Network Functions Virtualisation(NFV，网络功能虚拟化)是由电信网络运营商提出的，是借助IT虚拟化技术，采用业界标准的大容量服务器、存储器和交换机承载各种各样的网络软件功能的技术标准。NFV实现了软件的灵活加载，实现在数据中心、网络节点和用户端等各个位置灵活的部署配置，从而加快网络部署和调整的速度，降低业务部署的复杂度，提高网络设备的统一化、通用化、适配性等。
另外，网络功能虚拟化的实现必须能与运营商当前的老网络设备共存，并与已有的(Element Management System，网元管理系统)EMS、(Network Management System，网络管理系统)NMS、OSS(Operation support system，运营支撑系统)/BSS(Business support system，业务支撑系统)，以及已有的IT编排系统兼容。
此外，网络功能虚拟化通过运行在开放、标准的基础设施上的软件网络设备提供弹性、灵活的处理能力，并向接口管理和编排快速拉齐。这将大大降低把新虚拟装置集成到网络运营商运营环境中的时间、成本。因此，网络功能虚拟化只有当所有相关功能自动化后才具有伸缩性。
但是，随着虚拟化技术的发展，电信运营商和用户还希望网络功能虚拟化后网元管理系统能在提供现有FCAPS(Fault Management、Configuration Management、Accounting Management、Performance Management、Security Management，故障管理、配置管理、计费管理、性能管理、安全管理)功能基础上适配网元虚拟化的一些接口和特性变化， 网元管理系统也能够运行在虚拟化环境中。然而，在现有的ETSI(European Telecommunications Standards Institute，欧洲电信标准协会)NFV架构中，NFV没有考虑EMS的自动部署和管理。

其中，所述应用程序可优选为网元管理系统EMS。
下面结合虚拟机和虚拟化网络功能管理器VNFM双方对本发明提供的虚拟化环境下自动部署应用程序的方法进行说明，应用程序以网元管理系统EMS为例。
本发明提供的方案可以概述为：在运行EMS的虚拟机中启动一个代理进程，通过该进程实现与(Virtualized Network Function Manager虚拟化网络功能管理器)VNFM的交互，完成EMS在虚拟化环境中的自动部署。
VNFM接收到EMS自动部署请求后，向底层的IaaS(Infrastructure as a Service，即基础设施即服务)平台申请创建虚拟机，然后根据配置信息部署虚拟机并启动虚拟机，虚拟机首次启动时运行EMS代理进程，通过该代理进程完成EMS版本的下载、安装以及配置，从而实现EMS在虚拟 化平台的自动部署。
所述代理进程包括主控模块、Socket管理模块、下载管理模块、安装管理模块。
主控模块：负责与VNFM的交互，实现EMS代理进程总的流程控制；代理进程运行时，首先启动Socket管理模块，开启监听端口，将代理进程作为Socket服务端，接收来自VNFM的建链请求；其次，完成EMS版本文件下载；最后，完成EMS软件的安装以及修改EMS运行需要的一些参数。
Socket管理模块：实现代理进程与VNFM之间的Socket通讯链路管理，接收VNFM的建链请求和维护链路心跳。
下载管理模块：实现从VNFM指定的版本服务器下载EMS的版本包。
安装管理模块：实现网元管理软件静默安装流程控制，以及网元管理软件安装后运行参数的修改。
下面作进一步详细的描述，应用程序以网元管理系统EMS为例。
如图3所示，本发明是基于ETSI NFV架构实现，在ETSI NFV架构中，虚拟化网络功能管理器VNFM是属于虚拟化网络管理层，虚拟化网络功能VNF是作为一个纯软件实现的网络功能，从安装部署的角度来说，VNF就是一个虚拟机31(包括EMS代理进程32、EMS应用程序33和操作系统OS34)，EMS代理进程运行在虚拟机中，与VNFM进行交互。
VNFM接收自动部署请求后，响应该请求并完成虚拟资源申请，获取虚拟资源申请结果后，向底层的IaaS(基础设施即服务，Infrastructure as a Service)平台发起创建虚拟机请求，请求中会附带虚拟机的配置信息；底层的IaaS平台响应创建虚拟机请求，完成虚拟机创建并将请求中附带的虚拟机配置信息作为注入文件传递到虚拟机中。
虚拟机首次启动时，会运行一个EMS代理进程，在该代理进程启动后，读取上述的注入文件并缓存起来，然后在指定端口启动监听，监听来自VNFM的指令。
