Description

虚拟网络功能VNF的管理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种虚拟网络功能(Virtualized Network Function，简称为VNF)的管理方法及装置。
背景技术
在现有网络架构之中，网络功能与网络设备是超强耦合的关系，网络功能均通过专门设计的、厂商专有的设备来实现。这带来了诸多不便：比如这些设备在性能上的提高，受限于满足特定/定制化需求而且同时保持电信级可靠性的硬件的发展；又如，当运营商要部署新的业务时，须事先部署新设计的、具有相关专用功能的设备，这会提高运营商的业务部署成本。另一方面，随着中央处理器(Central Processing Unit，简称为CPU)及内存的性能快速地提高，通用型服务器上以软件形式运行网络功能就具备了基础条件，网络功能虚拟化(Network Function Virtualization，简称为NFV)技术也应运而生，它目标就是在通用的硬件设备上运行网络功能，从而通过大范围的部署，可降低资本输出(Capital Expenditure，简称为CAPEX)。“虚拟化”使得网络功能可以按需地部署及更新，且极大地方便远程管理及维护，可降低运营成本(Operating Expense，简称为OPEX)。
网络功能虚拟化后现有网络功能将在VNF上实现，可看作是VNF的应用层。每个VNF可以根据具体的应用配置实现不同的网络功能。因为VNF通常包含多个VNF组件VNFC(VNF Component)，VNFC一般由虚拟机实现，且VNFC和虚拟机通常是一一对应的关系，所以每个VNF将由多个虚拟机构成，每个虚拟机实现的功能以及能使用的虚拟资源都可能不同，同时由于VNF在其生命周期中可以进行扩展和收缩的操作，VNF包含的虚拟机数量以及虚拟机能使用的虚拟资源都可能在网络运行的过程中变化，在这种情况下为了使运营商能够了解虚拟网络功能的构成以及对应的各虚拟机的虚拟资源情况，网络管理系统(Network Management System，简称为NMS，又可称为NM)需要获取到相关的信息。而在传统网络管理系统中NMS通过网元管理系统(Element Management System，简称为EMS，又可称为EM)所管理的网元都是物理机，不存在虚拟机和虚拟资源，运营商通过NMS和EMS之间的北向接口也就不能获取到这些信息。
针对相关技术中，EM尚不能管理虚拟机和虚拟资源而导致的不能知晓当前虚拟机以及虚拟资源的运行情况的问题，尚未提出有效的解决方案。

