Method and system for file deployment via dynamically assigned local relays

A computing device, comprising:

• a communications interface configured to establish a connection to a local area network;
• a memory storing configuration data;
• and
• a processor configured to:
• receive, via the communications interface, an update instruction from a device management subsystem external to the local area network;
• in response to receiving the update instruction,
• determine that the first client computing device satisfies a first wave condition defined in the configuration data where the first wave condition is based on an attribute of an identifier of the first client computing device, and
• obtain status data from a plurality of client computing devices connected to the local area network;
• based on the status data, determine whether to activate a controller operating mode at a first client computing device;
• in response to activating the controller operating mode, select one of the plurality of client computing devices to operate in a local relay operating mode;
• instruct the selected client computing device to activate the local relay operating mode, for causing the selected client computing device to obtain an update file from the device management subsystem and to deploy the update file to the client computing devices via the local area network.
