Title (EN) FLATTENING L3 ROUTING IN SDN USING PROACTIVE SHORTEST PATH
(FR) OPTIMISATION DE ROUTAGE DE COUCHE L3 DANS SDN À L'AIDE D'UN TRAJET PROACTIF LE PLUS COURT
Abstract:
(EN) A system for network layer (L3) peer-to-peer data packets transfer over a virtual network using proactive mapping of the virtual network, comprising a direct packet carrier of a virtual network connecting a plurality of virtual peers, the direct packet carrier is adapted to receive from a source virtual peer of the plurality of virtual peers one or more data packets destined for a destination virtual peer of the plurality of virtual peers, access a mapping record comprising a plurality of virtual L3 peer-to-peer addresses each mapping a direct peer-to-peer path between a pair of the plurality of virtual peers, retrieve from the mapping record a respective one of the plurality of virtual L3 peer-to-peer addresses mapping the direct peer-to-peer path between the source peer and the destination peer and transfer the data packet(s) to the destination virtual peer using the retrieved virtual L3 peer-to-peer path.
(FR) L'invention concerne un système de transfert de paquets de données entre postes de couche réseau (L3) sur un réseau virtuel à l'aide d'une mise en correspondance proactive du réseau virtuel, comprenant un support de paquet direct d'un réseau virtuel connectant une pluralité de postes virtuels, le support de paquet direct est conçu pour recevoir d'un poste virtuel source de la pluralité de postes virtuels un ou plusieurs paquets de données destinés à un poste virtuel de destination de la pluralité de postes virtuels, accéder à un enregistrement de mise en correspondance comprenant une pluralité d'adresses entre postes L3 virtuels, chacune mettant en correspondance un chemin entre postes direct entre une paire de la pluralité de postes virtuels, récupérer à partir de l'enregistrement de mise en correspondance une adresse respective de la pluralité d'adresses entre postes L3 virtuel mappant le chemin entre postes direct entre le poste source et le poste de destination et transférer le paquet ou les paquets de données au poste virtuel de destination à l'aide du trajet entre postes L3 virtuel récupéré.
