背景技术Background technique

现今运营商使用的系统架构中，网络功能是由一些专用硬件来提供的。网元(Network Element，NE)是网络管理中监视和管理的最小单位，网元管理系统(Network Management system，EMS)就是用来管理特定类型的一个或多个网元的系统，这其中也包括了对网络设备的性能管理，整个运营系统的性能很大程度上取决于底层专用的网络设备。In the system architecture used by operators today, network functions are provided by some dedicated hardware.

Network Element Management System (EMS) is a system used to manage one or more network elements of a specific type, including In addition to the performance management of network equipment, the performance of the entire operating system largely depends on the underlying dedicated network equipment.

然而，随着网络功能虚拟化(Network Function Virtualization，NFV)的发展，运营商现有的管理系统会发生很大改变。由于部分网络功能以软件应用的形式实现，传统EMS及网络管理系统不足以良好的管理这些虚拟网络功能，且在网管系统和网络功能虚拟化的编排器同时工作时，不能避免两个系统同时触发执行同一个生命周期管理的调度消息，容易造成网元生命周期管理操作混乱。众所周知，运营商需要为广大用户提供高性能的业务。因此，在运营商引入VNF后如何处理两个系统之间的调度消息，迫切需要一个解决方案。However, with the development of Network Function Virtualization (Network Function Virtualization, NFV), the operator's existing management system will undergo great changes. Since some network functions are implemented in the form of software applications, traditional EMS and network management systems are not enough to manage these virtual network functions well, and when the network management system and the network function virtualization orchestrator work at the same time, it is unavoidable that the two systems will be triggered at the same time Executing the scheduling messages for the same life cycle management may easily cause confusion in network element life cycle management operations. As we all know, operators need to provide high-performance services for a large number of users. Therefore, there is an urgent need for a solution on how to handle scheduling messages between the two systems after the operator introduces the VNF.

下面分别说明本发明实施例中VNFM和EMS的性能管理过程。The performance management processes of the VNFM and the EMS in the embodiments of the present invention are described below respectively.

(1)VNFM对VNF性能管理数据和VR性能管理数据的管理过程(1) VNFM's management process of VNF performance management data and VR performance management data

如图3所示，本发明实施例包括：As shown in Figure 3, the embodiment of the present invention includes:

步骤31：VNFM从VNF中获取VNF性能管理数据；Step 31: VNFM obtains VNF performance management data from VNF;

步骤32：VIM向VNFM发送虚拟资源VR性能管理数据；Step 32: VIM sends virtual resource VR performance management data to VNFM;

在本发明的具体实施例中，当一个调度安排发生时，VNF向EMS上报VNF性能管理数据，EMS进行阈值检测后转发至VNFM，此过程中VNFM也会收集VNF相关的性能业务指标(如用户数量、服务的CAPS和SAPS、服务间隔、呼叫持续时间等)，用来作为弹性伸缩的输入条件；同时，VIM从NFVI中采集到的VR性能管理数据，也会上报至VNFM，最后由VNFM进行VNF和VR的性能管理。In a specific embodiment of the present invention, when a scheduling arrangement occurs, the VNF reports the VNF performance management data to the EMS, and the EMS forwards the threshold detection to the VNFM. During this process, the VNFM will also collect VNF-related performance service indicators (such as user Quantity, service CAPS and SAPS, service interval, call duration, etc.) are used as the input conditions for elastic scaling; at the same time, the VR performance management data collected by VIM from NFVI will also be reported to VNFM, and finally VNFM will Performance management for VNFs and VRs.

