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.
