Network Architecture and Protocol Design of Multi-Path TCP with Multiple Cellular Networks on High-Speed Trains

초록

Due to the high mobility of high-speed trains, channel conditions can fluctuate rapidly and frequent cell-to-cell handovers can significantly reduce throughput. MPTCP (Multi-Path TCP) communication using a multi-cellular operator network can address the problems encountered in the high-speed train environment because it can utilize at least one path that is immune to handovers at any given time. As a result, research and development efforts are underway in various countries to leverage multi-cellular networks to provide high-speed Internet services to high-speed train passengers. By utilizing MPTCP technology, it becomes possible to aggregate the bandwidth of multiple cellular networks to provide faster and more reliable Internet services to high-speed train passengers. In this study, we investigate two approaches, load balancer and MPTCP, to provide enhanced Internet services on high-speed trains using multiple cellular networks. We also propose a network architecture and signaling procedure for applying MPTCP on high-speed trains. Furthermore, we discuss related issues and our future work. © 2024 IEEE.
