Abstract:
SLA is a negotiated agreement between a customer and the service provider on levels of service characteristics and the associated set of metrics. In this paper, we propose a policy-based SLA management system. We present an approach to react not only when an SLA is violated, but also before imminent SLA violations. We provide a common generic framework capable of components to interwork via XML. The managed SLA metrics are classified into service opening metrics, trouble metrics, and performance metrics. We rely on a proposal for architecture to provide the end-user with SLM from the service subscription to the service termination. Finally, we’ll give an example to illustrate a typical scenario to assure customers’ SLAs in ADSL network service.
