RESUMO

The objective of this work is to develop computational tools to create an environment that permits to search for optimal topologies to interconnect multimedia network nodes. The searching process uses links parameters, based on the amount of transported traffic and also reliability, cost and distance between nodes. The optimal topology is the one that fulfills the requirements of minimal reliability, maximum link load, maximum buffer delay and maximum packet loss, defined by the network planner. The calculus of packet loss and delay are based on the Poisson and self-similar models. The tool used in the optimization process is a mono-objective genetic algorithm, that aloud in this context, evaluate a smaller number of options and find a optimal or sub-optimal solution. The experiments made with different network configurations and their results validate the proposed methodology, showing the possibility of application of this tool in real networks with a low computational cost.
