Abstract: An alarm processing method and apparatus is disclosed. Specifically, a mechanism of configuring and detecting an LOF pre-alarm is provided. A detection condition of the LOF pre-alarm is that it is detected that a frame alignment failure lasts for first duration. A detection condition of the LOF alarm is that it is detected that a frame alignment failure lasts for second duration. The second duration is less than the first duration. When detecting the LOF pre-alarm, a network device inserts a first maintenance signal frame. The first maintenance signal frame supports frame alignment. In other words, a network device that receives the first maintenance signal frame may perform normal frame alignment, so that no alarm is reported, for example, the LOF alarm is not triggered.

Abstract: Embodiments of this application provide a signal frame processing method and a related device. A sink node performs delay compensation on a received service, so that delay variation generated in a transmission process of the service can be effectively eliminated. The method in embodiments of this application includes the following steps. First, the sink node receives a signal frame. A payload area of the signal frame is used to bear a target service, and an overhead area of the signal frame includes a node quantity field. Then, the sink node determines, based on the node quantity field, a quantity of nodes through which the target service passes during transmission. Further, the sink node performs delay compensation on the target service based on the quantity of nodes.

Abstract: Embodiments of the present invention disclose a bandwidth adjustment method and a related device, configured to adjust a bandwidth of a first payload subarea included in a transmission frame flexibly. The method of embodiments of this application includes the following steps: First, determine the first payload subarea and a second payload subarea from a payload area of the transmission frame; second, determine that a bandwidth of at least one service does not match a bandwidth of the first payload subarea; finally, adjust the bandwidth of the first payload subarea, where an adjusted bandwidth of the first payload subarea matches the bandwidth of the at least one service.
