Um mecanismo para potencialização da agregação de tráfego em redes ópticas elásticas

Elastic optical networks allow splitting the optical spectrum into frequency slots that can be combined to create channels with defined bandwidth on demand. This flexibility provides greater spectral efficiency over traditional fixed grid optical networks. Traffic aggregation strategies make it possible to achieve even greater efficiency in the use of network resources, reducing the amount of guard bands and the use of transmitters and receivers. This paper proposes a mechanism that, combined with existing resource allocation solutions, enhances the use of elastic network capabilities and traffic aggregation. The study shows that the adoption of the proposed mechanism also contributes to the reduction of bandwidth blocking rates and the gain of energy efficiency.
