Why WebRTC Chooses UDP Over TCP and How RTP/RTCP Keep Streams Smooth

This article explains why real‑time audio/video communication prefers UDP over TCP, compares TCP and UDP characteristics, introduces the RTP and RTCP application‑layer protocols that enable reliable media transport, and provides a quick Wireshark guide for capturing and analyzing RTP/RTCP packets.

Design and Implementation of Low‑Latency Real‑Time Streaming Protocols: RTP, RTCP, and Packet‑Loss Solutions

The article explains why TCP‑based protocols cannot meet low‑latency requirements for live‑streaming conferences and introduces RTP, RTCP, jitter, round‑trip time, and three packet‑loss mitigation strategies—retransmission, forward error correction, and cross‑transport—along with a brief overview of DCCP for congestion control.
