摘要： Embodiments of this application relate to a rate adaptation method and apparatus. The method includes: when a rate adaptation requirement exists, inserting a rate adaptation code block only between two adjacent code blocks whose code block relationship meets a preset condition, or deleting only a rate adaptation code block between two code blocks whose code block relationship meets a preset condition. In this way, it can be ensured that correctness of parsing a packet by a receive side after the receive side receives the packet is not affected by rate adaptation, and reliability of rate adaptation can be improved.

摘要： This application discloses a service processing method and apparatus, and belongs to the field of communication technologies. In this application, a unit time period or a unit data frame may be divided into m transmission windows, and then corresponding transmission windows are allocated to each service based on a quantity of transmission windows required by each of n to-be-mapped services to transmit the service. Further, service data of the n services is multiplexed, based on the transmission windows corresponding to each service, into data transmitted in one channel. In this way, a plurality of services may be multiplexed within one time period or in one data frame for service transmission, thereby avoiding a waste of bandwidth resources that occurs because the one time period or the one data frame can carry only one service.

The method includes: obtaining, by a network device, a radio fronthaul interface signal, where the radio fronthaul interface signal includes a plurality of code blocks; mapping the radio fronthaul interface signal to M flexible Ethernet FlexE service layer timeslots to generate a FlexE signal, where the FlexE service layer timeslots are determined based on a rate of the radio fronthaul interface signal, and M is a positive integer greater than or equal to 1; and sending the FlexE signal to one or more physical lanes. The radio fronthaul interface signal such as a CPRI signal, an eCPRI signal, or an NGFI signal is carried by using FlexE, and the FlexE service layer timeslots are divided based on the rate of the radio fronthaul interface signal. Therefore, bandwidth usage of a fronthaul FlexE interface and transmission efficiency of the radio fronthaul interface signal are improved.
