Abstract
Two closely related protocols are the standard technology for information transmission in broadband optical networks: the Synchronous Digital Hierarchy (SDH) and its North American equivalent SONET. Unlike systems with unplanned growth, such as those of natural origin or the Internet, these telecommunication networks are strictly planned as rings, meshes, stars or tree-branches structures designed to connect different equipments. In spite of this planification, we have found that the SDH network operated by Telef¿onica in Spain shares remarkable topological properties with other complex networks with different origin. In particular, the telecommunication network displays power-law scaling in the degree distribution of SDH equipments and small-world networks properties. In this work, the complexity observed in the Spanish SDH system is reproduced by two complex networks models. One of them, the ad hoc model, considers real planning directives that take into account geographical and technological variables with the aim to predict the growth of the system or generates policies for future sytem designs. The other model has a completely different philosophy. Based on a single evolutive rule, named compatibility, the Compatibility Attachment Model (CAM) is a generic approach to the complexity of the networks, included the one observed in the SDH system.
