网管系统中的服务水平管理

Service Level Management in Network Management System

消费者对运营商的选择促使运营商开始对其服务质量进行承诺,导致了服务等级协议(SLA)的产生和发展。在建设新的业务支撑系统时,需要按照SLA管理的思路,在用户业务层、用户网络层、运营商内部业务层、运营商网络层和运营商的其它运营、维护和支撑系统之间建立SLA管理系统。在对已经部署的网管进行改造提供SLA支撑时,需要从服务性能数据收集和分析以及服务故障后服务恢复时间的度量两个方面着手进行。

The selection of operator by consumer impels op erators to make commitment for their service quality,which leads to the generation and development of service level agreement (SLA).When establishing new service support system,SLA management system should be set up between user service layer,user network lay-er,operator's internal service layer,operator's network layer and operator's other operation,maintenance and support system according to the principle of SLA management.When providing SLA support to the modification of the deployed network management system,two aspects should be considered,i.e.:service performance data collection and analysis,service resume time after service failure.<
