Abstract

Current radio access networks are based on tree and star topologies, which have no inherent restorability properties. This paper proposes a heuristic topology enhancement method that adds redundant spans and upgrades existing infrastructure cost-effectively, in order to create partially meshed architectures that can provide the desired level of restorability against single span failures. The algorithm is tested using several different variants of restoration mechanisms. Results show that reasonably good solutions can be achieved in a short time scale. Finally, a service-oriented protection and restoration model is presented. Attributes are defined and used to create differentiated protection classes.
