Abstract

L'invention porte sur un nœud mobile (MN) à protocole de séparation identificateur/localisateur (LISP), un procédé de gestion de mouvement et un nœud mobile, le procédé consistant à : après qu'un mouvement a été effectué par le MN LISP et qu'un nouveau localisateur de routage (RLOC) a été obtenu, envoyer une requête de mise à jour de correspondance entre identificateur d'extrémité (EID) et RLOC à un nœud correspondant. Après que le mouvement a été effectué, le MN LISP notifie à temps au nœud correspondant de mettre à jour la correspondance entre EID et RLOC, assurant que le nœud correspondant utilise directement le nouveau paquet de données RLOC encapsulé et envoie des données durant la transmission de données subséquente, ce qui réduit le retard et la perte de paquets.
