A method and apparatus for optimally routing a data packet through multiple autonomous networks. A data packet received at an ingress node of a first autonomous network is routed to an egress node of a second autonomous network by selecting an optimal route based on the lowest latency using internal gateway protocol (IGP) routing information of the first and second autonomous networks, which is distributed to nodes of the first and second autonomous network. The data packet is then transmitted along the selected optimal route.

L'invention concerne un procédé et un appareil pour router de manière optimale un paquet de données à travers des réseaux autonomes multiples. Un paquet de données reçu au niveau d'un nAEud d'entrée d'un premier réseau autonome est routé vers un nAEud de sortie d'un second réseau autonome en sélectionnant un trajet optimal sur la base de la latence la plus faible à l'aide d'informations de routage d'un protocole de passerelle interne (IGP) des premier et second réseaux autonomes, qui sont distribuées à des nAEuds des premier et second réseaux autonomes. Le paquet de données est ensuite transmis sur le trajet optimal sélectionné.
