Abstract

L'invention concerne un procédé et un dispositif de traitement de contenu de page, un nœud maître, un nœud esclave et un support de stockage. Le procédé comprend les étapes suivantes : un nœud maître d'un système de diffusion directe acquiert le contenu de page d'une page de protocole de transfert hypertexte (HTTP) dans le système de diffusion vers l'avant ; et le nœud maître envoie le contenu de page au nœud esclave du système de diffusion vers l'avant au moyen d'une multidiffusion ou d'une diffusion, le nœud esclave étant utilisé pour renvoyer, au terminal utilisateur, le contenu de page correspondant à la requête HTTP sous le déclenchement d'une requête HTTP envoyée par le terminal utilisateur. En utilisant la solution technique, le problème dans l'état de la technique associé selon lequel la technique d'accélération de page HTTP ne peut pas s'adapter efficacement au système à largeur de bande limitée est résolu, ce qui permet d'économiser du trafic de largeur de bande, de telle sorte que l'accélération d'accès HTTP de l'utilisateur peut être réalisée là où la consommation de bande passante est réduite.
