    Abstract: Methods of operating in a network in which a plurality of stations communicate over a shared medium and contend for access during a priority resolution period. At least some of the stations use a first CSMA network protocol having certain characteristics (e.g., some transmissions have a format that includes a start of frame delimiter (SOF), a payload, and an end of frame delimiter (EOF), wherein the SOF and EOF each contain sufficient information to permit a station receiving only one of the SOF and EOF to determine the start of a priority resolution period). And at least some stations use a second network protocol capable of coexisting with the first protocol, so that stations may communicate using either the first or second protocol. The second protocol may have various characteristics configured to achieve coexistence with the first protocol (e.g., transmissions that have a format that includes an SOF but not an EOF).

    Abstract: Communicating between stations over a shared medium comprises: receiving a first waveform at a first station transmitted over the shared medium from a second station, the first waveform including a payload having multiple segments, and during reception of a first segment of the payload, initiating processing of one or more segments of the payload received before the first segment of the payload to generate acknowledgement information that specifies which of one or more segments of the payload including the one or more processed segments have been correctly decoded by the first station; transmitting a second waveform from the first station over the shared medium, the second waveform including the acknowledgement information; and transmitting a third waveform from the first station over the shared medium, after transmitting the second waveform, the third waveform including acknowledgement information that specifies which of one or more segments of the payload including the first segment of the payload have been correctly decoded by the first station.

    Abstract: Network devices of a particular device class can implement a distributed bandwidth control (DBC) protocol to utilize resources of a communication network in accordance with a threshold amount of resources allocated for DBC device communication. A DBC device of a plurality of DBC devices can determine a transmission cost associated with a pending transmission and a total transmission cost associated with previous transmissions within a predetermined time interval associated with the plurality of DBC devices. If a sum of the transmission cost associated with the pending transmission and the total transmission cost associated with the one or more previous transmissions does not exceed a threshold transmission cost allocated for DBC device communication, the DBC device can initiate the pending transmission. Otherwise, the DBC device can delay the pending transmission.

    Abstract: Functionality for secure client authentication and service authorization in a shared communication network are disclosed. A managing network device of a communication network causes a securely connected client network device to perform an account authorization process with an accounting network device in parallel with a service matching process with the managing network device and one or more service providers of the communication network. The managing network device executes the service matching process and securely matches the client network device with one of the service providers. The accounting network device executes the account authorizing process with the client network device and provides a service voucher to the managing network device authorizing one or more of the service providers to service the client network device. The managing network device transmits the service voucher to the matched service provider to prompt the matched service provider to service the client network device.

    Abstract: Power save proxy functionality can be implemented to enable power save devices to switch to a power save mode and still receive communications from legacy communication devices. A first communication device determines that a second communication device is in a power save mode. The first communication device designates itself as a power save proxy for the second communication device that is in the power save mode. In response to detecting packets that are transmitted from a legacy communication device to the second communication device, the first communication device transmits a control message to the second communication device to request the second communication device to exit the power save mode, transmits a hold control message to the legacy communication device to request the legacy communication device to temporarily stop transmitting packets to the second communication device, or stores the packets intended for the second communication device.

    Abstract: A powerline communication (PLC) network can be subject to noise/interference resulting in loss of throughput and data corruption for PLC devices connected to the PLC network. A powerline interference analyzer can be implemented in the PLC network for detecting sources of the noise. The powerline interference analyzer can determine powerline network noise characteristics that are representative of noise on the PLC network and can analyze the powerline network noise characteristics to determine one or more noise patterns. The noise patterns can be compared with a plurality of predefined noise signatures that are representative of corresponding each of a plurality of noise sources. Consequently, at least one noise source that is associated with the noise patterns can be identified from the plurality of the noise sources.

    Abstract: Communicating among stations in a network includes providing repeated beacon transmissions from at least some of the stations including a first station. The first station is assigned to a first level. Any stations that can reliably receive transmissions from the first station are assigned to a second level. Any stations not assigned to any of the preceding levels that can reliably receive transmissions from the preceding level are assigned to each of one or more higher levels. Timing information at each station in a given level is synchronized according to transmissions received from at least one station in the preceding level.
