TL;DR: WebRTC promised sub-second streaming, but scalability was always the concern. In 2026, CDN-mediated WebRTC architectures have solved this. This technical analysis examines WebRTC's maturity for sports broadcasting at scale, addresses the 1,000-concurrent-per-domain limit, and shows how Tencent Cloud CSS's Fast Live architecture delivers WebRTC at millions of concurrent viewers.

WebRTC's Evolution: From P2P to CDN-Scale

2020: WebRTC = peer-to-peer, limited to hundreds of viewers
2023: WebRTC + SFU = thousands of viewers, still challenging
2026: WebRTC + CDN = millions of viewers, production-ready

Tencent Cloud CSS's Fast Live uses CDN-mediated WebRTC: the stream is ingested normally (RTMP), converted to WebRTC at the CDN edge, and delivered to viewers' browsers natively.

Addressing the 1,000 Concurrent Limit

CSS allows 1,000 concurrent WebRTC connections per push domain. For larger scale:

  • Use multiple push domains behind a load balancer
  • CSS automatically distributes viewers across edge nodes
  • Proven at millions of concurrent for major events
