Abstract:
A network device may include a plug that couples with a socket to couple the network device to a PLC network. A position of the plug may be interchanged when the plug is coupled with the socket. In one example, the network device may determine a coupling orientation of the plug that indicates the position of the plug with respect to the socket. The plug includes a first plug terminal, a second plug terminal, a first ground plug terminal, and a second ground plug terminal. The network device may select a signal polarity for the plug based, at least in part, on the coupling orientation. The signal polarity indicates over which of the plug terminals data is to be transmitted for communication over the PLC network.
Abstract:
A first client may establish a power charging association with one of a plurality of service agents over a network. The first client transmits a first signal via a first attachment point of a powerline network, the first signal associated with requesting the power charging association. The first client broadcasts a sounding message via the first attachment point after transmitting the first signal, wherein the sounding message is receivable by one or more service agents including at least a first service agent of the powerline network. The first service agent received the sounding message with a lowest attenuation of the one or more service agents that received the sounding message. The power charging association is established between the first client and the first service agent.
Abstract:
A network device can be configured to dynamically adapt its current primary receiver coupling to channel conditions. For each of a plurality of transmitting network devices, the network device can determine a potential primary receiver coupling of the first network device for receiving communications from the transmitting network device based, at least in part, on a performance measurement associated with each of the plurality of communication channels between the network device and the transmitting device. The network device can select its current primary receiver coupling based, at least in part, on the potential primary receiver couplings determined for the plurality of transmitting network devices. In addition, the network device can also determine how to communicate with a receiving network device based, at least in part, on a preferred communication channel between the two network devices and a current primary receiver coupling of the receiving network device.

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:
A network device may be configured to iteratively modify an initial tone map for each communication region of a powerline cycle to minimize the time before application data can be transmitted. A first network device estimates an initial tone map for each communication region based, at least in part, on sounding messages received from a second network device. The first network device determines whether to estimate a modified tone map for the first communication region based on at least one performance measurement associated with a data packet generated using the initial tone map for the first communication region. If so, the second network device retransmits the sounding messages in the first communication region that will be used to modify the initial tone map for the first communication region, and the second network device continues to transmit the data packets using the initial tone maps in the remaining communication regions.
Abstract:
Communicating among stations in a network includes, from each of multiple stations in the network, transmitting information indicating which other stations from which that station is able to reliably receive transmissions. A schedule for communicating among the stations is determined based on the information from the stations and transmitting the schedule over the network. The schedule includes a plurality of time slots during which respective contention groups of stations are assigned to communicate using a contention-based protocol.

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.
