Explainer https://github.com/explainers-by-googlers/Multicast-in-Direct-Sockets Specification None Summary Allows Isolated Web Apps to subscribe to multicast groups and receive UDP packets from there, and to specify additional parameters when sending UDP packets to multicasts addresses. Blink component Blink>Network->Direct Sockets Motivation 1. Synchronous video stream from one device to the whole network of devices. For example, imagine in a shopping mall there would be multiple displays which show videos simultaneously on all devices. 2. Device discovery on a local network. mDNS protocol uses multicast sockets under the hood. In short, when a device joins a network, it sends a message: “Hello, I am headphones-10, my ip is '20.20.20.14' . Who else is here?”, other devices reply and in such a manner all devices can know about each other without a central server.
