Abstract

La présente invention, qui relève du domaine des communications optiques, divulgue un procédé et un appareil de traitement de données, un dispositif de réseau et un système de communication. Le procédé comprend : lorsqu'un premier terminal de réseau optique (ONT) satisfait une condition de déclenchement de sauvegarde de données, l'établissement d'un canal de transmission entre le premier terminal ONT et un terminal de ligne optique (OLT) ; et l'envoi, par le premier terminal ONT, de données d'utilisateur au terminal OLT sur la base du canal de transmission, le terminal OLT, en tant que support de transfert, stocke les données d'utilisateur de sorte qu'un second terminal ONT acquiert les données d'utilisateur auprès du terminal OLT. Par conséquent, lorsqu'un terminal ONT satisfait une condition de déclenchement de sauvegarde de données, des données d'utilisateur du terminal ONT sont sauvegardées à l'aide d'un terminal OLT de sorte qu'une occasion de transmission de données peut être déterminée avec précision et, ainsi par comparaison à un procédé de stockage en nuage, le procédé selon la présente invention peut améliorer efficacement la fiabilité de stockage de données au moyen d'un transfert automatique. De plus, selon le procédé décrit dans la présente demande, un transfert de données est réalisé à l'intérieur d'un réseau ayant le terminal OLT et le terminal ONT, de sorte que la sécurité de stockage des données peut être efficacement améliorée.
