Title
(EN) TECHNIQUE FOR ROUTING AND SWITCHING REDUNDANCY
(FR) PROCÉDÉ DE REDONDANCE DE ROUTAGE ET DE COMMUTATION
Abstract
(EN)
A technique for routing datagrams between costumer equipments, CEs, (102) and a pool (110) of broadband network gateways, BNGs, (112) is provided. As to a device aspect (120) of the technique, a first establishing unit (122) is configured to establish a first connection (123) between the device (120) and each of the CEs (102). A second establishing unit (124) is configured to establish a second connection (125) between the device (120) and each BNG (112) in the pool (110) of BNGs (112). A mapping unit (126) is configured to map each of the first connections (123) to one of the second connections (125). The mapping specifies the routing of the datagrams.

L'invention concerne un procédé de routage de datagrammes entre des équipements client, CE, (102) et un groupe (110) de passerelles de réseau à large bande, BNG, (112). Dans un aspect de dispositif (120) du procédé, une première unité d'établissement (122) est configurée pour établir une première connexion (123) entre le dispositif (120) et chacun des CE (102). Une seconde unité d'établissement (124) est configurée pour établir une seconde connexion (125) entre le dispositif (120) et chaque BNG (112) du groupe (110) de BNG (112). Une unité de mappage (126) est configurée pour mapper chacune des première connexions (123) sur l'une des secondes connexions (125). Le mappage spécifie le routage des datagrammes.
