Patent

CA 2566511

A method and apparatus is described for optimized routing in networks that include free space directional link. A free space directional link within a network is monitored at the physical and/or data link layer and a router/routing layer protocol is notified regarding the status o f the monitored free space directional link. By monitoring the transmitted signal at the physical and/or data link layer, the present invention avoids reliance upon less frequent control messages to determine free space directional link status, thereby allowing the router/routing layer o be notified more quickly of, and respond more quickly to, changes in free space directional link status.

Cette invention concerne un procédé et un dispositif d'optimisation de l'acheminement dans des réseaux qui comprennent une liaison spatiale directionnelle libre. Le procédé consiste à surveiller une liaison spatiale directionnelle libre au niveau de la couche physique et/ou de la couche de liaison de données et de notifier un protocole de couche d'acheminement/liaison à propos de l'état de la liaison spatiale directionnelle libre. La surveillance du signal transmis au niveau de la couche physique et/ou de la couche de liaison de données offre l'avantage de ne pas devoir s'appuyer sur des messages de commande moins fréquents pour la détermination de l'état de la liaison spatiale directionnelle libre, ce qui permet de notifier plus rapidement ce état au dispositif/couche d'acheminement et de réagir plus vite aux changement survenus dans l'état de ladite liaison.
