摘要： An optical signal amplification apparatus includes a power detection module, a pump control module, and a Raman amplification module. The power detection module is configured to detect power of each of a plurality of G wavelength channels in each of a plurality of N spatial dimensions, and send power configuration information to the pump control module. The pump control module is configured to output N channels of pump light, where each channel of pump light includes M pieces of split pump light of different wavelengths, and a proportion of each piece of split pump light in pump light of a corresponding wavelength is determined based on the power configuration information. The Raman amplification module is configured to perform Raman amplification on a space division multiplexed signal in all of the N spatial dimensions by using the N channels of pump light.

摘要： A wireless local area network (WLAN) association method and device and a central access point (AP), where the method includes receiving, by the central AP, a plurality of association requests, where the plurality of association requests are from at least two APs, and the plurality of association requests have a same basic service set identifier (BSSID), selecting, by the central AP, one association request from the plurality of association requests as a to-be-replied association request, and sending, by the central AP, a first association response to a to-be-associated AP, where the first association response is a reply to the to-be-replied association request, and the to-be-associated AP is an AP in the at least two APs that sends the to-be-replied association request. Only a to-be-associated AP provides a service for a terminal such that a possibility of conflict occurrence is reduced.

摘要： An access point (AP) energy saving method and an AP relate to the field of communications technologies, and effectively implement energy saving for the AP. The method includes determining that an AP is not associated with any terminal and there is not any to-be-associated terminal within a preset time segment, and turning off, by the AP, an extended radio frequency circuit, where an operating frequency band of the extended radio frequency circuit is a wireless local area network (WLAN) frequency band other than a 2.4 gigahertz (GHz) frequency band.

摘要： A multicast service processing method and an access point are disclosed. The method includes: generating, by an access point (AP), a first group addressed frame and an individually addressed frame based on a multicast packet, where the first group addressed frame is encrypted by a first multicast key, and the individually addressed frame is encrypted by a unicast key of a second terminal.

摘要： A method for setting a packet transmission mode and a device are provided, and relate to the communications field. To optimize sending of a multicast packet, both robustness and resource consumption are considered. A specific solution is as follows: when a packet amount in a packet cache queue exceeds a first threshold, changing a state of a first multicast group to multicast transmission, where a state that is of the first multicast group and that is before the change is multicast-to-unicast transmission. Technical solutions of this disclosure are used for setting a packet transmission mode.