(2)EMS对VNF性能管理数据和VR性能管理数据的管理过程(2) EMS management process of VNF performance management data and VR performance management data

如图4所示，包括：As shown in Figure 4, including:

步骤41：VNF向对应连接的EMS发送VNF性能管理数据；Step 41: The VNF sends VNF performance management data to the correspondingly connected EMS;

步骤42：EMS从所述VNFM获取与所述VNF相关的第一VR性能管理数据，所述第一VR性能管理数据为与所述EMS连接的VNF所配置的VR的性能管理数据；Step 42: The EMS acquires first VR performance management data related to the VNF from the VNFM, and the first VR performance management data is the performance management data of the VR configured by the VNF connected to the EMS;

步骤43：EMS根据所述VNF性能管理数据以及第一VR性能管理数据，检测VNF的性能数据是否达到预设阈值。Step 43: The EMS detects whether the performance data of the VNF reaches a preset threshold according to the VNF performance management data and the first VR performance management data.

在本发明的具体实施例中，NFVI通过c1接口和c3接口与VIM进行交互，向VIM传递虚拟资源及硬件资源的相关信息，如每个虚拟机及物理机的资源占用率：CPU占用率，内存占用率，网络流出/流入速率，磁盘可用容量和已用容量，磁盘占用率；VIM将信息转发给VNFM，且NFVI中虚拟资源的性能高低直接影响服务质量，具体的，VNFM从所述VIM中获取VR性能管理数据的步骤如图5所示，包括：In a specific embodiment of the present invention, NFVI interacts with VIM through c1 interface and c3 interface, and transmits relevant information of virtual resources and hardware resources to VIM, such as the resource occupancy rate of each virtual machine and physical machine: CPU occupancy rate, Memory occupancy rate, network outflow/inflow rate, disk available capacity and used capacity, and disk occupancy rate; VIM forwards information to VNFM, and the performance of virtual resources in NFVI directly affects service quality. The steps for obtaining VR performance management data in the system are shown in Figure 5, including:

步骤51：VIM获取NFVI中的VR性能管理数据；Step 51: VIM acquires VR performance management data in NFVI;

具体的，所述VR性能管理数据可具体包括：CPU占用率，内存占用率，网络流出/流入速率，磁盘可用容量和已用容量，磁盘占用率；Specifically, the VR performance management data may specifically include: CPU occupancy rate, memory occupancy rate, network outflow/inflow rate, disk available capacity and used capacity, and disk occupancy rate;

步骤52：VIM将获取的VR性能管理数据上报给管理所述VNF的VNFM。Step 52: The VIM reports the acquired VR performance management data to the VNFM that manages the VNF.

所述VNFM进一步按照以下方式触发所述第二请求消息：The VNFM further triggers the second request message in the following manner:

从与所述VNFM连接的虚拟化基础设施管理器VIM中获取VR性能管理数据；Obtain VR performance management data from the virtualization infrastructure manager VIM connected with the VNFM;

从所述VNF中获取VNF性能管理数据；Obtaining VNF performance management data from the VNF;

根据所述VR性能管理数据，判断所述VNF的性能管理数据是否达到预设阈值，并在达到所述预设阈值时，触发所述第二请求消息。According to the VR performance management data, it is judged whether the performance management data of the VNF reaches a preset threshold, and when the preset threshold is reached, the second request message is triggered.

在上述性能管理流程中，当VNF的性能数据达到预设阈值后，相应的VNF的弹性伸缩策略(即扩容或缩容)会被触发，然而，由于VNF的性能管理涉及到EMS和VNFM，当EMS和VNFM同时检测到VNF的性能数据达到阈值之后，都会触发VNF扩容或缩容请求，此时，VNFM就需要有一个仲裁判断的机制，决定请求是否重复来避免潜在的冲突。In the above performance management process, when the performance data of the VNF reaches the preset threshold, the corresponding elastic scaling policy of the VNF (that is, capacity expansion or contraction) will be triggered. However, since the performance management of the VNF involves EMS and VNFM, when After the EMS and VNFM detect that the performance data of the VNF reaches the threshold at the same time, they will both trigger the VNF expansion or contraction request. At this time, the VNFM needs to have an arbitration judgment mechanism to determine whether the request is repeated to avoid potential conflicts.
