Abstract: A first device generates a first capability model instance based on a capability model template, and sends the first capability model instance to a network management device. The capability model template includes one or more metric names. The first capability model instance includes one or more performance parameters that can be subscribed to by the first device, and the one or more performance parameters are parameters corresponding to one or more metric names. The first capability model instance is used by the network management device to select and subscribe to one or more performance parameters from the one or more performance parameters that can be subscribed to by the first device.

Abstract: A fiber applied to an optical amplifier, where the fiber includes a rare earth-doped core and a cladding. The core includes a gain equalization unit. The core is configured to separately amplify optical signals of all wavelengths in a received multiplexing wave. The gain equalization unit is configured to equalize gains of the optical signals of all the wavelengths, such that gains of optical signals that are of all the wavelengths and that are transmitted from an egress port of the fiber all fall within a preset range, The gain of the optical signal of each wavelength in the optical signals of all the wavelengths is determined based on a ratio of power of an amplified optical signal to power of the unamplified optical signal.

Abstract: An optical amplifier includes at least two stages of optical amplifier systems, an optical switch, a dynamic gain equalizer (DGE), and a control circuit. An input end of the optical switch is separately coupled to an output end of a first-stage optical amplifier system and an output end of a second-stage optical amplifier system, and an output end of the optical switch is separately coupled to an input end of the second-stage optical amplifier system and an input end of the DGE. The optical switch is configured to set at least two gain modes of the optical amplifier. The control circuit is configured to adjust an attenuation spectrum of the DGE based on the at least two gain modes set by the optical switch. The DGE is configured to perform, based on an adjusted attenuation spectrum, power attenuation processing on signals of different wavelengths in a received optical signal.

Abstract: A mobile terminal includes a middle frame, a battery cover, and a display. A first groove and a second groove are provided on each of a left-side wall and a right-side wall of the middle frame, and the first groove and the second groove share a part of the side wall. The display is disposed in one of the first grooves, and the battery cover is disposed in one of the second grooves. The display includes an obverse-side display area and two arc-shaped display areas located on two sides of the obverse-side display area, indent surfaces of the two arc-shaped display areas are disposed opposite to each other, and a vertical distance between end portions of the two arc-shaped display areas that are away from the obverse-side display area is less than a maximum vertical distance between the two arc-shaped display areas.

Abstract: A method includes receiving, by a first network device, a first packet and a second packet, where the first packet and the second packet belong to first traffic, and all packets included in the first traffic match a first traffic differentiation rule; based on a mapping relationship between the first traffic and a first encryption policy group, encrypting, by the first network device, the first packet using a first encryption policy to obtain a third packet, and encrypting, by the first network device, the second packet using a second encryption policy to obtain a fourth packet, where the first encryption policy group includes the second encryption policy and the first encryption policy, and the first encryption policy and the second encryption policy are different encryption policies; and sending, by the first network device, the third packet and the fourth packet to a second network device.
