WebRTC - A tale of Beekeeping
summary
Demonstrates concrete builds: Hibuddy (simple 1:1 getUserMedia + RTCPeerConnection video), Bananaphone (group audio over full‑mesh with star/supernode tradeoffs), and Waggle.js (p2p chunked video streaming that reduces server bandwidth). Covers signaling choices, data channels, electing supernodes, a sliding window of chunks, and a timeout strategy that requests chunk fallback to the server when peers are slow. Shows what actually got built, the performance tradeoffs, and which mitigations make the system work in practice.
