Description

一种设备状态及资源信息监测方法、相关设备及系统
本申请要求于2016年4月19日提交中国专利局、申请号为201610243244.1、发明名称为“一种设备状态及资源信息监测方法、相关设备及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及计算机技术领域，尤其涉及一种设备状态及资源信息监测方法、相关设备及系统。
背景技术
传统的电信系统通过各种专用的硬件设备组成，不同的应用采用不同的硬件设备。随着网络规模的增长，系统越来越复杂，带来了诸多的挑战，包括新增业务的开发上线、系统的运维、资源利用率等。为了应对这些挑战及利用IT业界的虚拟化技术及云计算技术，在2012年10月22日召开的“SDN and OpenFlow World Congress”会议上，全球主要的13个电信运营商联合发布了NFV白皮书，并宣布在ETSI成立NFV ISG，制定NFV的需求及技术框架，推动NFV的发展。
网络功能虚拟化(Network Function Virtualization，NFV)技术可以简单地理解为将电信网络中使用的各个网元的功能从目前的专用硬件平台迁移至通用的商用货架产品(COTS,Commercial-off-the-shelf)服务器上。通过NFV技术将电信网络中使用的各个网元转变成为独立的应用，可以灵活部署在基于标准的服务器、存储以及交换机等其他设备构建的统一基础设施平台上，并通过虚拟化技术，对基础设施硬件设备资源池化及虚拟化，对上层应用提供虚拟资源，例如，将虚拟网络功能(Virtual Network Function,VNF)部署到虚拟机或容器中，实现应用与硬件之间的解耦，使得虚拟资源供给速度大大增加实现应用、硬件解耦，使得每一个应用能够快速增加虚拟资源以实现快速扩展系统容量的目的。然而，实践中发现，每个虚拟机或容器都有自己的设备状态及资源监测模块，若一个服务器上部署上千个虚拟机或容器，将会有上千个资源监测模块，导致资源开销过大。
发明内容
本发明实施例公开了一种设备状态及资源信息监测方法、相关设备及系统，能够去除重复监控，降低资源监控开销。
本发明实施例公开了一种设备状态及资源信息监测方法，该方法包括：网络功能虚拟化基础设施NFVI接收虚拟网络功能VNF发送的订阅消息；其中，该订阅消息用于获取NFVI监测的部署VNF创建的虚拟机或容器的设备状态及资源监测信息；虚拟机或容器的设备状态包括分配给虚拟机或容器的物理处理器、物理内存、网卡及磁盘的状态；虚拟机或容器的资源监测信息包括分配给虚拟机或容器的物理处理器、物理内存、网卡及磁盘的利用率；NFVI根据订阅消息通过网络功能虚拟化基础设施接口向VNF上报部署VNF创建的虚拟机或 容器的设备状态及资源监测信息。采用本发明实施例，能够针对部署VNF而创建的多个虚拟器或容器，统一利用NFVI来监测虚拟机或容器的设备状态及资源监测信息，避免每个虚拟机或容器都有自己的设备状态及资源监测机制引起的重复监控，从而，降低了网络功能虚拟化系统的资源监控开销。

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他实施例，都属于本发明保护的范围。
为了更好的理解本发明实施例，下面先对本发明实施例的网络功能虚拟化NFV(Network Function Virtualization，网络功能虚拟化，简称NFV)的系统架构图进行描述。如图1所示，图1是NFV系统的架构图，NFV系统100可以在各种不同的网络环境中使用，例如：一个数据中心网络、运营商网络或局域网来实现。NFV系统100包括一个网络功能虚拟化管理和编排系统(NFV-Management and Orchestration，NFV-MANO)101、网络功能虚拟化基础设施(NFV Infrastructure，NFVI)130、多个网元管理(Element Management，EM)122、多个虚拟网络功能(Virtual Network Function，VNF)108、网络服务、VNF和基础设施描述126(Network Service，VNF and Infrastructure Description)以及运营支撑系统/业务支撑系统(Operation-Support System/Business Support System,OSS/BSS)124。其中，网络功能虚拟化编排和管理系统101包括网络功能虚拟化编排器(NFV Orchestrator，NFVO)102、一个或多个虚拟网络功能管理器(VNF Manager，VNFM)104和虚拟化基础设施管理器(Virtualized Infrastructure Manager，VIM)106。网络功能虚拟化基础设施130包括硬件资源层、虚拟化层和虚拟资源层，硬件资源层包括计算硬件112、存储硬件114和网络硬件116，虚拟资源层包括虚拟计算110、虚拟存储118和虚拟网络120。网络服务、VNF和基础设施描述126和运营支撑系统/业务支撑系统124在ETSI GS NFV 002 V1.1.1标准中有进一步的讨论。
