Abstract

A computer-implemented method for collaborative caching of files during a collaboration session includes receiving a request from a first electronic device for a first file. The method determines whether the first file is stored in one or more caches, wherein the one or more caches are associated with one or more electronic devices. Responsive to determining the first file is stored in a cache of a second electronic device, the method determines whether the first file stored in the cache of the second electronic device meets a set of guidelines. Responsive to determining the first file stored in the cache of the second electronic device meets the set of guidelines, the method sends the first file from the cache of the second electronic device via an internal network to the first electronic device.
