The Formula
Total Bandwidth (bps) = Viewers × Bitrate × Protocol Overhead
Protocol overhead: HLS/DASH ~5%, RTMP ~3%, SRT ~8%, WebRTC ~15%. The safety buffer accounts for peak traffic spikes and viewer growth.
Bandwidth Requirements by Event Size

| League Match | 50,000 | 4 Mbps | 200 Gbps |
| Championship | 500,000 | 6 Mbps | 3 Tbps |
| World Cup Final | 5,000,000 | 6 Mbps | 30 Tbps |