NFV管理和编排系统101用于执行对虚拟网络功能108和网络功能虚拟化基础设施130的监视和管理。网络功能虚拟化编排器102可以实现在网络功能虚拟化基础设施130上的网络 服务(如L2和L3VPN服务)，也可以执行来自一个或多个虚拟网络功能管理器104的资源相关请求，发送配置信息到虚拟网络功能管理器104，并收集虚拟网络功能108的状态信息。另外，网络功能虚拟化编排器102可以与虚拟基础设施管理器106通信，以实现资源的分配和/或预留以及交换虚拟化硬件资源的配置和状态信息。虚拟网络功能管理器104可以管理一个或多个虚拟网络功能108。虚拟网络功能管理器104可以执行各种管理功能，例如实例化、更新、查询、缩放和/或终止虚拟网络功能108等。虚拟基础设施管理器106可以执行资源管理的功能，例如管理基础设施资源的分配(例如增加资源到容器)和操作功能(如收集网络功能虚拟化基础设施故障信息)。虚拟网络功能管理器104和虚拟基础设施管理器106可以相互通信进行资源分配和交换虚拟化硬件资源的配置和状态信息。
网络功能虚拟化基础设施130包括硬件资源、软件资源或两者的组合来完成虚拟化环境的部署。换句话说，硬件资源和虚拟化层用于提供虚拟化的资源，例如作为虚拟机和其他形式的容器，用于安装虚拟网络功能108。硬件资源包括计算硬件112、存储硬件114和网络硬件116。计算硬件112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。存储硬件114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)。在一种可能的实现方式中，计算硬件112和存储硬件114可以被集中在一起。网络硬件116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。
网络功能虚拟化基础设施130的虚拟化层可以从物理层抽象硬件资源和解耦虚拟网络功能108，以便向虚拟网络功能108提供虚拟化资源。虚拟资源层包括虚拟计算110、虚拟存储118和虚拟网络120。虚拟计算110和虚拟存储118可以以虚拟机和/或其他容器的形式提供给虚拟网络功能108。例如：一个或一个以上的虚拟网络功能108可以部署在一个虚拟机(Virtual Machine)上。虚拟化层抽象网络硬件116形成虚拟网络120，虚拟网络120可以包括虚拟交换机(Virtual Switch)，虚拟交换机用来提供虚拟机之间的连接。此外，网络硬件116中的传输网络，可以采用集中式控制平面和一个单独的转发平面(如软件定义网络，SDN)虚拟化。
如图1所示，虚拟网络功能管理器104可与虚拟网络功能108和网元管理122交互来对虚拟网络功能108的生命周期进行管理以及交换配置和状态信息。虚拟网络功能108可以被配置为通过一个物理网络设备执行的至少一个网络功能的虚拟化。例如，在一个实现方案中，虚拟网络功能108可以经过配置以提供IMS(IP Multimedia Subsystem，IP多媒体子系统，简称IMS)网络中的不同网元具备的功能，如P-CSCF(Proxy-Call Session Control Funtion，代理呼叫会话控制功能，简称P-CSCF)、S-CSCF(Serving-Call Session Control Funtion，服务呼叫会话控制功能，简称PSCSCF))或HSS(Home Subscriber Server，归属签约用户服务器，简称HSS)的网络功能等。网元管理122经过配置以对一个或一个以上的虚拟网络功能108进行管理。
在现有的NFV系统中，虚拟网络功能108可以部署在容器或虚拟机中，为实现对虚拟机或容器的设备状态和资源信息的监控，每个虚拟机或容器都有自己独立的设备状态和资源监测模块，若一个服务器上部署上千个虚拟机或容器，将会有上千个设备状态和资源监测模块，导致资源开销过大，造成资源浪费。
