【摘要】：隨著云計算技術的發(fā)展,大量分布在不同地方的計算機資源可以構成一個共享資源池的形式,用戶可以從資源池中隨意獲取自已想要的資源。為了解決目前我軍傳統(tǒng)移動通信網系統(tǒng)在研發(fā)時出現斷網、突然掉電等情況下,仿真系統(tǒng)將會出現癱瘓這樣的技術難題,本課題結合目前云計算虛擬化技術的發(fā)展,運用VMWare遷移技術,使得仿真應用在不中斷的情況下實現實時遷移,對系統(tǒng)進行數據備份、負載均衡、災難恢復維護,保證了仿真的可靠性。VMware VMotion可以對服務器、存儲以及網絡連接進行完全的虛擬化,當仿真應用系統(tǒng)遇到突發(fā)情況時,就可以將該應用所在的虛擬機系統(tǒng)整體遷移到另外一臺物理主機上。本文采用VMware VMotion機制實現仿真系統(tǒng)的虛擬化遷移,實現了虛擬機不停機的情況下將一臺虛擬機從一個ESX服務器上遷移到另外一臺服務器上,這樣可以非常方便的在不影響業(yè)務的前提下對ESX主機進行維護。本文通過研究改進的匈牙利資源調度算法,提出了一種基于虛擬機負載遷移的資源調度機制,使虛擬機在發(fā)生遷移時及時獲得服務。云仿真資源在進行虛擬化遷移時使用的改進的匈牙利調度算法,突破了云仿真資源只適用于一對一指派問題,為資源的一對多分配提出了新的思路,實現了云仿真資源的合理、有效分配。虛擬化技術能夠明顯提高云仿真系統(tǒng)中資源和應用程序的效率和可用性,同時顯著簡化了IT基礎設施,對資源進行了優(yōu)化和整合。通過改進“十一五”的分布式仿真系統(tǒng),設計了云仿真虛擬化應用系統(tǒng),搭建VMware平臺后并對其進行實施部署,結合改進的資源調度算法,最終實現了仿真應用系統(tǒng)的遷移。
[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.
