Modeling of Domain-Specific ECA Policies.
Raphael Romeikat, Bernhard Bauer, Henning Sanneck · 2011
Abstract—Policy-based management is a flexible approach for the management of complex systems as policies make context-sensitive and automated decisions. For the effective development of policies it is desired to specify policies at a high level of abstraction initially, and to refine them until they are represented in a machine-executable way. We present an approach that uses models to specify event-condition-action (ECA) policies at different levels of abstraction. A relational algebra is used to specify and validate the models in a formal way. Finally, executable policy code is generated from the lowlevel models. The approach is generic as it can be applied to any domain and supports a flexible number of abstraction layers. It is applied to the network management domain and demonstrated with the modeling and refinement of policies for coverage optimization in a mobile network.
