CA 2235029

An internetwork relay system and method for transmitting IP traffic including an edge and a core. The edge includes an ingress and egress routers and the core includes a switch network. The ingress router communicates with and receives an IP packet from a source network. The ingress router attaches to each IP packet, a globally unique label which is used to forward the IP packet across the network. The relay switch network communicates with the ingress router, receives the IP packet from the ingress router and forwards the IP packet along its transmission path based on destination information included in its attached label. The egress router receives the IP packet from the switch network and forwards it to a destination network. Once received, the destination network forwards the IP packet to its intended destination.

Système de relais inter-réseaux et méthode de transmission du trafic IP comportant une partie périphérique et une partie centrale. La partie périphérique comprend des routeurs d'entrée et de sortie, et la partie centrale inclut un réseau de commutation. Le routeur d'entrée communique avec un réseau source dont il reçoit un paquet IP, puis fixe à chaque paquet IP une étiquette générale unique qui sert à acheminer ce dernier sur tout le réseau. Le réseau de commutation à relais communique avec le routeur d'entrée, en reçoit le paquet IP et achemine ce dernier le long de son trajet de transmission selon les renseignements de destination indiqués sur son étiquette. Le routeur de sortie reçoit le paquet IP provenant du réseau de commutation et le transfère à un réseau destination qui, une fois le paquet reçu, l'achemine jusqu'à sa destination déterminée.
