Abstract

L'invention concerne un procédé de poussée de données. Le procédé de poussée de données consiste à : lors de la réception d'une requête de service envoyée par un terminal d'utilisateur, déterminer, par un nœud de réseau de livraison de contenu (CDN), si des données de service indiquées par la requête de service sont mémorisées à l'heure actuelle ou non ; lorsque les données de service indiquées par la requête de service ne sont pas mémorisées à l'heure actuelle et que les données de service indiquées par la requête de service comportent un localisateur de ressources uniforme (URL) redirigé, acquérir, par le nœud CDN et sur la base de l'URL redirigé, des données de service qui ne comportent pas l'URL redirigé ; mémoriser, par le nœud CDN, les données de service qui ne comportent pas l'URL redirigé en tant que données de service indiquées par la requête de service et envoyer les données de service qui ne comportent pas l'URL redirigé au terminal d'utilisateur ; et lorsque les données de service indiquées par la requête de service sont mémorisées à l'heure actuelle, envoyer directement, par le nœud CDN, les données de service indiquées par la requête de service au terminal d'utilisateur. L'invention concerne également un appareil de poussée de données. La présente invention peut améliorer l'efficacité d'acquisition de données d'un terminal d'utilisateur.
