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 data transfer method and a virtual switch, where when receiving a data packet, the virtual switch extracts characteristic information of the data packet, and determines, based on the extracted characteristic information of the data packet, whether an expedited forwarding rule is configured for a data stream to which the data packet belongs. If the expedited forwarding rule is configured for the data stream to which the data packet belongs, the virtual switch bypasses a LINUX bridge to directly send the data packet to a receive end, thereby reducing times of data packet switching between a kernel mode and a user mode, and improving data packet forwarding efficiency.

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 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.

Abstract: Embodiments provide a protection switching method and system, a network device, and related communications technologies. In various embodiments, if n links carrying a client service are unavailable in a FlexE link group, at least one protection link can be selected, by a first network device, from links other than the n links in the FlexE link group. A calendar request can be sent, by the first network device, to a second network device over the protection link. A calendar acknowledge can be sent by the second network device over the protection link and can be received, by the first network device. A transmission of the client service can be switched over from the n links to the protection link. In the present invention, an application requirement of the FlexE for protection switching is satisfied.
