Description

一种告警信息上报方法及装置 技术领域
本发明涉及网络功能虚拟化技术领域，尤其涉及一种告警信息上报方法及装置。
背景技术
虚拟化技术是一种资源管理技术，可以将计算机的各种硬件资源，如服务器、网络、内存及存储等，予以抽象、转换后呈现出来，打破硬件结构间的不可切割的障碍，使用户可以比原本的组态更好的方式来应用这些资源。这些资源的虚拟化功能不受现有资源的架设方式、地域或物理组态所限制。
目前，当硬件资源发生故障等告警事件时，各硬件资源的监测器会将告警信息发送给管理硬件资源的虚拟化基础设施管理器(Virtual Infrastructure Manager，VIM)，再由VIM将其转发给管理虚拟化功能的虚拟网络功能管理器(Virtual Network Function Manager，VNFM)，VNFM接收到该告警信息后根据自身能力进行相应的处理，并将处理后的告警信息上报给网元管理器(Element Manager，EM)，由EM综合其他的告警信息等进行最终的故障处理。
在上述告警信息上报过程中，该告警信息需要经过硬件资源和虚拟化功能等管理面的管理器VIM和VNFM，之后再上报到EM，上报的路径较长，而且上报过程中需要经过一定的处理，从而增加了告警信息上报的时延，导致EM不能及时获取底层的告警信息，做出相应的处理，影响故障的快速处理和恢复。

在介绍本发明之前，首先对网络功能虚拟化(Network Function Virtualization，NFV)技术、本发明实施例所应用的NFV系统架构进行简单介绍。
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，从而推动了NFV技术的发展。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，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，或者能够快速减少虚拟资源以实现收缩系统容量的目的，大大提升网络的弹性。
图1是NFV的系统架构图，该NFV系统可以在各种网络中使用，例如，在一个数据中心网络、运营商网络或局域网来实现。该NFV系统包括一个NFV管理和编排系统(NFV Management and Orchestration,NFV-MANO)101、NFV基础设施层(NFV Infrastructure,NFVI)130、虚拟网络功能(Virtual Network Function,VNF)108、网元管理(Element Management,EM)122、VNF描述器和基础设施描述器(VNF and Infrastructure Description)126，以及业务支持管理系统(Operation Support System/Business Support System,OSS/BSS)124。其中，NFV-MANO 101包括NFV编排器(NFV Orchestrator，NFVO)102，一个或多个VNFM(VNF Manager,VNFM)104和虚拟化基础设施管理器(Virtualized Infrastructure Manager,VIM)106。NFVI 130包括计算硬件112、存储硬件114、网络硬件116、虚拟化层(Virtualization Layer)、虚拟计算110、虚拟存储118和虚拟网络120。
NFV-MANO 101用于执行对VNF 108和NFVI 130的监视和管理。NFVO 102可以实现在NFVI 130上的网络服务，也可以执行来自一个或多个VNFM 104的资源相关请求，发送配置信息到VNFM 104，并收集VNF108的状态信息。另外，NFVO 102可以与VIM 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。所述VNFM 104可以管理一个或多个VNF 108。VNFM 104可以执行各种管理功能，如实例化、更新、查询、缩放和/或终止VNF 108等。VIM 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(例如增加资源到虚拟容器)和操作功能(如收集NFVI故障信息)。VNFM 104和VIM 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。

