  • Publication number: 20140119386
    Abstract: The present disclosure relates to a communication system which, in accordance with one exemplary embodiment, a communication network for providing network services to at least one network device and at least one distribution point (DP) coupled to at least one network backbone. The at least one network device is located remote from the DP and coupled to the at least one network backbone via the at least one DP. The at least one DP is configured to receive a plurality of data units from the at least one network backbone in accordance with one or more communication protocols. A plurality of data frames, each having a header portion and a payload portion, are generated and each one of the received data units are mapped into one or more payload portions of the plurality of data frames. One or more of the plurality of data frames are mapped to a payload portion of at least one data transfer unit (DTU), which is then communicated to the at least one network device.

  • Publication number: 20140071997
    Abstract: Described herein are techniques related to data communications using a data packet having at least one frame with a robust preamble for use over media having a high degree of non-stationary noise (e.g., impulsive noise). The described techniques employ a preamble with a structure having multiple transitions between the preamble sections. Each transition indicates the start of the upcoming frame. With the techniques described herein, if noise damages the transitions between such sections beyond recognition, the receiver can still determine the frame start time from the one or more of the undamaged transitions. Thus, the robustness of communications via the noisy media is significantly increased. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    Abstract: Representative implementations of devices and techniques provide communication between networked nodes operating on a communication network medium. In an implementation, a node generates a broadcast frame that includes at least a preamble and a payload. The preamble of the broadcast frame may include supplemental information. The supplemental information may be associated with one or more symbols of the preamble. The supplemental information may contain predetermined header information for use by nodes operating on the communication network medium.

  • Publication number: 20130283109
    Abstract: One embodiment relates to a device. The device includes reception circuitry adapted to receive a data unit from a first node of a network and a confirmation message signal from a second node of the network. Analysis circuitry is adapted to determine a failure to correctly receive the data unit. Transmission circuitry is adapted to transmit a negative acknowledgement signal to the first node in case the analysis circuitry determines the data unit has not been correctly received and the confirmation message signal from the second node is received. Other methods and devices are also disclosed.

  • Patent number: 8547990
    Abstract: One embodiment of the present invention relates to a network element that is configured to be associated with a network having a number of nodes. A proxy node is configured to distinguish between a some signals received from a master node and other signals received from at least one hidden node, where the at least one hidden node is unable to bi-directionally directly communicate with the master at a given time. The proxy node is further configured to relay at least one signal between the master node and the hidden node to facilitate addition of the hidden node to the network via the master node. Other methods and devices are also disclosed.

  • Patent number: 8493855
    Abstract: One embodiment relates to a method for communicating over a transmission medium shared between a plurality of nodes including a source node, a proxy node, and other nodes. In the method, a transmission data unit is transmitted from the source node to the proxy node and to the other nodes. A confirmation is selectively transmitted from the proxy node to the other nodes based on whether a reception data unit corresponding to the transmission data unit is correctly received at the proxy node. Based on whether the confirmation is received at one of the other nodes, a negative acknowledgement is selectively transmitted from the one of the other nodes to the source node. Other methods and devices are also disclosed.
