Abstract

L'invention concerne un procédé et un appareil d'établissement de connexion entre un terminal de ligne optique (OLT) physique et un OLT virtuel. Dans le procédé, un premier terminal de ligne optique physique (pOLT) envoie une demande d'attribution à un terminal de ligne optique virtuel (vOLT) ; conformément à une politique prédéfinie, un serveur virtuel de distribution dans des vOLT sélectionne, parmi au moins une instance de vOLT des vOLT, une première instance de vOLT pour fournir un service au premier pOLT, et envoie des informations de la première instance de vOLT au premier pOLT ; le premier pOLT stocke les informations de la première instance de vOLT pour que le premier pOLT, lorsqu'il enverra une demande de service, l'envoie directement à la première instance de vOLT. Au moyen du procédé décrit, il n'est pas nécessaire que le serveur virtuel de distribution transfère une demande de service à chaque fois qu'elle est envoyée à une instance de vOLT sélectionnée ; ainsi, la quantité de travail effectuée par le serveur virtuel de distribution est réduite, ce qui contribue à améliorer l'efficacité du système et à éviter la limitation de la capacité de service du vOLT en résultat des performances du serveur virtuel de distribution.
