Description

一种网络业务实例化的方法及设备 技术领域
本发明涉及通信技术领域，尤其涉及一种网络业务实例化的方法及设备。
背景技术
随着云技术的发展，虚拟化技术作为云计算的基础技术，在企业数据中心、大规模集群计算领域得到大规模使用。
网络功能虚拟化(英文：Network Functions Virtualization，简称：NFV)技术将一台计算机虚拟为多台虚拟逻辑计算机，即虚拟机(Virtual Machine，简称：VM)。虚拟机一般使用虚拟网卡、虚拟交换机以及连接机框内交换机或者架顶交换机的服务器物理网口，与服务器外部进行数据通信。
NFV技术通过借用信息技术(英文：Information Technology，简称：IT)的虚拟化技术，使得许多类型的网络设备可以合并到工业标准中，例如：服务、交换、存储等可以部署在数据中心或者网络节点中。将各种网络功能以软件方式实现，并能在工业标准的服务器上运行，并还能根据需要进行迁移、实例化、以及重新部署等等，并不需要安装新的设备，即产生虚拟网络功能(英文：Virtualized Network Function，简称：VNF)。多个虚拟网络功能之间可以实现网络业务(英文：Network Service，简称：NS)。
当网络业务发起者需要实现一个NS时，可以向资源管理实体发送NS初始化请求；其中，资源管理实体可以是网络功能虚拟化编制器(英文：NFV Orchestrator，简称：NFVO)。其中初始化请求中包括网络业务描述信息(英文：network service descriptor，简称：NSD)，NSD指明了该NS所需要的VNF。其中该NS需要的VNF中某个或者某几个VNF在网络架构中已经进行了实例化，已实例化的VNF可以服务于该NS，也可以服务于其他NS。
但是若NSD中指明的所需要的VNF是已经实例化的VNF，并且该VNF已经服务于其他NS，从而导致该VNF剩余的资源无法满足本次NS的需求。现有 技术中并没有一种方法可以使得VNF实例的资源在能够满足其他NS的同时，还能够满足本次NS的需求。

为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅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做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明实施例提供了一种网络业务实例化的方法及设备，用以解决现有技术中存在的无法实现VNF实例在能够服务其他NS的同时，还能够满足本次NS的需求的问题。其中，方法和设备是基于同一发明构思的，由于方法及设备解决问题的原理相似，因此设备与方法的实施可以相互参见，重复之处不再赘述。
参阅图1所示，本发明实施例提供了一种NFV系统的系统架构示意图，能够实现网络业务的实例化。网络业务指运行在网络中的应用，比如web服务，视频服务等。
其中，该NFV系统可以通过多种网络实现，例如数据中心网络、服务提供者网络、或者局域网(英文：Local Area Network，简称LAN)。
如图1所示，该NFV系统可以包括NFV管理和编制系统(英文：NFV Management and Orchestration System，简称NFV-MANO)101，NFV基础设施(NFV Infrastructure，简称：NFVI)102，多个虚拟网络功能(英文：Virtualized Network Function，简称：VNF)103，多个网元管理系统(英文element  management system，EMS)104，服务、VNF和基础设施描述(英文：Service VNF and Infrastructure Description)系统105，以及一个或多个运营支撑系统/业务支撑系统(英文：Operation Support System/Business Support System，简称：OSS/BSS)106。
NFV-MANO 101可以包括网络功能虚拟化编制器(英文：NFV Orchestrator，简称：NFVO)107、一个或多个VNFM 108，以及一个或多个虚拟化基础设施管理器(英文：Virtualized Infrastructure Manager，简称：VIM)109；NFVI 102可以包括计算硬件110、存储硬件111、网络硬件112组成的硬件资源层、虚拟化层、以及虚拟计算113(例如虚拟机)、虚拟存储114和虚拟网络115组成的虚拟资源层。
硬件资源层中的计算硬件110可以为专用的处理器或通用的用于提供处理和计算功能的处理器；存储硬件111用于提供存储能力，该存储能力可以是存储硬件111本身提供的(例如一台服务器的本地内存)，也可以通过网络提供(例如服务器通过网络连接一个网络存储设备)；网络硬件112可以是交换机、路由器和/或其他网络设备，网络硬件112用于实现多个设备之间的通信，多个设备之间通过无线或有线连接。
NFVI 102中的虚拟化层用于抽象硬件资源层的硬件资源，将VNF 103和硬件资源所属的物理层解耦，向VNF 103提供虚拟资源。
虚拟资源层可以包括虚拟计算113、虚拟存储114和虚拟网络115。虚拟计算113、虚拟存储114可以以虚拟机或其他虚拟容器的形式向VNF 103提供，例如一个或多个VNF 103可以部署在一台虚拟机上。虚拟化层通过抽象网络硬件112形成虚拟网络115。虚拟网络115，例如虚拟交换机(例如Vswitches)，用于实现多个虚拟机之间，或多个承载VNF的其他类型的虚拟容器之间的通信。网络硬件的虚拟化可以通过虚拟LAN(英文：Vritual LAN，简称：VLAN)、虚拟专用局域网业务(英文：Virtual Private LAN Service，简称：VPLS)、虚拟可扩展局域网(英文：Virtual eXtensible Local Area Network，简称：VxLAN)或通用路由封装网络虚拟化(英文：Nerwork Virtualization using  Generic Routing Encapsulation，简称：NVGRE)等技术实现。

NFV-MANO 101可以用于实现VNF 103和NFVI 102的监控和管理。NFVO 107可以与一个或多个VNFM 108进行通信以实现与资源相关的请求、发送配置信息给VNFM 108、以及收集VNF 103的状态信息。另外，NFVO 107还可以与VIM 109进行通信以实现资源分配，和/或，实现虚拟化硬件资源的配置信息和状态信息的预留和交换。VNFM 108可以用于管理一个或多个VNF103，执行各种管理功能，例如负责VNF103的初始化、更新、查询、和/或终止等。VIM 109可以用于控制和管理VNF 103和计算硬件110、存储硬件111、网络硬件112、虚拟计算113、虚拟存储114、虚拟网络115的交互。例如，VIM 109可以用于执行资源向VNF 103的分配操作。VNFM 108和VIM 109可以互相通信以交换虚拟化硬件资源配置和状态信息。
NFVI 102包含硬件和软件，二者共同建立虚拟化环境以部署、管理和执行VNF 103。换句话说，硬件资源层和虚拟资源层用于向各个VNF 103提供虚拟资源，例如虚拟机和/或其他形式的虚拟容器。
如图1所示，VNFM 108可以与VNF 103和EMS 104通信以执行VNF 103生命周期管理和实现配置/状态信息的交换。VNF 103是至少一个网络功能的虚拟化，该网络功能之前是由物理网络设备提供的。在一种实现方式下，VNF 103可以是一个虚拟化的移动管理实体(英文：Mobility Management Entity，简称：MME)节点，用于提供典型的非虚拟化的MME设备提供的所有网络功能。在另一种实现方式下，VNF 103可以用于实现非虚拟化的MME设备上提供的全部组件中的部分组件的功能。一个虚拟机(或其他形式的虚拟容器)上可以部署有一个或多个VNF 103。EMS 104可以用于管理一个或多个VNF。
本发明实施例提供了一种网络业务实例化的方法，如图2所示，该方法 包括：
