An information model for the management of Optical Burst Switched networks

The optical burst switching (OBS) paradigm proposes a new set of transmission protocols and network architectures that permits the high-utilization of the raw bandwidth available by dense wavelength division multiplexing at a moderate computational cost. Accordingly, it is necessary to extend the management plane of such networks to include the particular aspects of OBS, in order to guarantee the appropriate network operation. This paper analyzes the information required for the management of such OBS networks and proposes a new information model based on observed management use-cases. A simple data model is also specified to reduce the computational burden, but compliant with the modeled information.
