Description

资产信息的管理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种资产信息的管理方法及装置。
背景技术
在现有网络架构之中，网络功能与网络设备具备超强的耦合关系，网络功能均可以通过专门设计的、厂商专有的设备来实现，由此带来了诸多不便。例如：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；又比如：当运营商需要部署新的业务时，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(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 Virtualisation，简称为NFV)技术也应运而生，其目标在于能够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，以降低资本性支出(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，由此可以降低运营成本(OPEX)。
图1是根据相关技术的网络功能虚拟化管理和编排(NFV Management and Orchestration，简称为NFV-MANO)的架构及参考点的示意图。如图1所示，虚拟网络功能编排器(Network Functions Virtualisation Orchestrator，简称为NFVO)负责网络服务的声明周期管理、跨虚拟化基础设施管理者(Virtualised Infrastructure Manager，简称为VIM)的网络功能虚拟化基础设施(Network Functions Virtualisation Infrastructure，简称为NFVI)资源调度等功能，虚拟网络功能管理者(VNF Manager，简称为VNFM)负责VNF实例的声明周期管理，每个VNF实例假设都存在一个与之关联的VNFM，VIM负责控制和管理NFVI计算、存储和网络资源。
在传统网络管理系统中，网络管理系统(Network Management System，简称为NMS)可以通过网元管理系统(Element Management System，简称为EMS)获取网元的资产信息。在网络功能虚拟化后，EMS只负责对VNF应用层的进行管理，软硬件资源则可以通过VIM进行管理，但是为了使运营商能够全面了解网络功能虚拟化后的资产情况，用于拓扑呈现，NMS或运营支撑系统(Operation Support System，简称为OSS)同样需要能够获取到资产信息。
综上所述，相关技术中在网络功能虚拟化后无法有效地获取网络基础设施的资产信息。
