摘要： Example data transmission methods and apparatus are disclosed. One example method includes receiving a first data packet. When a first ring node detects that a link between the first ring node and a second ring node on a first ring port is faulty, it is determined whether the received first data packet is a wrapped data packet. If the first data packet is a non-wrapped data packet, a second ring port is determined based on the first ring port, the first data packet is wrapped into a wrapped data packet to generate a second data packet, and the second data packet is forwarded through the second ring port.

摘要： Embodiments of this application provide a method for obtaining a target transmission route, a related device, and a system. The method is applied to a flexible Ethernet FlexE networking network and includes: receiving a first message that is sent by a second node for requesting to query for a transmission route of a first FlexE client; and sending a second message to the second node, where a route information entry in the second message includes route information of the FlexE client on each node. Ingress information and egress information that are of a FlexE client on a route node are recorded as a transmission route of each hop. A segment-to-segment transmission route in the FlexE network can be dynamically found in real time, a planned and deployed transmission route is compared with an actually found route, to evaluate a network running status.

摘要： In a data transmission method, each ring network interface is associated with a ring identifier, and a ring-incoming packet carries a ring identifier of a ring network interface through which the packet is first forwarded. When a node in a ring network detects a link fault in a process of transmitting a packet, the node determines, with reference to a ring identifier and a wrapping identifier carried in the packet, to perform wrapping or discard the packet. According to the method, two sub-ring networks of a dual-ring coupled ring network can be allowed to separately implement one time of wrapping.

摘要： A frame processing method and apparatus are provided, to implement selective receiving in a redundant transmission scenario. According to a method, a destination device receives a first Ethernet frame from a first intermediate node through a first interface, where the first Ethernet frame includes a first time point, and the first time point is a processing time point of the first Ethernet frame on the first intermediate node. The destination device receives a second Ethernet frame from a second intermediate node through a second interface, where the second Ethernet frame includes a second time point, and the second time point is a processing time point of the second Ethernet frame on the second intermediate node. The destination device determines, based on the first time point and the second time point, whether the second Ethernet frame is a duplicate frame of the first Ethernet frame.

摘要： Embodiments of this disclosure provide a data transmission method, a device, and a system. The method includes: The first Ethernet interface of the first communications device receives a first packet, and determines whether first indication information in the first packet indicates that the first packet is a multi-fed packet. When the first indication information indicates that the first packet is a multi-fed packet, the first communications device drops the first packet. The first Ethernet interface is an Ethernet interface used by the first communications device for connecting to a second communications device.
