Method for service transmission and device for service transmission

Abstract

The invention relates to the technical field of communication and provides a method for service transmission and a device for service transmission. The method for service transmission comprises the following steps: mapping received different types of services to a service adaptation layer data frame in a unified form; further classifying the service adaptation layer data frame, packaging the same type of service adaptation layer data frames into a channel layer data frame, and acquiring corresponding types of channel layer data frames; receiving bandwidth allocation information of each service port, and acquiring the number and time slot positions of the channel layer data frames; and further packaging the channel layer data frames to acquire physical layer data frames according to the number and time slot positions of the channel layer data frames, terminating and reproducing the overhead of the physical layer data frames, and transmitting the physical layer data frames. The method for service transmission and the device for service transmission simplify the intermediate processing process, realize the simplicity, save the cost, and realize dynamic bandwidth control.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a service transmission method and a service transmission device. Background technique [0002] Today's networks carry a variety of services, such as voice, video, online games, and web browsing. As the demand for network bandwidth increases exponentially, although operators have improved the ability of the network to carry and transmit data through continuous expansion of physical bandwidth and related technologies, the increase in physical bandwidth always lags behind the user's requirements for data transmission. Under the impact of large data volume, how to ensure the reliability of the transmission of various services carried by the network and the quality of service (Quality of Service, QoS) of the corresponding services have been carried out, and a lot of research work has been carried out. At the same time, operators all hope to reduce costs and increase rev...
