Abstract: Embodiments of the present application disclose a point-to-multipoint service transmission method and apparatus. The first node is connected to the second node by using a first additional path, and the first additional path and a second path constitute a first protection path. The second node is connected to the first node by using a second additional path, and the second additional path and a first path constitute a second protection path. The method may include: when the first node is in an active state and the second node is in a standby state, receiving, by the first node by using the first protection path if the first path is faulty, service data sent by the root node; and forwarding, by the first node, the service data to the multiple leaf nodes.

Abstract: A method, an apparatus and a system for interconnected ring protection, relates to the communication field, realizes the protection of the interconnected ring network using a narrow bandwidth, and improves the bandwidth utilization rate. The method comprises: a first intersection node in an intersection node group receiving an cross-ring service, the first intersection node determining an off-ring node of the cross-ring service on a second ring according to service information of the cross-ring service; and if the first intersection node does not communicate with the off-ring node of the cross-ring service on the second ring, and the first intersection node is not the last intersection node, the first intersection node forwarding the cross-ring service to a second intersection node.
