How Zoom Works: Low-Latency WebRTC & Video Mixing Clusters
Architectural analysis of Zoom: Selective Forwarding Unit (SFU) video routing, H.264 video compression, WebRTC audio/video streams, and global server cluster distribution.
Zoom's architecture is a real-time video conferencing engine engineered for low-latency, high-definition video calls even over poor network connections. It relies on Selective Forwarding Units (SFU), adaptive bitrate video encoding (H.264/SVC), and global edge server clusters.
Deep Technical Specifications & Benchmark Facts
Key Engineering Pillars
- Selective Forwarding Unit (SFU) media routing distributing video streams without heavy server-side decoding overhead
- Adaptive bitrate streaming adjusting video resolution dynamically based on network packet loss
- Sub-150ms global audio/video latency achieved through edge server cluster distribution
- End-to-end encryption (E2EE) protecting meeting streams using AES-256 GCM keys
