Uma proposta de plataforma de simulação para estudo do protocolo ENUM

Abstract

IP networks have become an increasingly protable option over traditional communication networks. Despite the advantages of VoIP compared to PSTN, it is not possible to replace one technology by the other instantly, due to the complexity involved. This implies a transition period in which the two technologies will coexist. In order to make this feasible, there must be a system for mapping E.164 numbers (used in the PSTN) to URIs (used in the IP network). In this context, the ENUM protocol is gaining prominence as the most promising solution. However, it is not very spread yet. In addition, there are technical issues and especially political and economic interests that need to be worked so that this protocol can be popularized. Regarding technical issues, there is a shortage of tools for the study of this protocol. Thus, this dissertation proposes a simulation platform that enables the study of the ENUM protocol. The project design of the simulator was based on experiments carried out in the laboratory, the proposition of mathematical models and, subsequently, implementation, integration and validation of the simulator. The results indicate that the simulation platform rightly describes the real system considered. The results also proved the success of the proposed modeling strategy. In addition, new modules were developed for the NS-3 simulation environment, oering new opportunities for researchers.
