Publisher-subscriber architecture for video conferencing

A computer-implemented method, comprising:

• determining a plurality of client devices to participate in a conferencing session;
• determining a plurality of edge computing resources corresponding to the plurality of client devices;
• determining a plurality of publishing client devices from the plurality of client devices;
• determining, based at least in part on the plurality of publishing client devices, a plurality of publishing edge computing resources from the plurality of edge computing resources;
• determining a plurality of subscribing client devices from the plurality of client devices;
• determining, based at least in part on the plurality of subscribing client devices, a plurality of subscribing edge computing resources from the plurality of edge computing resources;
• publishing a plurality of data streams obtained from the plurality of publishing client devices at the plurality of publishing edge computing resources;
• pushing, via a data network, the plurality of data streams from the plurality of publishing edge computing resources to the plurality of subscribing edge computing resources;
• accessing the plurality of data streams from the plurality of subscribing edge computing resources;
• and
• presenting at least a portion of the plurality of data streams on at least the plurality of subscribing client devices to create a conferencing session for the plurality of client devices.

A computing system, comprising:

• one or more processors;
• and
• a memory storing program instructions that, when executed by the one or more processors, cause the one or more processors to at least:
• enable a conferencing session between a plurality of participating client devices, wherein enabling the conferencing session includes:
• obtaining, at a first plurality of edge computing resources associated with a plurality of publishing client devices, a plurality of published, individually addressable video streams, wherein the plurality of publishing client devices includes at least some of the plurality of participating client devices;
• pushing the plurality of individually addressable video streams from the first plurality of edge computing resources to a second plurality of edge computing resources associated with a plurality of subscribing client devices, wherein the plurality of subscribing client devices includes at least some of the plurality of participating client devices;
• fetching, by the plurality of subscribing client devices, the plurality of individually addressable video streams from the second plurality of edge computing resources;
• and
• presenting at least a portion of the plurality of individually addressable video streams on at least the plurality of subscribing client devices to create the conferencing session for the plurality of participating client devices.
