Title
(EN) COMPUTER SYSTEM FABRIC SWITCH HAVING A BLIND ROUTE
(FR) COMMUTATEUR MATRICIEL DE SYSTÈME INFORMATIQUE AYANT UNE ROUTE AVEUGLE
Abstract
(EN)
A fabric switch includes ports, a blind route determination function component, a location function component, and a routing function component. Packets are received and forwarded via the ports. The blind route determination function component determines whether a port at which a packet is received is configured for a blind route, the location function component provides for determining a location of routing information within the packet based at least in part on the input port at which the packet was received if a blind route is not defined for the port. The routing function component provides for determining an output port as a routing function based at least in part on the contents of the location, or the existence of a blind route.
(FR)
L'invention concerne un commutateur matriciel comprenant des ports, un composant de fonction de détermination de route aveugle, un composant de fonction de localisation et un composant de fonction de routage. Des paquets sont reçus et transmis par l'intermédiaire des ports. Le composant de fonction de détermination de route aveugle détermine si un port au niveau duquel un paquet est reçu est configuré pour une route aveugle, le composant de fonction de localisation permet de déterminer un emplacement d'informations de routage à l'intérieur du paquet sur la base, au moins en partie, du port d'entrée au niveau duquel le paquet a été reçu si une route aveugle n'est pas définie pour le port. Le composant de fonction de routage sert à déterminer un port de sortie comme une fonction de routage sur la base, au moins en partie, du contenu de l'emplacement, ou l'existence d'une route aveugle.
