Abstract:
(EN) Provided in the present invention are a packet forwarding method and apparatus. According to one embodiment of the method, when receiving an uplink Q-in-Q protocol packet by means of a port connected to an access device, an ESGW device forwards the uplink Q-in-Q protocol packet to a vBRAS device by means of a virtual extensible local area network VXLAN tunnel between the ESGW device and the vBRAS device; when receiving an uplink Q-in-Q data packet by means of the port connected to the access device, the ESGW device strips the Q-in-Q tag off the uplink Q-in-Q data packet, determines that the target MAC address of the uplink Ethernet data packet after the Q-in-Q tag is stripped off is the MAC address of ESGW device, and performs layer 3 forwarding on the basis of the target IP address of the uplink Ethernet data packet.
(FR) La présente invention concerne un procédé et un appareil de transmission de paquet. Selon un mode de réalisation du procédé, lors de la réception d'un paquet de protocole Q-in-Q de liaison montante au moyen d'un port connecté à un dispositif d'accès, un dispositif ESGW transmet le paquet de protocole Q-in-Q de liaison montante à un dispositif vBRAS au moyen d'un tunnel VXLAN de réseau local extensible virtuel entre le dispositif ESGW et le dispositif vBRAS ; lors de la réception d'un paquet de données Q-in-Q de liaison montante au moyen du port connecté au dispositif d'accès, le dispositif ESGW supprime l'étiquette Q-in-Q du paquet de données Q-in-Q de liaison montante, détermine que l'adresse MAC cible du paquet de données Ethernet de liaison montante après que l'étiquette Q-in-Q est supprimée est l'adresse MAC du dispositif ESGW, et effectue une transmission de couche 3 en fonction de l'adresse IP cible du paquet de données Ethernet de liaison montante.
(ZH) 本发明提供一种报文转发方法及装置。根据该方法的一个示例,ESGW设备通过连接接入设备的端口接收到上行Q-in-Q协议报文时,通过所述ESGW设备与vBRAS设备之间的虚拟可扩展局域网VXLAN隧道将所述上行Q-in-Q协议报文转发至所述vBRAS设备;ESGW设备可通过连接所述接入设备的端口接收到上行Q-in-Q数据报文时,剥掉所述上行Q-in-Q数据报文的Q-in-Q标签,确定剥掉所述Q-in-Q标签后的上行以太网数据报文的目的MAC地址为所述ESGW设备的MAC地址,根据所述上行以太网数据报文的目的IP地址进行三层转发。
