视频直播带宽计算器.
根据观众人数和码率阶梯，估算直播或点播视频的峰值带宽、每月流量和 CDN 费用。
CALCULATED IN YOUR BROWSER · NOTHING IS UPLOADED
One high-quality stream when the platform transcodes; the sum of all levels when you transcode locally.
Peak delivery bandwidth4.15 Gbps1,000 viewers
- Average bitrate per viewer
- 4,147 kbps
- Monthly data delivered
- 44.79 TB
- Upload needed at the encoder
- 9 Mbps 1.5 × the encoder output, a common safety margin
- Single-server 10 GbE capacity
- 1,929 viewers At 80 % of the port
- Live and on-demand video delivered from one origin rarely scales past a few thousand viewers; a CDN serves cached segments close to viewers.
- Bitrates are your encoding ladder; use the bitrates configured in your encoder or platform.

英语技术说明
Bitrates are your encoding settings; CDN prices are entered by you. Player buffering and retransmissions are covered only by the overhead percentage. Everything is calculated in your browser; nothing is sent or probed on the network.
Average bitrate is weighted by viewer share; peak bandwidth = peak viewers × average bitrate; monthly data = average viewers × bitrate × hours.
1,000 viewers on a 1080p/720p/480p/360p ladder need about 4.2 Gbps at peak.
