditional mobile communication network system of our army will be paralyzed in the development of the traditional mobile communication network system, such as disconnection of network and sudden power failure, this subject combines with the development of cloud computing virtualization technology.By using VMWare migration technology, the simulation application can realize real-time migration without interruption, data backup, load balance, disaster recovery and maintenance are carried out to ensure the reliability of simulation. VMware VMotion can be applied to the server.Storage and network connection are virtualized completely. When the simulation application system encounters a sudden situation, the virtual machine system in which the application is located can be migrated to another physical host as a whole.In this paper, VMware VMotion mechanism is used to realize the virtualization migration of the simulation system, and the virtual machine is migrated from one ESX server to another without downtime.This can be very convenient in the business without affecting the premise of the ESX mainframe maintenance.By studying the improved Hungarian resource scheduling algorithm, this paper proposes a resource scheduling mechanism based on the load migration of virtual machines, which enables virtual machines to get services in time when migration occurs.The improved Hungarian scheduling algorithm used in virtualization migration of cloud simulation resources breaks through the one-to-one assignment problem of cloud simulation resources, and puts forward a new idea for the one-to-many allocation of resources, and realizes the rationality of cloud simulation resources.Effective allocation.Virtualization technology can significantly improve the efficiency and availability of resources and applications in cloud simulation systems. It also simplifies the IT infrastructure and optimizes and integrates resources.By improving the "11th Five-Year Plan" distributed simulation system, the cloud simulation virtualization application system is designed, and the VMware platform is built and deployed. Finally, the migration of the simulation application system is realized by combining the improved resource scheduling algorithm.
