Google patents low-latency peer-to-peer network for live media

Patent drawing
Patent drawing from the official filing.

Google describes a method where a server organizes devices into a peer-to-peer network to share live media data. The server creates a specific configuration that maps out routes for the data to travel between devices, designating some as parents and others as children. This setup allows devices to forward live media to each other immediately upon receipt, reducing the need for a central server to handle all traffic.

Why it mattersThis could help reduce lag and bandwidth costs for live video streaming by letting devices share data directly with nearby peers.

In the filing’s own words

A method includes receiving, at a server, first requests to register with a first peer-to-peer network from a first node, a second node, and a third node, the first peer-to-peer network providing transmission of live media data. The method further includes generating a first configuration for the first peer-to-peer network comprising at least the first node, the second node, and the third node, the first configuration defining a first set of one or more media data routes to provide the live media data to one or more peer nodes of the first peer-to-peer network upon receipt of the live media data by a respective one of the first node, the second node, and the third node. The method further includes transmitting one or more portions of the first configuration to each of the first node, the second node, and the third node.

What exactly they claim (claim 1)

1. A method comprising: receiving, at a server, first requests to register with a first peer-to-peer network from a first node, a second node, and a third node, the first peer-to-peer network providing transmission of live media data; generating, at the server, a first configuration for the first peer-to-peer network comprising at least the first node, the second node, and the third node, wherein: the first configuration defines a first set of media data routes among the first node, the second node, and the third node prior to receipt of the live media data; the first configuration causes the first node, the second node, and the third node to forward the live media data based on the first set of media data routes upon receipt of the live media data by a respective one of the first node, the second node, or the third node; and the first configuration designates one or more of the first node, the second node, and the third node as child nodes of one or more other nodes to receive the live media data from a respective parent node of the one or more other nodes; and transmitting one or more portions of the first configuration to each of the first node, the second node, and the third node to cause the first node, the second node, and the third node to transfer the live media data according to the first set of media data routes.
