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 wavelength alignment method includes: emitting a first optical signal by using a laser; filtering the first optical signal by using a filter, and then transmitting a second optical signal; monitoring an extinction ratio of the second optical signal and an optical power of the second optical signal; and adjusting a working temperature of the laser and/or a working temperature of the filter to a target working temperature when the extinction ratio of the second optical signal exceeds an upper limit of a first extinction ratio threshold range and the optical power of the second optical signal exceeds a lower limit of a first optical power threshold range or when the extinction ratio of the second optical signal exceeds a lower limit of a first extinction ratio threshold range and the optical power of the second optical signal exceeds an upper limit of a first optical power threshold range.

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.
