Applying eODL and SDL-Patterns for Developing TMN Managed Systems

摘要

This paper presents how eODL, in combination with SDL-patterns, helps to enhance the ITU-T framework for defining CORBA-based TMN systems. This proposal consists in utilizing eODL, instead of CORBA IDL, incorporating behavior using SDL-patterns. This leads to the following advantages: first, eODL models are described from several points of view, giving more information about the system modeled. Second, the models obtained can be deployed on any Distributed Platform Environment (DPE), not only on CORBA. Third, SDL is a formal language, which is very powerful for modeling the behavior of a system. Furthermore, SDL-patterns provide a more systematic way of describing solutions to a concrete problem than ad hoc SDL. The feasibility of this work is presented with an example.