为了使本技术领域的人员更好地理解本发明方案，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，所描述的实施例仅仅是本发明一部分的实施例，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他实施例，都应当属于本发明保护的范围。
为了解决上述技术问题，在本实施例中提供了一种VNF的管理方法，图1为根据本发明实施例的VNF的管理方法的流程图，如图1所示，包括以下步骤：
步骤S102，网元管理EM从VNF实体获取该VNF实体下虚拟机的相关信息；
步骤S104，上述EM根据上述相关信息为每一个上述虚拟机建立与该虚拟机对应的虚拟机对象实例；
步骤S106，上述EM对上述虚拟机对象实例进行管理。
通过上述各个步骤，采用根据虚拟机的相关信息建立与虚拟机对应的虚拟机对象实例，并通过对虚拟机对象实例(本发明实施例中提及的虚拟机对象示例均可以理解为是表示虚拟机的对象实例)进行管理来实现对虚拟机进行管理的技术方案，解决了相关技术中，EM尚不能管理虚拟机和虚拟资源而导致的不能知晓当前虚拟机以及虚拟资源的运行情况的问题，进而实现运营商能够获取到当前虚拟机的虚拟资源情况，扩展了虚拟网络功能的应用范围。
需要说明的是，在本发明实施例中，上述虚拟机的相关信息包括以下至少之一：虚拟机标识、虚拟机中的中央处理器CPU数量、虚拟机的内存容量、虚拟机的存储容量、虚拟机的位置、VNFC信息。
在具体实施过程中，由于VNF实体下的虚拟机已经建立了与虚拟机一一对应的虚拟机对象实例，那么VNF也是需要建立与其对应的管理功能对象实例的，并且，管理功能对象实例命名包含：一个或多个虚拟机对象实例，其中，上述管理功能对象实例中包括用于表示上述VNF实体的标识，如图2所示，表示虚拟网络功能的管理对象包含表示虚拟机的管理对象，表示虚拟机的管理对象的属性包括该虚拟机的标识，CPU数量，内存容量，存储容量，该虚拟机的位置，表示虚拟网络功能的管理对象属性中包含虚拟网络功能的标识。
进一步地，EM接收来自网络管理NM实体和/或运营支撑系统OSS的请求消息，其中，上述请求消息用于向上述EM请求上述VNF下上述虚拟机的相关信息；上述EM将上述VNF对应的管理功能对象实例以及上述管理功能对象实例包括的虚拟机对象实例发送至上述NM和/或OSS，以下结合一示例对上述技术方案进行说明：
如图3所示，图3为根据本发明实施例的管理VNF的虚拟机信息的流程图，包括以下步骤：
步骤S300，EM从VNF获取虚拟机相关信息；
步骤S302，VNF返回虚拟机相关信息；
步骤S304，建立、更新或删除虚拟机对应的管理对象实例，即EM根据获取的信息为每个虚拟机建立对应的管理对象实例，当然在需要的情况下，还可以更新虚拟机的管理对象实例属性、删除不存在的虚拟机对应的管理对象实例、增加虚拟机对应的表示虚拟机的对象实例，例如，可以通过以下技术方案实现：
EM接收来自VNF的第一变更通知信息；在上述第一变更信息的触发下，上述EM获取当前该VNF实体下虚拟机的上述相关信息；上述EM比较当前获取的上述相关信息与上述EM本地保存的上述相关信息；上述EM根据比较结果判定上述VNF增加或减少虚拟机。
其中，EM根据比较结果判定上述VNF增加或减少虚拟机可以通过以下技术方案实现：在上述比较结果指示上述当前获取的上述相关信息多于上述EM本地保存的上述相关信息时，上述EM判定上述VNF增加虚拟机；在上述比较结果指示上述当前获取的上述相关信息小于上述EM本地保存的上述相关信息时，上述EM判定上述VNF减少虚拟机。
并且，在EM根据比较结果判定上述VNF增加或减少虚拟机之后，还包括：在根据上述比较结果判定上述EM增加虚拟机时，上述EM为增加的虚拟机建立与该增加的虚拟机对应的虚拟机对象实例；在根据上述比较结果判定上述EM删除虚拟机时，上述EM删除与删除的虚拟机对应的虚拟机对象实例。

建立模块42，与获取模块40连接，设置为上述相关信息为每一个上述虚拟机建立与该虚拟机对应的虚拟机对象实例；
管理模块44，与建立模块42连接，设置为对上述虚拟机对象实例进行管理。
通过上述各个模块的综合作用，采用根据虚拟机的相关信息建立与虚拟机对应的虚拟机对象实例，并通过对虚拟机对象实例进行管理来实现对虚拟机进行管理的技术方案，解决了相关技术中，EM尚不能管理虚拟机和虚拟资源而导致的不能知晓当前虚拟机以及虚拟资源的运行情况的问题，进而实现运营商能够获取到当前虚拟机的虚拟资源情况，扩展了虚拟网络功能的应用范围。
可选地，获取模块40获取的上述虚拟机的相关信息包括以下至少之一：虚拟机标识、虚拟机中的中央处理器CPU数量、虚拟机的内存容量、虚拟机的存储容量、虚拟机的位置、VNFC信息。

步骤S604，NM实体接收上述EM实体根据上述请求消息返回的上述VNF对应的管理功能对象实例以及上述管理功能对象实例包含的虚拟机对象实例。
通过上述各个步骤，NM能够在向EM发送请求信息后，EM就能够根据虚拟机的相关信息建立与虚拟机对应的虚拟机对象实例，并根据上述请求消息返回的上述VNF对应的管理功能对象实例以及上述管理功能对象实例包含的虚拟机对象实例的技术方案，解决了相关技术中，EM尚不能管理虚拟机和虚拟资源而导致的不能知晓当前虚拟机以及虚拟资源的运行情况，进而NM就不能够根据EM获取到虚拟资源的运行情况的问题，进而实现运营商能够获取到当前虚拟机的虚拟资源情况，扩展了虚拟网络功能的应用范围。
在本发明实施例中，虚拟机的相关信息包括以下至少之一：虚拟机标识、虚拟机中的中央处理器CPU数量、虚拟机的内存容量、虚拟机的存储容量、虚拟机的位置、VNFC信息。

需要说明的是，发送模块70请求的虚拟机的相关信息包括：虚拟机标识、虚拟机中的中央处理器CPU数量、虚拟机的内存容量、虚拟机的存储容量、虚拟机的位置、VNFC信息。
