Description

虚拟网络功能VNF的虚拟资源的管理方法及装置 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VNF的虚拟资源的管理方法及装置。
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，可降低资本支出(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)。
图1是相关技术中网络功能虚拟化NFV的结构框图，如图1所示，相关技术中网络功能将在虚拟网络功能(Virtualised Network Function,简称VNF)上的实现可看作是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。NFV引入后，相关技术中的网络的管理架构也发生了很大变化，图2是相关技术中NFV管理和编排器NFV-MANO的结构框图，如图2所示为NFV管理和编排器(NFV Management and Orchestration，简称NFV-MANO)的架构图及参考点，其中，网络功能虚拟化编排器(Network Functions Virtualisation Orchestrator，简称NFVO)负责网络服务的生命周期管理、跨虚拟架构管理者(Virtualised Infrastructure Manager，简称VIM)的网络功能虚拟化基础设施(Network Functions Virtualization Infrastructure，简称NFVI)资源调度等功能，VNF管理者(VNF Manager，简称VNFM)负责VNF实例的生命周期管理，每个VNF实例假设都有一个关联的VNFM，VIM负责控制和管理NFVI计算，存储和网络资源。
VNF的生命周期操作包括：实例化VNF(Instantiate VNF)、结束VNF实例(Terminate VNF)、伸缩VNF(Scaling VNF，可细分为Scale in、Scale out、Scale up、Scale down)等。VNF能使用的虚拟资源会根据VNF伸缩操作变化，虚拟资源主要包 括虚拟的计算、存储和网络资源，VNF的所有虚拟资源是分配给不同的虚拟机来进行使用的。VNF可能由多个VNF组件VNFC(VNF Component)构成，VNFC通常由一个虚拟机VM(Virtual Machine)实现，也可在一个虚拟机上实现多个VNFC，不排除一个VNFC由多个VM实现的情况，但不常用。
传统网管多采用包含网络管理(Network Management,简称为NM)或运营支撑系统(Operation Support System，简称为OSS)、网元管理(Element Management简称为EM)和网元设备的三层管理结构，其中，NM和EM之间的接口是北向接口，EM和网元之间是南向接口。管理系统在北向接口上将每类网元模型化为一个管理对象类，每个网元都有会有一个所属对象类的管理对象实例。管理对象实例中包含了网元的配置信息，该对象实例通过区别名(Distinguish Name，简称为DN)来表标识，管理系统通过对管理对象实例的创建、删除和更新操作来完成对网元的配置信息的管理。
在网络功能虚拟化后，传统管理实体NM和EM不仅不能对VNF的虚拟资源情况进行监控，更不能随着VNF的虚拟资源的动态变化进行动态管理，进而在性能测量中不能以虚拟机为测量对象来下发虚拟资源相关的性能测量任务，以虚拟机为测量对象可以方便运营商通过对比从VNF上报的虚拟资源使用情况和从NFVI的虚拟机监控器(Hypervisor)获取的虚拟资源使用情况来评估VNF运行中非业务层消耗的资源，同时在告警管理方面，因为EM和NM不能对VNF的虚拟资源进行管理，VNF的应用层告警和虚拟资源相关告警的告警信息中即使携带了产生告警的虚拟机的信息，NM也无法自动解析和识别，不便于运营商自动统计分析及进行VNF应用层告警和虚拟资源相关告警与NFVI产生的物理资源告警进行关联。
针对相关技术中管理NM和EM不能对VNF虚拟资源实现动态管理的问题，目前尚未提出有效的解决方案。
