How AutoRec Cuts Live‑Streaming Stalls by Over 11% with Smarter Packet Recovery

The paper “Toward Timeliness‑Enhanced Loss Recovery for Large‑Scale Live Streaming” introduces AutoRec, an on‑off‑mode‑aware packet‑loss recovery mechanism implemented on QUIC that reduces average stall frequency by 11.4% and duration by 5.2% without client‑side changes, and validates its effectiveness in both test‑bed and real‑world CDN deployments.

Fundamentals of TCP: Role, Packet Size, Sequencing, Assembly, Slow Start, and Loss Recovery

This article explains the basic principles of the TCP protocol, covering its purpose in ensuring reliable data transmission, packet size limits, sequence numbering, how packets are reassembled by the operating system, the slow‑start mechanism with ACK handling, and methods for detecting and retransmitting lost packets.
