Congestion Control for Future Mobile Networks.

The complexity and volatility of emerging mobile networks, which are intended to support extremely demanding applications such as high-resolution live video and AR/VR, pose immense challenges for congestion control. We present MORC, a novel rate-control protocol for mobile networks. MORC builds on the PCC protocol design framework to strike a balance between low latency and high throughput. Lab trials and early field tests show that MORC outperforms traditional TCP congestion control and the recent BBR protocol, achieving faster file download times, higher resiliency to network changes, better bandwidth utilization, and improved quality of experience for video clients. We discuss deployment scenarios and future research.
