Description

管理指示发送、VNF自动伸缩功能的管理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种管理指示发送、VNF自动伸缩功能的管理方法及装置。
背景技术
在无线通讯系统的管理领域，网络管理系统(Network Management System，简称为NMS)与网元管理系统(Element Management System，简称为EMS)之间的接口称为北向接口(Itf-N)。EMS主要完成国际电信联盟(International Telecommunication Union，简称为ITU)电信管理网络(Telecommunications Management Network，简称为TMN)中的网元管理层(Element Management Layer，简称为EML)功能，即完成一个或多个移动通信设备的管理功能，通常不同设备供应商之间的EMS无法通用。NMS主要完成ITU TMN中的NML功能，负责一个被管网络内所有网元的管理。对于被管网络(称为子网)内存在多个设备供应商的情况，可以通过各自的EMS管理达到管理整个子网的目的。
目前，为了提高通讯网络的灵活性，降低管理成本，由运营商发起提出了网络功能虚拟化(Network Functions Virtualization，简称为NFV)概念，在使用NFV技术的情况下，原来的物理网元设备由虚拟化网络功能(Virtualized Network Function，简称为VNF)代替，使得网络功能与具体硬件解耦，如图1所示，其中，图1是相关技术中的网络功能虚拟化参考架构图，VNF与底层的网络功能虚拟化基础架构(Network Functions Virtualization Infrastructure，简称为NFVI)隔离。对于VNF的管理，通过EMS对VNF实例进行传统的维护管理功能，而VNF的生命周期管理功能则通过VNF管理器VNFM完成。底层的虚拟基础架构由虚拟基础架构管理器(Virtualised Infrastructure Manager，简称为VIM)进行管理。而具体的网络业务，则一般通过一个或多个VNF实例来完成。对网络业务的管理，则通过NFV编排器NFVO来进行。
实现网络功能虚拟化后，从应用层面来看，要建立一个网络业务实例时，需要先生成网络业务需要的VNF的实例，再由一个或多个VNF实例组成一个网络业务实例，通过网络业务实例来提供网络业务。而网络功能虚拟化后的一个好处是，随着网络的使用情况的变化，可以动态调整组成网络业务的VNF实例所使用的资源，即对VNF实例进行伸缩，以提供资源的利用率，并达到节能的目的。对于VNF实例伸缩的自动触发，目前有多种方案，可以由VNF实例本身的自动伸缩功能模块根据其自身的性能情况决定是否进行伸缩；也可以由VNFM上的VNF自动伸缩功能模块根据VNF实例及相关的资源的性能数据决定是否要对VNF实例进行伸缩；也可以由EMS上的VNF自动伸缩功能模块根据VNF的性能数据决定是否要对VNF实例进行伸缩；还可以在NMS层面，由位于NMS上的VNF自动伸缩功能模块根据VNF的性能数据决定是否要对VNF实例进行伸缩。这样，当不同层次的各个VNF自动 伸缩功能模块都在起作用的话，就可能出现VNF伸缩控制冲突的情况。
针对相关技术中存在的当不同层次的各个VNF自动伸缩功能模块都在起作用时，会造成VNF伸缩控制冲突的问题，目前尚未提出有效的解决方案。
