Avaliação de Desempenho de estratégias de roteamento e alocação de espectro em redes ópticas metropolitanas elásticas

Abstract

With the emergence of Elastic Optical Networks (EON), an increase in resources in optical communication networks has been foreseen. In the current internet scenario, it is urgent to create technologies that develop a high level of efficiency, in order to meet a global need for connection. EON brought advantages capable of making the use of network resources more flexible and efficient. This work explores this technology and discusses the current state of metro optics in Par ́a. In addition, network and traffic scenarios are implemented in environments that simulate real Metro Optical Networks (ROM). At the end of this research, results are generated that demonstrate the impact of this technology on a large infrastructure considering metrics such as request blocking rate, bandwidth blocking rate, among other fundamental metrics. These results show that a metro network with more connected nodes has a greater advantage in relation to a less connected network, incurring greater efficiency of the available resources.