NFVI 130里面的虚拟化层可以从物理层抽象硬件资源和解耦VNF108，以便向VNF 108提供虚拟化资源。虚拟资源层包括虚拟计算110，虚拟存储器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/或其他虚拟容器的形式提供给VNF 108。例如，一个或一个以上的VNF 108可以部署在一个虚拟机(Virtual Machine，VM)上。虚拟化层抽象网络硬件116从而形成虚拟网络120，虚拟网络120可以包括虚拟交换机(Virtual Switch)，所述虚拟交换机用来提供虚拟机和其他虚拟机之间的连接。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，VNFM104可以与VNF 108和EM 122交互来对VNF的生命周期进行管理以及交换配置和状态信息。VNF 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。

图3为本发明实施例提供的一种告警信息上报方法的流程示意图，该方法应用于图2所示的NFVI，参见图3，该方法包括以下几个步骤。
步骤201：监控器检测硬件层和/或软件层的物理资源告警信息，并将该物理资源告警信息发送给告警分类器。
其中，硬件层的监控器可以对硬件层的硬件资源进行检测，该硬件资源可以包括计算硬件、存储硬件和网络硬件等，比如该计算硬件可以为中央处理器(Central Processing Unit，CPU)，该存储硬件可以为存储器；软件层的监控器可以对软件资源进行检测，该软件资源可以包括NFVI的操作系统和虚拟机管理器等。
具体的，当硬件层的监控器检测到硬件资源发生告警时，可以将硬件资源相关的告警信息发送给告警分类器；和/或，当软件层的监控器检测到软件资源发生告警时，可以将软件资源相关的告警信息发送给告警分类器。其中，物理资源告警信息可以包括硬件资源相关的告警信息，和/或软件资源相关的告警信息。
步骤202：告警分类器根据该物理资源告警信息，从虚拟机管理器中获取对应的虚拟机信息。
其中，该物理资源告警信息可以包括告警标识和故障源标识，该告警标识用于标识告警的类型，该故障源标识用于标识发生告警的单元，比如 CPU、存储器、或者操作系统等等。
具体的，当告警分类器根据该物理资源告警信息，从虚拟机管理器中获取对应的虚拟机信息时，告警分类器可以向虚拟机管理器发送查询请求，该查询请求包括故障源标识；虚拟机管理器根据故障源标识，从第一对应信息中查询对应的虚拟机信息，并将该虚拟机信息发送给告警分类器；第一对应信息包括至少一个物理资源信息、以及与每个物理资源信息对应的虚拟机信息。
其中，第一对应信息包括的至少一个物理资源信息中的物理资源可以包括硬件资源和/或软件资源。在本发明实施例中，虚拟机管理器可以用于管理物理资源与虚拟机之间的对应关系，也即是，虚拟机管理器中存储有至少一个物理资源标识、以及与每个物理资源信息对应的虚拟机信息，该物理资源信息可以包括物理资源标识，该虚拟机信息可以包括虚拟机标识。
比如，该物理资源信息包括物理资源标识，该虚拟机信息包括虚拟机标识，当告警分类器向虚拟机管理器发送查询请求，该查询请求包括故障源标识为CPU标识，即NFVI的CPU发生告警时，虚拟机管理器可以从第一对应信息中查询与该发生告警的CPU对应的虚拟资源中的虚拟CPU，以及基于该虚拟CPU创建的虚拟机的标识，若对应的虚拟机标识为VM1，则虚拟机管理器将该虚拟机标识VM1发送给告警分类器。
需要说明的是，每个物理资源标识对应的虚拟机标识可以为一个，也可以为多个，比如，当NFVI的CPU发生告警，且基于虚拟资源中的虚拟CPU创建了多个虚拟机时，则虚拟机管理器查询得到的虚拟机标识也为多个，本发明实施例对此不作限定。
步骤203：告警分类器根据虚拟机信息，将物理资源告警信息发送给与虚拟机信息对应的模拟处理器。
由于NFVI中可以包括一个或多个模拟处理器，且一个模拟处理器可以对应一个虚拟机，因此，当告警分类器将该物理资源告警信息发送给对应的模拟处理器时，告警分类器可以根据虚拟机信息，将物理资源告警信息发送给与虚拟机信息对应的模拟处理器，也即是，告警分类器可以将该物理资源告警信息发送给与虚拟机标识对应的模拟处理器。
