The present invention is directed to providing a system and method for using pre-established sub-networks within a larger network to improve the efficiency of transmitting media. Specifically, the current invention eliminates the need to re transmit a particular medium from its source to a sub-network. In using pre-established sub-networks, the present invention avoids the capital outlay that would be necessary to set up an infrastructure for new sub-networks.
