Automatic Bridging for Mobile Wireless Backhaul System

Backhaul networks, serving as the intermediary link from the front-end radio network to the central core network, play a crucial role in end-to-end communication by transporting significant traffic volumes. Apparently, packet transmission efficiency depends on their deployment scenarios; indeed, the more flexibility often translates to the better user experience for the end-user in critical situations. In this work, we propose an automatic bridging system for mobile wireless backhaul designed for high flexibility and compatibility. It features a fully automated establishment of wireless backhaul links, supported by a VXLAN-based packet transmission pipeline and an auto-binding mechanism. We prototype the system on Linux-based operating system with standard packages to ensure the compatibility operation and WiGig modules; the evaluation demonstrates that the VXLAN-based system can achieve lower latency, with a reduction ranging from 15% to 38% compared to the static forwarding-based system.
