Abstract: 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.

Abstract: The present disclosure relates to operation, administration and maintenance (OAM) data transmission methods and apparatus. One example method includes obtaining a first data flow of a client, inserting an OAM data block in the first data flow of the client to obtain a second data flow of the client, where the OAM data block is a 64B/66B code block that carries OAM data, and distributing the second data flow of the client to at least one slot of a channel corresponding to the client.

Abstract: This application provides an example delay measurement method and an example network device. The method includes receiving, by a first network device, a first service flow. The method also includes determining, by the first network device, a first delay value based on a first measurement code block in the first service flow. The first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device.

Abstract: A method applicable to a commonest application scenario, the method includes: an AR receives a first packet sent in a unicast manner by a CGN. The first packet includes information for indicating Restart announce, the first packet's source address is the CGN's address, and the first packet's destination address is the AR's address; AR changes the first packet's destination address to an address of a CPE connected to the AR, to obtain a second packet, where the AR and the CPE are connected by using a Layer 2 network, and the CPE's address is a multicast address; and the AR sends the second packet. The method is used for quickly informing, after the CGN restarts or undergoes an active/standby switchover, the CPE that an exception occurs, for example, the CGN restarts or undergoes an active/standby switchover, so that a CGN has relatively small load when recreating NAT mapping.

Abstract: A troubleshooting method, a device, and a readable storage medium are provided, to detect a unidirectional fault in a ring Ethernet and provide a fault recovery mechanism after the unidirectional fault occurs. In embodiments of this application, if determining that a link corresponding to a receiving unit of a first port is in a fault status, the first device performs loopback on the first port, and sends a first continuity check message to a second device via the first port. The first continuity check message carries first indication information. The first indication information indicates that a link corresponding to a receiving unit of a port that sends the first indication information is in a fault status.

Abstract: A frame processing method and apparatus are provided, to implement selective receiving in a redundant transmission scenario. The method includes: 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.

Abstract: Embodiments of the present invention disclose a service multiplexing method. The method includes: sending, by a sending device, a bit block stream of a first service to a receiving device; if the sending device determines to switch from the first service to a second service for service sending, sending, by the sending device, at least one service switching indication bit block to the receiving device; and sending, by the sending device, a bit block stream of the second service to the receiving device. In addition, a service switching indication bit block is inserted between bit block streams that require service switching, to perform service switching, thereby reducing a latency and jitter in a service switching process, and ensuring a low latency during service switching.
