(FR) PROCÉDÉ ET APPAREIL DE SAUVEGARDE POUR UN BRAS AYANT UN PLAN DE TRANSFERT ET UN PLAN DE COMMANDE SÉPARÉS
(ZH) 一种BRAS转控分离的备份方法和装置
Abstract:
(EN) The present application provides a backup method and apparatus for a BRAS having separated forwarding plane and control plane. The method comprises: after user equipment passes authentication, determining session information corresponding to the user equipment, and determining a tunnel backup group corresponding to the user equipment, the tunnel backup group comprising a primary tunnel between a BRAS-CP device and a primary BRAS-UP device and a backup tunnel between the BRAS-CP device and a backup BRAS-UP device; sending, by means of the primary tunnel, the session information to the primary BRAS-UP device, so that the primary BRAS-UP device transmits data according to the session information; and if the primary BRAS-UP device fails, acquiring session information corresponding to the primary BRAS-UP device, and sending, by means of the backup tunnel, the acquired session information to the backup BRAS-UP device, so that the backup BRAS-UP device transmits data according to the received session information.
(FR) La présente invention concerne un procédé et un appareil de sauvegarde pour un serveur d'accès à distance à large bande (BRAS) ayant un plan de transfert et un plan de commande séparés. Le procédé consiste à : déterminer, après que l'authentification d'un équipement d’utilisateur a réussi, des informations de session correspondant à l'équipement d’utilisateur, et déterminer un groupe de sauvegarde de tunnel correspondant à l'équipement d’utilisateur, le groupe de sauvegarde de tunnel comprenant un tunnel primaire entre un dispositif de plan de commande (CP) de BRAS (BRAS-CP) et un dispositif de plan utilisateur (UP) de BRAS (BRAS-UP) primaire, et un tunnel de sauvegarde entre le dispositif BRAS-CP et un dispositif BRAS-UP de sauvegarde ; envoyer les informations de session au dispositif BRAS-UP primaire, via le tunnel primaire, de telle sorte que le dispositif BRAS-UP primaire transmette des données d’après les informations de session ; et, en cas d'échec du dispositif BRAS-UP primaire, acquérir des informations de session correspondant au dispositif BRAS-UP primaire, et envoyer les informations de session acquises au dispositif BRAS-UP de sauvegarde, via le tunnel de sauvegarde, de telle sorte que le dispositif BRAS-UP de sauvegarde transmette des données d’après les informations de session reçues.
(ZH) 本申请提供一种BRAS转控分离的备份方法和装置,该方法包括:在用户设备通过认证后,确定所述用户设备对应的会话信息,并确定所述用户设备对应的隧道备份组,所述隧道备份组包括BRAS-CP设备与主BRAS-UP设备之间的主隧道、BRAS-CP设备与备BRAS-UP设备之间的备隧道;通过所述主隧道将所述会话信息发送给所述主BRAS-UP设备,以使所述主BRAS-UP设备根据所述会话信息进行数据传输;若所述主BRAS-UP设备发生故障,则获取与所述主BRAS-UP设备对应的会话信息,并通过所述备隧道将获取的会话信息发送给所述备BRAS-UP设备,以使所述备BRAS-UP设备根据接收到的会话信息进行数据传输。
