    Abstract: An example exchange method includes: receiving, through a first interface, M bits; after receiving the M bits, receiving M bytes through the first interface, wherein each of the M bits indicates a status of a corresponding byte in the M bytes; encapsulating, based on the M bits corresponding to the M bytes, L bytes of the M bytes to obtain L encapsulated bytes, wherein M and L are integers greater than or equal to 1, and L is less than M; exchanging the L encapsulated bytes to a second interface; decapsulating the L encapsulated bytes to obtain L decapsulated bytes; and sending the L decapsulated bytes through the second interface.

    Abstract: This application discloses a flexible Ethernet group establishment method and a device. The method includes: determining that there are at least M physical layer PHY links; receiving at least M delay test requests sent by a near-end device; determining, by the far-end device, at least M receiving time points at which the at least M delay test requests are received; and determining M PHY links used to establish a flexible Ethernet group, from the at least M PHY links based on the at least M receiving time points, where a delay difference between any two of the M PHY links satisfies a preset delay condition. According to the method in this application, the delay difference between the any two PHY links is accurately determined based on time points at which delay test requests are received over any two PHY links.

    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: Embodiments of the present disclosure provide a method for allocating an external network IP address in NAT traversal, and a device and a system. The method includes: receiving a request message sent by a client and is for establishing a NAT mapping entry corresponding to a connection, where the request message includes a designated external network IP address, and the external network IP address is the same as an external network IP address in a NAT mapping entry corresponding to any connection already established by a same application; and when the NAT mapping entry is established according to the received request message, allocating, according to the designated external network IP address in the request message, an IP address which is the same as the designated external network IP address and used as an external network IP address of the NAT mapping entry to be established.

    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.
