A Scalable Monitoring Approach for Service Level Agreements Validation
In order to detect violations of end-to-end service level agreements (SLA) and to isolate trouble links and nodes based on a unified framework, managers of a service provider network need to gather Quality of Service (QoS) measurements from multiple nodes in the network. For a network carrying over thousands of flows with end-toend SLAs, the information exchanged between network nodes and a central network management system (NMS) could be substantial. Moreover, in situations where only a small number of flows violate their respective SLAs, simple polling mechanisms can lead to huge unnecessary overhead in identifying these ill-behaved flows. In this work, we propose an algorithm called ARM (Aggregation and Refinement based Monitoring) to reduce the amount of information exchange. ARM uses a histogram-based dynamic QoS data aggregation/refinementtechnique at each network node and a reasoning engine at the NMS to minimize the amount of data exchange between network nodes and NMS. ...
