具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为更好的理解本发明技术方案，下面先对网络功能虚拟化(Network Function Virtualization，NFV)混合组网系统的系统架构进行简要描述。
请参阅图1，图1是本发明实施例提供的一种网络功能虚拟化NFV混合组网系统100的系统架构图。其中，所述NFV混合组网系统100包括一个NFV MANO(NFV Management and Orchestration,网络功能虚拟化管理和编排系统)101、NFVI(NFV Infrastructure,网络功能虚拟化基础设施层)130、多个VNF(Virtual Network Function,虚拟网络功能)108、多个PNF(Physical Network Function，物理网络功能)109、多个EM(Element Management,网元管理)122(又称为虚拟网元管理模块)、多个EMS(Element management System， 网元管理系统)(又称为物理网元管理模块)123、NSD(Network Service Description，网络服务描述器)126、网络服务目录NS catalog和虚拟网络功能目录VNF catalog 127，以及OSS/BSS(Operation-Support System/Business Support System,业务支持管理系统)124。
其中，所述NFV MANO101包括NFVO(NFV Orchestrator,NFV编排器)102、一个或多个VNFM(VNF Manager,VNF管理器)104和VIM(Virtualized Infrastructure Manager,虚拟化基础设施管理器)106。其中，NFVO用于根据OSS/BSS发起的服务请求，编排管理资源，实现NFV服务，以及实时监测VNF、NFVI资源及运行状态信息；VNFM用于管理VNF生成周期，如启动、生存时间、VNF运行状态信息，且一个VNFM用于管理一个VNF；VIM用于管理、分配NFVI的资源，以及监测收集NFVI运行状态信息；
EM用于管理VNF，其中包括VNF的性能监控、业务配置等；EMS用于管理PNF，其中包括PNF的性能监控、业务配置等。
所述NFVI 130包括硬件资源层、虚拟化层(Virtualization Layer)131、虚拟资源层。所述硬件资源层包括计算硬件112、存储硬件114、网络硬件116，所述虚拟资源层包括虚拟计算110、虚拟存储118、虚拟网络120。
OSS/BSS124用于发起服务请求、分配服务所需的资源，以及故障处理。NS catalog用于存储所有上载的NS，支持NSD、VLD等部署模板的创建和管理，VNF catalog用于存储所有上载的VNF packages，支持VNFD、软件镜像、其他清单的创建和管理。
所述NFVI 130包括硬件资源、软件资源或两者的组合，用于完成虚拟化环境的部署。所述硬件资源和所述虚拟化层131用于提供虚拟化的资源，例如作为虚拟机和其它形式的虚拟容器，用于VNF108。
所述硬件资源包括计算硬件112、存储硬件114和网络硬件116。所述计算硬件112例如可以是市场上现成的硬件和/或用户定制的硬件，用来提供处理和计算资源。所述存储硬件114例如可以是网络内提供的存储容量或驻留在存储硬件114本身的存储容量(位于服务器内的本地存储器)。在一个实现方案中，计算硬件112和存储硬件114的资源可以被集中在一起。所述网络硬件 116例如可以是交换机、路由器和/或配置成具有交换功能的任何其他网络设备。网络硬件116可以横跨多个域，并且可以包括多个由一个或一个以上传输网络互连的网络。
所述虚拟化层131包括多种虚拟化技术，具体包括有虚拟机虚拟化技术和容器虚拟化技术，所述虚拟机虚拟化技术和所述容器虚拟化技术可以抽象资源和解耦所述VNF 108，以便向所述VNF 108提供虚拟化资源。所述虚拟计算110和所述虚拟存储118可以以虚拟机、或其他虚拟容器的形式提供给所述VNF 108。例如，一个或一个以上的VNF 108可以部署在一个虚拟机(Virtual Machine)上，也可以部署在容器(Container)中。
NFV混合组网系统的维护流程如下：(1)NFV MANO101会根据NSD中的虚拟网络功能描述器VNFD和物理网络功能描述器PNFD，分别进行VNF108和PNF109的实例化。(2)实例化网络连接，将VNF108、PNF109及其管理模块EM122、EMS123组成一个网络服务NS。(3)当VNF108性能发生异常时，EM122触发VNF scaling，或VNF migration，甚至故障恢复操作，进行异常恢复。(4)当PNF109发生异常的时候，EMS123会检测到PNF109性能异常，则进行相应的处理或者上报到OSS/BSS124，请求恢复PNF109的异常，其中还包括PNF109的其他生命周期操作及维护。在同一个NS网络中的PNF109和VNF108的相关操作(生命周期操作，如开启、关闭、扩容、告警处理等)，分别由EMS123来负责管理PNF109相关操作，由NFV MANO101来负责管理VNF108的相关操作。
可见，现有NFV混合组网系统中，PNF只能由传统EMS来管理，而VNF只能由EM进行管理，二者的管理维护分别由两个管理模块来负责，维护效率不高；而且在混合组网系统中，如果PNF成为网络性能的瓶颈，混合组网系统无法像VNF一样，对PNF进行动态的资源伸缩调整，只能上报管理员，进行增加或减少物理板卡，这影响了混合组网系统应对复杂环境的灵活度，影响网络体验。
针对上述现有的NFV混合组网系统100，如图2所示，在现有NFV混合组网系统中增加网络功能代理模块(图2中Agent)，基于该网络功能代理模 块构建包括虚拟网络功能VNF和物理网络功能PNF的增强型虚拟网络功能(eVNF，enhanced Virtual Network Function)，具体的，图中的CP-x为不同模块之间的连接点，其中CP-a/b是eVNF对外呈现的接口，CP-1/2/3/4是PNF和VNF的内部接口，该网络功能代理模块具体可以是设置于与PNF关联的硬件资源层，也可以设置于与VNF关联的硬件资源层，还可以设置于独立的硬件资源层，本发明实施例不做唯一限定。
