Abstract: In example implementations, a method to create sub-groups of remote computing devices is provided. The method includes establishing, via a processor of a sending machine: a respective connection to a plurality of remote computing devices. The processor groups the plurality of remote computing devices into a plurality of sub-groups based on a common network. The processor identifies a remote computing device as a relay device within each one of the plurality of sub-groups having a best connection to the sending machine within a respective sub-group. Then a connection of remaining remote computing devices that are not identified as the relay device are redirected by the processor to the remote computing device that is identified as the relay device within the respective sub-group.
