Title
(EN) HOST-ROUTER VIRTUAL TUNNELING
(FR) TUNNELLISATION VIRTUELLE DE ROUTEUR-HÔTE ET GESTION DE TUNNELS MULTIPLES
Abstract
(EN)
A virtual tunnel method is described herein which implemented by a host and next hop routers to address a problem that is related to synchronizing active tunnel(s) and active link(s) between the host and next hop routers.
(FR)
Un procédé de tunnel virtuel est décrit lequel est mis en œuvre par des routeurs hôte et de saut suivant pour adresser un problème lié à la synchronisation de tunnel(s) actif(s) et de liaison(s) active(s) entre les routeurs hôte et de saut suivant. En outre, un procédé de gestion de tunnels multiples est décrit, lequel est mis en œuvre par un hôte pour adresser le problème lié à la synchronisation de tunnel(s) actif(s) et liaison(s) active(s) entre les routeurs hôte et de multiples sauts suivants.
