High-speed uploading architecture using distributed edge servers on multi-RAT heterogeneous networks

Uploading of huge files to cloud servers through mobile communication has been becoming more popular in recent years. However, current uploading throughput is frequently limited due to bottlenecks in server processing ability and/or narrow bandwidth sections of networks. For this study, we aimed to improve the user experience of uploading in future wireless access environments. We propose a novel upload cache architecture that flexibly uses computer resources located on the network edge and achieves high-speed uploading with parallel uploading of divided files. We also report on the evaluation results of throughput improvement (more than 10 times faster) by implementing our proposed architecture to prototype software.
