Abstract
-
Optimizing national telecommunication networks for developing countries is one of the most important issues in communication today. Developing countries are falling behind the developed countries because of connection delay and throughput bottleneck. This has a direct effect on worldwide communication because developed countries are competing to export their products and services to the third world. Competition in the telecommunication market and product compatibility promises attractive prices and availability for the developing countries.;In this dissertation the triangle relation between network traffic flow, connectivity, and grade of service in national network has been verified and their interdependability relationships has been measured and evaluated by cost analysis methodology.;This research generated a national network optimizing methodology which yields to the development of a software package to solve national networks existing problems and to increase network performance and capacity with minimum cost and maximum profit. This includes providing methods for identifying the critical locations of high speed switches and presented the optimal topology for both switches and links throughout a cost effect analysis for both fixed cost and running cost of national networks.;The general plan in this study was broken into one, five, and ten years for more efficiency. This break-down makes the general plan more flexible to adapt to changes in telecommunication technology. The three plans can be combined and implemented in either a ten-year period or a sixteen-year period, depending on the availability of funds for these plans. The analysis of the data shows that increasing traffic intensity will reduce cost per minute when SONET is used as a backbone network for ATM switches.;The analysis and results suggested in the study can be used to create a national telecommunication network model for any developing country. Nevertheless, the results can be applied to other small countries, big cities, or sections of large countries.;This study is the first methodology of broadband networks on third world countries where there is a high demand for high speed transmission facilities.
