Physical-Layer Informed Multipath Redundancy Optimization for Mobile Real-Time Communication

Abstract

• Popular RTC applications pose strict requirements on end-to-end latency • E.g., cloud video gaming, video conferencing, remote surgery ... • High variations of mobile “last mile” greatly impact the path condition • A common solution: Send data redundantly on multiple paths • E.g., when the condition of a path worsens, • Congestion control, AQM ... × • Duplicate data on another path (in good condition) √ Background APNet 2021 – 5th Asia-Pacific Workshop on Networking.
