Policy-Based Service Level Agreement Management System
نویسندگان
چکیده
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.

متن کاملService Level Based Capacity Rationing Procedure for Make-To-Order Manufacturing Systems
We extend a heuristic method within the framework of “dynamic capacity apportionment procedure” (DCAP) to allocate an existing capacity among the classes with different profit contributions. In general, DCAP is applied when some capacity shortage exists and can not be enhanced in short - run. Our proposed approach is constructed for a make - to - order manufacturing system that produces a varie...

We present a policy-based, agent-enhanced resource provisioning architecture, which facilitates flexible and quantitative end-to-end bandwidth reservation and management on a per-user, per-application or per-flow basis. Based on this architecture, various session level Service Level Agreement (SLA) negotiation schemes involving bandwidth allocation, service start time, guaranteed session durati...
متن کاملSelf-aware management of IP networks with QoS guarantees
Self-aware management allows the network to react and to adapt to changes of situation. In this paper an architecture is described for selfaware management of IP networks offering QoS guarantees. This architecture uses policy-based management and multi-agent systems. The originality of the present approach lies in the intention to give a real autonomy to the components intervening in the chain ...
