Proteção de Redes Ópticas Elásticas com Multiplexação Espacial Baseada em Agregação de Tráfego, Sobreposição de Espectro e Compartilhamento de Caminho de Backup
Abstract
The introduction of space division multiplexing (SDM) in optical networks brings new challenges for network protection, since a light path can span multiple cores. In this article, we investigate the problem of dynamic protection against simple faults in optical networks using spatial division multiplexing. For this, we propose a new path protection algorithm by performing optical traffic grooming and spectrum overlap. In the Spectrum, Backup, Routing and Core assignment (SBRC) algorithm, each connection is assigned to a primary path and a backup path.
