Cet article considère le fonctionnement non bloquant à sens large du commutateur optique élastique longueur d'onde-espace-longueur d'onde. Six algorithmes de contrôle, basés sur la décomposition du spectre fonctionnel dans les liaisons inter-étages et la décomposition fonctionnelle des commutateurs centraux, sont proposés pour deux architectures de matrice de commutation. Pour ces algorithmes, nous avons dérivé des conditions non bloquantes au sens large et les avons comparées à des conditions non bloquantes au sens strict. Les résultats montrent que l'algorithme proposé réduit le nombre requis d'unités de créneaux de fréquence (FSU) ou de commutateurs centraux, en fonction de l'architecture de la structure de commutation. Des économies sont réalisées même lorsque les connexions utilisent un petit nombre d'unités de créneaux de fréquence.

Abstract: This paper considers wide-sense nonblocking operation of the Wavelength-Space-Wavelength elastic optical switch. Six control algorithms, based on functional spectrum decomposition in interstage links and functional decomposition of center stage switches, are proposed for two switching fabric architectures. For these algorithms we derived wide-sense nonblocking conditions and compared them with strict-sense nonblocking ones. The results show that the proposed algorithm reduces the required number of frequency slot units (FSUs) or center stage switches, depending on the switching fabric architecture. Savings occur even when connections use small number of frequency slot units.
