An API that allows web applications to join a multicast (S,G) and receive authenticated, congestion-safe multicast IP traffic from services that offer it.
It provides:
- per-packet authentication
- an origin-based security model
- protection against over-subscription
This lets browsers join in subscribing to popular live media events or file downloads (software or pre-recorded media) that make use of multicast IP to enable the efficient use of network and server resources.
See the explainer for more info.
Visit the demo page with a browser that implements the API to experiment with trying to receive traffic. (You may need some extra steps to receive external traffic, see the getting started primer for help, and please open issues if you encounter trouble.)
