Proactive Congestion Control by Fast Optical Switching Within 1-ms Delay at Mobile Backhaul Utilizing Traffic Data Volume

Abstract

The development and introduction of real-time remote control of robots using mobile NWs is expected. To realize this control, a network configuration in which the User Plane Function (UPF) and Mobile Edge Computing (MEC) are located near the Central Unit (CU) is considered. If traffic exceeds the processing capability of the UPF, there is the concern of congestion. In this paper, we propose and demonstrate a method for obtaining the uplink traffic volume from the CU and predicting the future traffic to switch the optical path and UPF before congestion occurs within the Mobile Backhaul (MBH) delay of 1ms.
