Optical network modeling techniques: A case study

Abstract

From the very beginning of optical networks, there has been a severe lack of analytical techniques enabling effective performance evaluation/prediction for actual networks. The analytical and simulation methods applied have been based on inadequate models. The paper shows the basic inadequacy in the models proposed usually for optical networks, applying so called open system and network approach. The authors propose the approach needed, in particular, for the systems developed in rather poorly countries where the hardware available for the designers was obsolete in comparison to that available in well developed countries. The paper describes some experience in ICT system modeling and the network modeling tool and technique worked out.
