Abstract
(EN)
The multicast traffic transmission method comprises: detecting (S201) whether a transmission link between a DF and a traffic receiving device is abnormal; and when the transmission link between the DF and the traffic receiving device is abnormal, sending (S202) a first request to a BDF, wherein a message of the first request contains a protective mark, and address information about the traffic receiving device, and the first request is used for requesting the BDF to forward traffic to the traffic receiving device.
(FR)
Le procédé de transmission de trafic de multidiffusion consiste : à détecter (S201) si une liaison de transmission entre un DF et un dispositif de réception de trafic est anormale ; et, lorsque la liaison de transmission entre le DF et le dispositif de réception de trafic est anormale, à envoyer (S202) une première demande à un BDF, un message de la première demande contenant une marque de protection, et des informations d'adresse concernant le dispositif de réception de trafic, et la première demande est utilisée pour demander au BDF de transmettre le trafic au dispositif de réception de trafic.
(ZH)
一种组播流量传输方法包括:检测(S201)DF与流量接收设备之间的传输链路是否异常;当所述DF与所述流量接收设备之间的传输链路异常时,向BDF发送(S202)第一请求,所述第一请求的报文中包含保护标记和所述流量接收设备的地址信息,所述第一请求用于请求所述BDF向所述流量接收设备转发流量。
