服务等级协议SLA测量系统及测量方法Service Level Agreement SLA Measuring System and Measuring Method

技术领域technical field

本申请属于移动通信技术领域，尤其涉及一种服务等级协议SLA测量系统及测量方法。The application belongs to the technical field of mobile communication, and in particular relates to a service level agreement (SLA) measurement system and measurement method.

背景技术Background technique

服务网络具备较强的鲁棒性、可扩展性和容错性，为了更好的服务于用户，在服务提供方和用户之间通过定义服务等级协议(Service LevelAgreement，SLA)来保证服务的执行。The service network has strong robustness, scalability, and fault tolerance. In order to better serve users, a service level agreement (Service Level Agreement, SLA) is defined between the service provider and the user to ensure the execution of the service.

当前SLA测量方式主要包括主动测量方式和被动测量方式。Current SLA measurement methods mainly include active measurement methods and passive measurement methods.

主动测量方式是在客户前置设备(Customer Premise Equipment，CPE)下挂硬件探针，以获取SLA测量数据，实现机制是在探针里向目标应用发起拨测任务，获取网络SLA测量数据，推送至测量管理服务端，对测量数据处理和计算形成SLA测量数据；该种方式需要部署较多探针，成本较高，安装施工和系统运行维护工作量大，且对边缘云移动类CPE设备下挂硬件探针不方便，难以实施。The active measurement method is to hang a hardware probe under the Customer Premise Equipment (CPE) to obtain SLA measurement data. The implementation mechanism is to initiate a dial-up test task to the target application in the probe to obtain network SLA measurement To the measurement management server, the measurement data is processed and calculated to form SLA measurement data; this method needs to deploy more probes, the cost is high, the workload of installation and construction and system operation and maintenance is heavy, and the mobile CPE equipment on the edge cloud Hanging hardware probes is inconvenient and difficult to implement.

被动测量方式是基于深度报文检测(Deep Packet Inspection，DPI)数据分析计算获取SLA测量数据，实现机制是在边缘云侧对N3接口消息采集获取用户面数据，在核心网侧对N1、N2接口消息采集获取用户信令面数据，将信令面的相关信息实时关联回填至用户面数据中，再纳入无线、传输侧的网管数据，运用大数据平台对海量DPI数据汇聚计算出SLA测量数据；该种方式需要采集大量核心网信令面和边缘云的用户面数据，数据规模和计算需求量都很大，需大数据实时计算资源和大带宽传输DPI数据，计算得到各网络分段指标数据，再合成端到端网络测量指标数据，与实际端到端直接测量存在偏差，另外对客户安全要求数据不出园限制的场景无法支持实现。The passive measurement method is based on deep packet inspection (Deep Packet Inspection, DPI) data analysis and calculation to obtain SLA measurement data. The message collection obtains the user signaling plane data, correlates the relevant information of the signaling plane into the user plane data in real time, and then incorporates the network management data of the wireless and transmission sides, and uses the big data platform to aggregate massive DPI data to calculate the SLA measurement data; This method needs to collect a large amount of data on the signaling plane of the core network and the user plane of the edge cloud. The data scale and computing requirements are large. It requires big data real-time computing resources and large bandwidth to transmit DPI data, and calculates the index data of each network segment. , and then synthesize the end-to-end network measurement index data, which deviates from the actual end-to-end direct measurement. In addition, scenarios where customer security requires data to be out of the park cannot be supported.
