The HOP Protocol: Reliable Latency-Bounded End-to-End Multipath Communication

Next-generation wireless networks are expected to enable new applications with strict latency constraints. However, existing transport layer protocols unable meet the stringent Quality of Service (QoS) requirements on throughput and maximum latency: excessive queuing due capacity-oriented congestion control inflates end-to-end well beyond interactivity deadlines. In this work, we propose a novel framework that evolves best-effort communications into reliability- latency-aware for QoS-sensitive applications. The protocol, named High-reliability latency-bounded Overlay Protocol (HOP), provides combination packet-level Forward Error Correction (FEC) multipath scheduling compensate capacity drops pre-defined QoS requirements. More specifically, sender splits data associated redundancy between paths by using stochastic forecast their future decides amount necessary application’s without clogging connections. We compare HOP’s performance state-of-the-art in ns-3 simulations both synthetic live network traces, confirm our scheme can reliably deliver high-throughput data, reducing number late blocks 2 5 times respect optimized Multipath TCP (MPTCP).
