    • A system for the prioritization of quality of service (QoS) alerts and the analysis of the impact of such alerts on service uses a service model in which services are broken into one or more service components and sub-components. Creation of a service dependency model, which is driven by different phases of a service, is key to being able to understand how alerts at the lowest level of the network components affect the overall service for which they are but a component. Alerts are assigned a “handle” and a severity level. Rules are defined to be applied to the alerts to create a Component Status Indicator for each component including a handle. As each CSI propagates up towards the top of the service model dependency graph, each CSI gets modified according to predefined rules. A service impact index is created when the CSI is propagated to the top service component. For each service that is impacted, weights (multipler) are defined according to duration of the alert, number of subscribers, number of services, QoS class of the services impacted or other factors defined by user. The weights are used to multiply the SII to obtain the overall impacting index, which is sorted to obtain the priority list. This method can be employed either centrally at a network operations center or in a distributed manner by pre-processing at central offices. Information contained in the handle component of the CSI can be used to perform root cause analysis of the service impacting alerts so as to more efficiently identify and correct problems.
    • 用于优先化服务质量(QoS)警报和对这种警报对服务的影响的分析的系统使用将服务分解成一个或多个服务组件和子组件的服务模型。 创建由服务的不同阶段驱动的服务依赖关系模型是能够理解网络组件最低级别的警报如何影响其所属的整体服务而是组件的关键。 警报被分配一个“句柄”和严重性级别。 规则被定义为应用于警报以为包括句柄的每个组件创建组件状态指示器。 当每个CSI向上传播到服务模型依赖图的顶部时,每个CSI根据预定义的规则被修改。 当CSI传播到顶层服务组件时,创建服务影响索引。 对于受影响的每个服务,根据警报的持续时间,用户数量,服务数量,受影响的服务质量等级或用户定义的其他因素来定义权重(乘数)。 权重用于乘以SII以获得整体影响索引,其被排序以获得优先级列表。 这种方法可以在网络运营中心集中使用,也可以通过在中心局进行预处理以分布式方式使用。 包含在CSI的句柄组件中的信息可用于对服务影响警报进行根本原因分析,以便更有效地识别和纠正问题。
