【摘要】：隨著云計(jì)算技術(shù)的發(fā)展,大量分布在不同地方的計(jì)算機(jī)資源可以構(gòu)成一個(gè)共享資源池的形式,用戶(hù)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(dòng)通信網(wǎng)系統(tǒng)在研發(fā)時(shí)出現(xiàn)斷網(wǎng)、突然掉電等情況下,仿真系統(tǒng)將會(huì)出現(xiàn)癱瘓這樣的技術(shù)難題,本課題結(jié)合目前云計(jì)算虛擬化技術(shù)的發(fā)展,運(yùn)用VMWare遷移技術(shù),使得仿真應(yīng)用在不中斷的情況下實(shí)現(xiàn)實(shí)時(shí)遷移,對(duì)系統(tǒng)進(jìn)行數(shù)據(jù)備份、負(fù)載均衡、災(zāi)難恢復(fù)維護(hù),保證了仿真的可靠性。VMware VMotion可以對(duì)服務(wù)器、存儲(chǔ)以及網(wǎng)絡(luò)連接進(jìn)行完全的虛擬化,當(dāng)仿真應(yīng)用系統(tǒng)遇到突發(fā)情況時(shí),就可以將該應(yīng)用所在的虛擬機(jī)系統(tǒng)整體遷移到另外一臺(tái)物理主機(jī)上。本文采用VMware VMotion機(jī)制實(shí)現(xiàn)仿真系統(tǒng)的虛擬化遷移,實(shí)現(xiàn)了虛擬機(jī)不停機(jī)的情況下將一臺(tái)虛擬機(jī)從一個(gè)ESX服務(wù)器上遷移到另外一臺(tái)服務(wù)器上,這樣可以非常方便的在不影響業(yè)務(wù)的前提下對(duì)ESX主機(jī)進(jìn)行維護(hù)。本文通過(guò)研究改進(jìn)的匈牙利資源調(diào)度算法,提出了一種基于虛擬機(jī)負(fù)載遷移的資源調(diào)度機(jī)制,使虛擬機(jī)在發(fā)生遷移時(shí)及時(shí)獲得服務(wù)。云仿真資源在進(jìn)行虛擬化遷移時(shí)使用的改進(jìn)的匈牙利調(diào)度算法,突破了云仿真資源只適用于一對(duì)一指派問(wèn)題,為資源的一對(duì)多分配提出了新的思路,實(shí)現(xiàn)了云仿真資源的合理、有效分配。虛擬化技術(shù)能夠明顯提高云仿真系統(tǒng)中資源和應(yīng)用程序的效率和可用性,同時(shí)顯著簡(jiǎn)化了IT基礎(chǔ)設(shè)施,對(duì)資源進(jìn)行了優(yōu)化和整合。通過(guò)改進(jìn)“十一五”的分布式仿真系統(tǒng),設(shè)計(jì)了云仿真虛擬化應(yīng)用系統(tǒng),搭建VMware平臺(tái)后并對(duì)其進(jìn)行實(shí)施部署,結(jié)合改進(jìn)的資源調(diào)度算法,最終實(shí)現(xiàn)了仿真應(yīng)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.
