Abstract: A method for transmitting data from within a wired communication system is disclosed. A first network-enabled device can select one of a plurality of communication mediums for transmitting the data stream to the second device and transmit the data stream to the second device using the selected communication medium. The first device determines that the transmission of the data stream using the selected communication medium is being interfered with by transmission of other data from the first device to a third device on another of the plurality of communication mediums. In response to determining that the transmission of the data stream to the second device on the selected communication medium is being interfered with by the transmission of the other data to the third device using the other communication medium, the first device turns off the transmission of the other data to the third device on the other communication medium.

Abstract: Protocol data units (PDUs) associated with a packet stream are transmitted with sequence numbers to support reordering and selective acknowledgement. A selective acknowledgement (SACK) message may be used to indicate at least one sequence number of a lost or corrupted PDU which was not properly received by the receiving device. Responsive to the SACK message, the lost or corrupted PDU is retransmitted via a different path of the network, different from the path used to transmit the original PDU. Lost or corrupted PDUs may not be retransmitted if the estimated retransmission delay is greater than a delay tolerance associated with the quality of service requirements of the application. Instead, a control message (i.e. “cut losses” message) may be transmitted to indicate that PDUs earlier than a particular sequence number will not be transmitted.

Abstract: A device may determine adapted physical layer transmission properties based upon characteristics of a packet stream to be transmitted via a communications channel. The physical layer transmission properties may comprise an adapted tone map that is associated with an aggressive physical layer throughput capability for UDP traffic, a conservative physical layer throughput capability for TCP traffic, or a dynamically adjusted physical layer throughput rate for mixed traffic. An indication regarding the adapted tone map may be included in a first message, a portion of a physical layer framing protocol, a physical layer control transmission (such as a frame control symbol), or other transmissions such that the receiving device can derive the adapted tone map without significant added overhead.
