Research on Multi-domain Policy-based SLA Management Model

After analyzing the current IP QoS management models and the Policy-based management framework, this paper addresses the topic of constructing a SLA (Service Level Agreement) management model, including model construction, function modules description and related process explanation. On the basis of PBNM (Policy Based Network Management), a multi-domain policy-based SLA management model is presented, which includes three main SLA modules: automatic mapping, admission control and resource configuration. This model embeds SLA management into TP QoS management framework and induces multi-domain management architecture to extend PBNM centralized architecture. Finally, issues to be explored further in the future work are presented.