如图4所示，EMS代理进程41包括主控模块42、Socket管理模块43、下载管理模块44、安装管理模块45。
EMS代理进程41：完成EMS的自动部署；该代理进程仅在虚拟机首次启动时运行。
主控模块42：完成EMS代理进程与VNFM子系统之间的消息交互；作为代理进程总的控制模块，主控模块运行后，调用Socket管理模块43，监听VNFM的建链请求；与VNFM建链成功后，接收VNFM发送的下载请求，调用下载管理模块44，从版本服务器下载EMS的软件包；完成软件包下载后，调用安装管理模块45，完成EMS软件的安装、部署、启动，向VNFM发送EMS自动部署成功消息。
Socket管理模块43：完成与VNFM之间的Socket链路管理；主控模块42读取该模块的Socket端口消息，当接收到VNFM的建链请求后，主控模块42完成与VNFM子系统的建链；当接收到周期性的心跳检测请求时，主控模块42通过Socket端口响应该心跳请求；当接收到下载请求时，主控模块42调用下载模块44下载EMS软件包，下载未完成之前主控模块42会通过Socket端口定时发送下载进度消息；当接收到安装请求时，主控模块42调用安装管理模块45，开始安装EMS软件，安装过程中主控模块42会通过Socket端口定时发送安装进度消息；安装完成后，主控模块42通过Socket端口发送自动部署完成消息。
下载管理模块44：完成从VNFM指定的版本服务器获取EMS程序包；当主控模块42读取到下载请求消息时，主控模块42解析下载请求消息，获取消息中的版本服务器信息，调用本模块，从指定的版本服务器下载EMS软件包，下载过程计算下载进度，将进度信息发送给主控模块42。
安装管理模块45：完成网元管理软件静默安装的流程控制，以及网元管理软件安装后运行参数的修改；当主控模块42读取到安装部署请求消息时，主控模块42调用本模块，开始静默安装、部署EMS，安装过程中，定时向主控模块42反馈安装进度，直至安装完成。
也就是，在VNFM接收到EMS自动部署请求后，向底层IaaS平台发送创建虚拟机请求，请求中会附带虚拟机的配置信息；IaaS平台响应创建虚拟机的请求，完成虚拟机创建及启动，并将配置信息在虚拟机首次启动时注入到虚拟机中，之后，如图5所示，EMS自动部署流程涉及到四个部分，即VNFM子系统，虚拟机VM，EMS代理进程和EMS，步骤如下：
步骤51：虚拟机启动成功后，启动EMS代理进程(EMSAgent)，该代理进程程序置于虚拟机镜像中，限制只在虚拟机首次启动时运行该代理进程。
步骤52：EMSAgent进程启动后，在固定端口开启监听，将EMSAgent作为Socket服务器监听来自VNFM的建链请求。
步骤53：VNFM向EMSAgent进程发起建链请求。
步骤54：EMSAgent向VNFM返回建链成功消息，VNFM与EMSAgent之间建立Socket连接，该连接在自动部署完成之前会一直存在。
步骤55：在VNFM与EMSAgent之间建立Socket连接后，VNFM定时向EMSAgent发送心跳链路检测，以检测Socket链路状态。
步骤56：EMSAgent收到心跳链路检测消息后，返回响应消息。
步骤57：如果步骤55中检测到3个心跳周期没有响应，则VNFM重新向EMSAgent发起建链请求，超过指定时间没有完成建链，则VNFM返回自动部署失败。
步骤58：EMSAgent接收到VNFM重新发起建链请求，指定时间内完成建链，返回重新建链成功消息。
步骤59：VNFM检测到步骤54或58返回的建链成功消息后，向EMSAgent发送下载请求，请求中会附带版本服务器信息。
步骤510：EMSAgent接收到下载请求后，获取消息中的版本服务器信息，启动下载模块；通过下载模块从VNFM指定的版本服务器下载EMS软件包。
步骤511：EMSAgent在下载过程中，计算下载进度信息并上报给 VNFM。
步骤512：当VNFM接收到下载进度100％的消息后，向EMSAgent发送安装EMS软件包请求。
步骤513：EMSAgent接收到安装请求后，启动安装模块，开始安装EMS。
步骤514：EMSAgent在安装EMS的过程中，计算安装进程信息并上报给VNFM。
步骤515：EMSAgent完成EMS软件包安装后，根据虚拟机的配置信息修改EMS的运行参数，修改完成后启动EMS。
步骤516：EMSAgent检测到EMS所有进程均启动完毕后，向VNFM上报自动部署完成消息。
其中，EMSAgent可通过轮询EMS所有进程的启动进度来检测，也可以让EMS所有进程向EMSAgent上报启动进度来检测。
