The invention discloses a service signal transmission method and device, and belongs to the technical field of communication. The method comprises: a first network device obtaining N paths of first service signals, the N paths of first service signals having the same coding type and having at least two paths of first service signals with different transmission rates, N being greater than or equalto 2; inserting a filling signal into the N paths of first service signals to obtain N paths of second service signals, the transmission rates of the N paths of second service signals being integral multiples of a reference rate; and multiplexing the N paths of second service signals into one path of third service signals and sending the third service signals to the second network equipment. By inserting the filling signal into the N paths of first service signals, the N paths of second service signals of which the transmission rates have obvious integer ratio characteristics are obtained, sothat the multiplexing problem of the service signals of different transmission rates is solved, multiplexing transmission of the N paths of first service signals is realized, the transmission efficiency of the service signals is improved, and transmission resources are saved.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a service signal transmission method and device. Background technique [0002] In the current communication network, it is usually necessary to transmit service signals between end-to-end. For example, the networking structure of a communication network usually includes multiple network devices. In a specific service scenario, it is usually necessary to transmit service signals between the first network device and the second network device, wherein the first network device and the second network can be They are any two network devices among the plurality of network devices, and there may be M third network devices (M≥0) between the first network device and the second network device. [0003] In related technologies, for multiple service signals with the same encoding type, the first network device needs to send the multiple service signals to the second netw...
