Abstract: A data transmission method includes an access node sends first traffic to a first core network device in a core network through a first service plane of a bearer network. The access node sends second traffic to a second core network device in the core network through a second service plane of the bearer network. The first service plane and second service plane are independent all-active service planes in the bearer network. Service data sent by the base station is split on the access node, and split data each corresponds to one transmission path. Even if one transmission path is completely interrupted, the service data may still be transmitted by another core network device through the other transmission path.

Abstract: A multicast packet transmission method, apparatus, and system, where the method is applied to a multicast ring network and the method includes receiving, by a first network node in the multicast ring network through a first path in a clockwise direction of the multicast ring network, a first multicast packet from a second network node in the multicast ring network, receiving, by the first network node through a second path in an anticlockwise direction of the multicast ring network, a second multicast packet from the second network node, where a payload of the first multicast packet is the same as a payload of the second multicast packet, and forwarding, by the first network node, the first multicast packet or the second multicast packet to at least one multicast destination device connected to the first network node.

Abstract: A method includes determining a transmission path. The method includes determining, by a first node, a first candidate path group that includes at least one first candidate path. when the first candidate path group includes at least two first candidate paths, The method further includes selecting a first path from the at least one first candidate path according to a preset first rule based on node information of each of the first candidate paths in the first candidate path group. The method further includes determining that the first path is a transmission path and when a source node of the first path is the first node, or determining that the second path is the transmission path when the source node of the first path is a second node, where the second path is a reverse path of the first path.
