Implementation and evaluation of information models for all-optical networks: an SDL-based approach for rapid prototyping
Guido Carls, Georg Lehr · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
This paper presents an approach that introduces the formal Specification and Description Language (SDL) in the development of TMN systems. Using the management of optical networks as an example it will be outlined how SDL can be used to ease implementation and evaluation of management systems. Owing to the formal nature of SDL system behavior can be specified thoroughly and prototypes can be generated semiautomatically. Applying this approach, dynamic behavior can be evaluated by integrating the generated prototype in an SDL test and simulation environment. In this environment trace tools support description of management interactions in Message Sequence Charts at runtime. Such traces permit to draw conclusions concerning the correctness and proper design of information models. The described methodology is being applied to the development of prototype management applications in the research project MOON. It will be described how existing draft information models (e.g. information models for the management of optical networks) can be evaluated by mapping them to SDL.