具体的，告警分类器可以通过与虚拟机标识对应的模拟处理器中的I/O设备将该物理资源告警信息发送给该模拟处理器。其中，告警分类器通过模拟处理器中的I/O设备发送该物理资源告警信息的过程可以参考相关技术，本发明实施例对此不作详细阐述。
步骤204：模拟处理器根据物理资源告警信息，获取对应的虚拟资源告警信息，并将物理资源告警信息和虚拟资源告警信息上报给与虚拟机信息对应的虚拟机中的VNF，以使VNF将其上报给对应的网元管理。
其中，当硬件资源和/或软件资源发生告警时，与该硬件资源和/或软件资源对应的虚拟资源也会发生告警，比如，当硬件资源CPU发生告警时，对应的虚拟资源虚拟CPU也发生告警，模拟处理器可以接收该虚拟资源对应的告警信息，这里称为虚拟资源告警信息。
具体的，当模拟处理器接收到该物理资源告警信息时，模拟处理器可以根据该物理资源告警信息，获取与该物理资源告警信息对应的虚拟资源告警信息，并将该物理资源告警信息和虚拟资源告警信息一起上报给与虚拟机标识对应的虚拟机中的VNF，由VNF将其发送给对应的网元管理，从而可以将NFVI底层硬件和/或软件的告警信息，以及相关联的虚拟资源告警信息，直接通过虚拟机上报到网元管器，缩短上报路径，使网元管理器更早获取底层的告警信息，并进行及时处理，从而尽可能避免NFVI上的业务受到影响。
进一步，该虚拟机信息还包括后端告警驱动标识，模拟处理器中设置有至少一个后端告警驱动，以及与每个后端告警驱动对应的虚拟机的前端告警驱动。
相应的，上述步骤203中告警分类器根据虚拟机信息，将物理资源告警信息发送给与虚拟机信息对应的模拟处理器的过程，具体可以为步骤203a。
步骤203a：告警分类器根据后端告警驱动标识，将物理资源告警信息发送给与后端告警标识对应的模拟处理器中的后端告警驱动。
具体的，当虚拟机管理器发送给告警分类器的虚拟机信息还包括后端告警驱动标识时，告警分类器可以根据该后端告警驱动标识，查找到对应的模拟处理器，并从该模拟处理器对应的至少一个后端告警驱动中，查到 到与该后端告警标识对应的后端告警驱动，之后，告警分类器将该物理资源告警信发送给该后端告警驱动。
相应的，步骤204中模拟处理器根据物理资源告警信息，获取对应的虚拟资源告警信息，并将物理资源告警信息和虚拟资源告警信息上报给与虚拟机信息对应的虚拟机中的VNF，以使VNF将其上报给对应的网元管理的过程，具体可以包括步骤204a-步骤204c。
步骤204a：后端告警驱动根据物理资源告警信息，从模拟处理器中获取对应的虚拟资源告警信息。
由于模拟处理器可以接收虚拟资源告警信息，因此，当后端告警驱动接收到该物理资源告警信息时，后端告警驱动可以根据该物理资源告警信息，从模拟处理器中获取对应的虚拟资源告警信息。
步骤204b：后端告警驱动将物理资源告警信息和虚拟资源告警信息发送给对应的虚拟机中的前端告警驱动。
当后端告警驱动获取对应的虚拟资源告警信息时，后端告警驱动可以根据预设的至少一个后端告警驱动中每个后端告警驱动与虚拟机的前端告警驱动之间的对应关系，查到对应的前端告警驱动，并将该物理资源告警信息和虚拟资源告警信息发送给对应的虚拟机中的前端告警驱动。
步骤204c：前端告警驱动将物理资源告警信息和虚拟资源告警信息上报给与虚拟机标识对应的虚拟机中的VNF，以使VNF将其上报给对应的网元管理。
当前端告警驱动接收到该物理资源告警信息和虚拟资源告警信息时，前端告警驱动可以将该物理资源告警信息和虚拟资源告警信息一起上报给与虚拟机标识对应的虚拟机中的VNF，由VNF将其发送给对应的网元管理。
上述步骤204a-204c中，通过在模拟处理器中增加后端告警驱动，在虚拟机中增加前端告警驱动，后端告警驱动与前端告警驱动一一对应，可以使相应的告警信息沿着预设的传输通道上报到网元管理，减少告警信息的上报时延。
需要说明的是，虚拟机可以包括一个或者多个VNF，且将物理资源告警信息和虚拟资源告警信息发送给与虚拟机标识对应的VNF时，是发 送给虚拟机包括的每个VNF，由每个VNF将其上报给各自对应的网元管理。上述图2是以虚拟机包括一个VNF为例进行介绍的，上述图2并不对本发明构成限定。
