RESUMO

The emerging SDH transmission technology provides new opportunities to reshape Transport Networks, enabling telecommunications companies to support modern services required in todays competitive markets. However, this new technology requires a new planning methodology. One approach to satisfy this requirement is to divide the planning process in sucessi ve steps: (1) clustering of central offices, (2) bundling of channels over the equipment network, (3) laying-out of the fiber pairs over the physicall network and, (4) equipment network evolution. This divide-and-conquer approach is imposed by the mathematical complexity of the problem to be solved. Among those steps, it s the Bundling problem the one with higher complexity, and also the one with more cost-implications on metropolitan networks. That s the step where the decision about which are the equipment to be installed and the bit-rates to be used. However, when applied to large metropolitan networks, the bundling mathematical modelling is toa complex to be solved by search techniques. This work presents an heuristic method that has been applied to large networks to obtain quality solutions to the Bundling problem. The heuristic method presented here is Rule-based technique, and it has been applied to Sao Paulo Metropolitan Area, the brazilian largest one.
