Abstract

In a packet network, message packets (130) are comprised of vacant or unused bits for future system enhancements or for remedying unknown design oversights or utilizing vacant portions of fixed length data packets.
Furthermore, message packets (130) comprise a message type identifier distinguishing message architecture. A
transmit and receive packet network node (100) maintains an unused bit catalog (125) listing vacant or unused bits of particular message packet types. When a message packet type having vacant or unused bits is detected propagating through the packet network, background data is retrieved from a transmit background data queue (115) and interleaved into such message packets to form enriched message packets (130') for transportation through the packet network. Receiving packet network nodes (100) detect enriched message packets (130') and extract and buffer the background data. A lower data-rate background data transfer mechanism is maintained without impacting the performance of the existing packet network.
