【摘要】：网络管理的理念随着信息技术的发展在发生着深刻的变化。其中,由于面向服务体系结构具有松耦合性、良好的互操作性、服务和数据的可重用性、服务组合的易操作性、以及很大程度共享服务的能力,可以针对需要,使用网络对松耦合的组件进行部署和组合,重点解决原型系统开发过程中所需的网络仿真环境问题,因而成为当前研究的热点和难点。同时,虚拟化技术的发展对网管系统技术发展也带来了巨大的推动力。通过基础设施虚拟化,尤其是服务器虚拟化技术以及存储虚拟化技术,不仅实现了网管系统的瘦身,而且大大提高了容灾备份能力。同时,面向服务体系结构和虚拟化之间有一种高度协作的关系,随着网络规模的增大、管理服务的增多,支持这些服务的虚拟化技术的重要性就与日俱增。面向服务体系结构与虚拟化的融合有助于构建高度灵活的网管集成框架,实现管理资源的最优配置。本文介绍了基于虚拟化技术的管理服务部署和优化所用到的相关技术,主要包括虚拟化技术、Web Service技术、web集群及负载均衡等。同时,实现了对虚拟机资源进行有效数据获取而完成的虚拟机及其服务的管理服务,即虚拟机管理服务,从虚拟机管理服务的WSDL接口定义、基于axis的虚拟机管理服务、基于JSP技术的服务页面介绍了使用的相关技术,并对虚拟机管理服务实现的功能进行了阐释。同时,针对虚拟化平台上因服务访问量的不同导致个别节点负载过大、以及负载不均衡现象,设计并实现了虚拟化平台上服务的动态负载均衡模型,该模型主要使用集中式负载均衡算法,对需要集中的服务采用服务组的集群管理方法,在服务组内使用轮询机制对服务访问进行负载的分配,并根据实验环境的需要设计了整个负载均衡的系统模块构成以及算法流程。本文中的负载均衡模型经过实验验证,实现了在个别虚拟机过载时,通过上报计算中心,由计算中心根据流程算法决定服务迁移的目的节点,进行服务的迁移和负载的进一步分配,达到了负载均衡的效果。基于该负载均衡模型,本文在一定程度上实现了基于虚拟化技术的管理服务部署及优化方法。
[Abstract]:The concept of network management is undergoing profound changes with the development of information technology. Among them, due to the loose coupling of service-oriented architecture, good interoperability, reusability of services and data, ease of operation of service composition. And the ability to share services to a large extent, we can use the network to deploy and compose loosely coupled components to solve the network simulation environment problem in the development of prototype system. At the same time, the development of virtualization technology has brought a huge impetus to the development of network management system technology. Through infrastructure virtualization, especially server virtualization technology and storage virtualization technology, At the same time, there is a highly cooperative relationship between service-oriented architecture and virtualization. With the increase of network size, management services increase. The integration of service-oriented architecture and virtualization can help to build a highly flexible network management integration framework and achieve the optimal configuration of management resources. This paper introduces the related technologies used in the deployment and optimization of management services based on virtualization technology, including virtualization technology, web Service technology, web cluster, load balancing and so on. The management service of virtual machine and its service, which is defined from the WSDL interface of virtual machine management service, and the virtual machine management service based on axis, is realized. The service page based on JSP technology introduces the related technologies and explains the function of virtual machine management service. At the same time, the dynamic load balancing model of service on virtualization platform is designed and implemented in view of the excessive load of individual nodes and the unbalanced load caused by the different access to the service on the virtualization platform, and the dynamic load balancing model of the service on the virtualization platform is designed and implemented. In this model, the centralized load balancing algorithm is used, the service group cluster management method is adopted for the services that need to be centralized, and the polling mechanism is used in the service group to distribute the load of the service access. According to the needs of the experimental environment, the system modules and the algorithm flow of the load balancing are designed. The load balancing model in this paper is verified by experiments, and the load balancing model can be reported to the computing center when the individual virtual machines are overloaded. According to the flow algorithm, the computing center determines the destination node of service migration, carries out service migration and load distribution, and achieves the effect of load balancing. To some extent, this paper realizes the management service deployment and optimization method based on virtualization technology.
