Transmission method and system for concurrently binding and bearing large data volume services based on plurality of data channels

Abstract

The invention belongs to the field of network transmission communication, relates to a transmission method for concurrently binding and bearing large data volume services based on a plurality of datachannels. The method comprises a sending process from an application layer to a transmission layer, and is characterized in that the sending process comprises the following steps: 1) receiving a maindata packet from the application layer, performing packet cutting processing and redundancy processing on the main data packet to form sub-data packets, and summarizing the sub-data packets to finallyform a sub-data packet pool; 2) respectively evaluating the transmission capacity of each data channel, and scheduling all the data channels according to the transmission capacity of the data channels; and 3) according to a transmission protocol between the application layer and the transmission layer, calling the sub-data packets from the sub-data packet pool obtained in the step 1), and transmitting the sub-data packets in the data channel. According to the method, the network resource bandwidth can be fully utilized, the transmission delay and jitter are reduced, the transmission stabilityand fluency are improved, and the method has more convenient, safer, more stable and smoother transmission experience in network communication.

Description

technical field [0001] The invention belongs to the field of network transmission and communication, and relates to a transmission method and system for carrying large data volume services, in particular to a transmission method and system for carrying large data volume services based on concurrent bundling of multiple data channels. Background technique [0002] In recent years, with the rapid development of access technology, many terminals have multiple communication interfaces, the coverage of heterogeneous networks is increasing, and the selectivity of communication interfaces is improved. Internet traffic has shown explosive growth, and more and more services have shown a huge demand for high bandwidth, such as high-definition video streaming services (big data volume services). Under such circumstances, the traditional single-path transmission method may not be able to meet the high bandwidth requirements of the business, and cannot take advantage of the advantages of...

AI Technical Summary

Problems solved by technology

[0004] At present, there are still many problems in the concurrent bundled transmission of multiple data channels, mainly related to problems such as low transmission throughput caused by path differences, unreasonable bandwidth utilization, and large uncertainty in path parameter sampling and collection. These problems lead to At present, multi-path transmission cannot efficiently utilize network resources, effectively reduce transmission delay and jitter, and even fail to reach the performance level of single data channel transmission in some cases
