摘要： A trust management system is provided for a network communication ecosystem having a plurality of participating entities. The trust management system includes a trust specification engine configured to define and manage trust relationships between a first entity and a second entity of the plurality of participating entities, a trust analysis engine configured to process the results of a trust query from the first entity to the second entity, a trust evaluation engine configured to evaluate the trust relationships managed by the trust specification engine, and a trust monitor configured to (i) monitor one or more trust triggers occurring relevant to at least one of the first and second entities, and (2) update a trust relationship between the first and second entities based on one or more monitored trust triggers.

摘要： A digital receiver is configured to process a polarization multiplexed carrier from a communication network. The polarization multiplexed carrier includes a first polarization and a second polarization. The receiver includes a first lane for transporting a first input signal of the first polarization, a second lane for transporting a second input signal of the second polarization, a dynamic phase noise estimation unit disposed within the first lane and configured to determine a phase noise estimate of the first input signal, a first carrier phase recovery portion configured to remove carrier phase noise from the first polarization based on a combination of the first input signal and a function of the determined phase noise estimate, and a second carrier phase recovery portion configured to remove carrier phase noise from the second polarization based on a combination of the second input signal and the function of the determined phase noise estimate.

摘要： A system and method for data collection and aggregation using a distributed network of communications enabled sensors connected to another primary network to achieve a secondary out-of-band monitoring perspective, for example, in power grids. The data collection system includes an aggregation and processing server configured to collect data from a variety of sensors adjacent to the monitored network each sensor includes secondary power such that it can continue data transmission even during power grid outages. The data collection system includes a method for secure real-time data ingest, machine learning enabled analysis, risk assessment, and anomaly detection on a broad geographic scale irrespective of isolated network boundaries.

摘要： A notification server is provided for a multi-network wireless communication system. The notification server includes a processor and a memory having computer executable instructions stored therein. The instructions, when executed by the processor, cause the processor to receive first device information from a mobile communication device wirelessly connected to a macro cell network of the multi-network wireless communication system. The instructions further cause the processor to determine, based on the received first device information, that a small cell network of the multi-network wireless communication system is available for communication with the mobile communication device. The instructions further cause the processor to transmit a notification to the mobile communication device to search for the small cell network for transition thereto.

摘要： Systems and methods presented herein provide for improving communications when encountering aggressive communication systems. In one embodiment, a communication system comprises a wireless access point operable to link a first user equipment (UE) to a WiFi network via a contention based mode that directs the WAP to share radio frequency spectrum with other WAPs. The communication system also comprises a communication processor operable to query at least the first UE to determine aggressive radio frequency (RF) band activity by another communication system in range of the WAP, to determine that the aggressive RF band activity by the other communication system is pushing communication with the first UE via the WAP below a threshold level, and based on the determination, direct the WAP to switch to a contention free mode to communicate with the first UE in contention free mode.

摘要： Predictive management of a network buffer is contemplated. The network buffer maybe predictively managed to control packet drop based at least in part on predicted sojourn time. The predicted sojourn time may be determined to predict time needed from an arriving packet to travel through a queue of the network buffer.

摘要： Facilitating echo cancellation within communication networks is contemplated, such as but not necessarily limited to facilitating echo cancellation within full-duplex (FDX) communication networks. The echo cancellation may optionally be performed with an echo canceller included as part of or otherwise associated with an FDX node used to facilitate interfacing signaling between a digital domain and an analog domain of a FDX or other communication network.

摘要： An optical access network includes an optical hub having at least one processor. The network further includes a plurality of optical distribution centers connected to the optical hub by a plurality of optical fiber segments, respectively, and a plurality of geographic fiber node serving areas. Each fiber node serving area of the plurality of fiber node serving areas includes at least one optical distribution center of the plurality of optical distribution centers. The network further includes a plurality of endpoints. Each endpoint of the plurality of endpoints is in operable communication with at least one optical distribution center. The network further includes a point-to-point network provisioning system configured to (i) evaluate each potential communication path over the plurality of optical fiber segments between a first endpoint and a second endpoint, and (ii) select an optimum fiber path based on predetermined path selection criteria.

摘要： The present disclosure generally relates to systems, methods and software for determining an optimal burst transmission time through a modem, such as a cable modem, a wireless access point, a node in a cable network, or a satellite communication link. Particularly, the present disclosure makes it possible for a burst of queued data, defined as data above a certain percentile of a monitored traffic rate, to be transmitted by the modem at a time that provides the best chance of avoiding a collision with a co-occurring burst of data from another user connected to the same modem. In an embodiment, the systems, methods and software disclosed herein use the optimal transmission time to replace a contention window transmission time, at least for bursty data, or they completely eliminate the need for contention windows, at least for bursty data.
