Abstract

L'invention concerne un procédé et un appareil de gestion collective de la bande passante d'un terminal de réseau optique passif. Le procédé consiste : à acquérir des données de requête envoyées par une unité de réseau optique, les données de requête comprenant des données de message de réunion en diffusion groupée ou des données de message de sortie en diffusion groupée ; à déterminer si les données de requête satisfont une condition d'application de service de diffusion groupée prédéfinie ; si les données de requête satisfont la condition d'application de service de diffusion groupée, à ajuster une bande passante de transmission de données d'envoi individuel selon des données de configuration prédéfinies d'une bande passante de transmission de données de diffusion groupée, et gérer la bande passante de transmission de données de diffusion groupée. Sur la base du non changement de l'architecture matérielle d'un dispositif de réseau existant, des bandes passantes de données d'envoi individuel et de diffusion groupée d'une unité de réseau optique peuvent être gérées collectivement au moyen d'un terminal de ligne optique, ce qui permet de simplifier le procédé de gestion collective de la bande passante d'un terminal de réseau optique passif, et de réduire le coût de résolution du problème d'incapacité de gérer collectivement la bande passante d'un terminal de réseau optique passif.
