Telecommunication network management

The domain of autonomic network management, will remain an important playground for SUMO. It covers a wide variety of problems, ranging from distributed (optimal) control to distributed diagnosis, optimization, reconfiguration, provisioning, etc. We have a long experience in model-based diagnosis, in particular distributed (active) diagnosis, and have recently proposed promising techniques for self-modeling. It consists in building the model of the managed network on the fly, guided by the needs of the diagnosis algorithm. This approach allows one to deal with potentially huge models, that are only described by their construction grammar, and discovered at runtime. Another important research direction concerns the management of “multi-resolution” models, that can be considered at different granularity levels. This feature is central to network design, but has no appropriate modeling formalism nor management approaches. This is a typical investigation field for abstraction techniques. Technology is ahead of theory in this domain since networks are already driven or programmed through management policies, that assign high level objectives to an abstract view of the network, leaving open the question of their optimal implementation. As a last topic of investigation, today management issues are no longer isolated within one operator, but range accross several of them, up to the supported services, which brings game theory aspects into the picture.
