20140355619 | INDUSTRIAL NETWORK APPARATUS AND DATA COMMUNICATION METHOD - An industrial network apparatus includes: a control data communicator configured to transmit control data in a priority transmission period that occurs periodically; and a message data communicator configured to determine whether or not to start transmission of message data in a non-priority transmission period depending on a required transmission time of message data and remaining time of the non-priority transmission period that is different from the priority transmission period, and to transmit the message data when determining to start transmission of the message data. | 2014-12-04 |
20140355620 | Method for Aiding the Reservation of Resources for a Packet Switched Network, and Associated Management Device and Aid Device - A method intended to aid in the reservation of resources within a packet-switched communication network (CR) comprising a number N of relaying nodes (S | 2014-12-04 |
20140355621 | CHANNEL ADAPTATION TO COMPENSATE FOR INTERFERENCE FROM NEIGHBOR POWERLINE COMMUNICATION NETWORKS - A first powerline communication device, associated with a first powerline communication network, determines a plurality of time intervals in a beacon period of the first powerline communication network based, at least in part, on variations in levels of interference from a second powerline communication network which shares a powerline communication medium with the first powerline communication network. The first powerline communication device determines at least one channel adaptation parameter for each of the plurality of time intervals in the beacon period to compensate for effects of the variations in the levels of interference from the second powerline communication network. The first powerline communication device applies the at least one channel adaptation parameter corresponding to one or more of the plurality of time intervals in the beacon period when transmitting data via the powerline communication medium. | 2014-12-04 |
20140355622 | COMMUNICATION SYSTEM - A communication system is provide which includes a plurality of communication units connected to a communication line, in which collisions occur between dominant signals outputted from the communication units on the communication line. At least one of the communication units includes a first driver which is set so that a variation of voltage applied to the communication line in transmission of the dominant signal with respect to that in absence of transmission of the dominant signal is smaller than a variation of voltage applied from another of the communication units to the communication line in transmission of the dominant signal. One of the communication units, which differs from the communication unit including the first driver, includes a second driver which limits variation per unit time of current flowing through the communication line in transmission of the dominant signal. | 2014-12-04 |
20140355623 | Transmission Control Protocol (TCP) Connection Control Parameter In-Band Signaling - Destination endpoints can use in-band signaling to adjust TCP parameters, to adjust entries in history and profile tables, to initialize a transition to an in-band communication mode, or to communicate short flows and/or alerts to a mobile device. A destination endpoint achieves in-band singling by embedding sequence number patterns in acknowledgement (ACK) messages, or by transmitting ACK messages (duplicates or otherwise) in accordance with an ACK sequence pattern. The sequence number or ACK sequence pattern can be pre-associated with any in-band communication message, such as a request to adjust TCP parameters, the reporting of a network or triggering condition, a request to adjust entries in a history or profile table, an indication to transition from a normal communication mode to an in-band communication mode, etc. | 2014-12-04 |
20140355624 | TRANSMITTING MULTIPLE ADAPTIVE BIT RATE (ABR) SEGMENT STREAMS ON A SHARED FREQUENCY - A system for transmitting multiple adaptive bit rate (ABR) segment streams on a shared frequency may include an ABR segment generator and transmitter circuitry. The ABR segment generator may encode a content item based at least in part on different ABR profiles to generate encoded streams. The ABR profiles may indicate encoding parameters corresponding to the encoded streams, e.g., bit rates, resolutions, frame rates and/or codecs. The ABR segment generator may be further configured to segment the encoded streams to generate ABR segment streams. The transmitter circuitry may be configured to transmit the ABR segment streams on a shared frequency, such as by transmitting the segment streams over spatially separated antennas, or by applying different orbital angular momentums to the ABR segment streams. In one or more implementations, the system may further include a segment interleaver that is configured to interleave the ABR segment streams. | 2014-12-04 |
