  • Publication number: 20160182121
    Abstract: In one embodiment, a management device determines a topology of nodes in a network. Based on the topology, frequency hopping sequences are assigned (and notified) to the nodes such that each particular node of a certain set of the nodes is assigned a frequency hopping sequence on which to transmit that is different than frequency hopping sequences of neighbors and hidden neighbors of that particular node. In another embodiment, a transmitting node first transmits a transmission indication signal on its particular frequency band based on its frequency hopping sequence, and then transmits a message on the particular frequency band. In a further embodiment, a receiving node listening to a plurality of frequency bands may detect the transmission indication signal on the particular frequency band. In response, the receiving node filters out all frequency bands other than the particular frequency band, and receives the following transmission on that particular frequency band.

  • Patent number: 9356858
    Abstract: In one embodiment, a data aggregator discovery (DAD) message may be distributed by an associated data aggregator, the DAD message identifying the initiating data aggregator, and comprising a recorded route taken from the data aggregator to a receiving particular node as well as a total path cost for the particular node to reach a root node of the DAG through the recorded route and via the data aggregator. The receiving particular node determines a path cost increase (PCI) associated with use of the data aggregator based on the total path cost as compared to a DAG-based path cost for the particular node to reach the root node via the DAG. If the PCI is below a configured threshold, the particular node may redirect traffic to the data aggregator as source-routed traffic according to the recorded route. The traffic may then be aggregated by the data aggregator, accordingly.

  • Patent number: 9319852
    Abstract: A system and methodology to facilitate communication between non-compatible communication devices by utilization of a dynamic media proxy is provided. Information associated with an endpoint, such as, media capabilities, identity and system resource information is collected. Media proxy'ing is performed as part of capability negotiation. A dynamic media proxy is employed based on an analysis of the collected information. An analysis component can identify an endpoint that does not adhere to specific rules of transmission and can dynamically connect such an endpoint to a VTG (virtual talk group) via a proxy to prevent the endpoint from transmitting media into an active VTG that already has multiple talkers streaming media. Additionally, the location where media processing can occur can be dynamically determined based on the available system resources.

  • Patent number: 9306833
    Abstract: In one embodiment, a particular node in a computer network, that is, one receiving electrical power from a grid source, may determine routing metrics to a plurality of neighbor nodes of the particular node in the computer network. In addition, the node also determines power grid connectivity of the plurality of neighbor nodes. Traffic may be routed from the particular node to one or more select neighbor nodes having preferred routing metrics, until a power outage condition at the particular node is detected, at which time the traffic (e.g., last gasp messages) may be routed from the particular node to one or more select neighbor nodes having diverse power grid connectivity from the particular node. In this manner, traffic may be routed via a device that is not also experiencing the power outage condition.

  • Patent number: 9257117
    Abstract: Contact center agents often work in close proximity to other agents. As a primary agent is engaged in a call, a neighboring agent speech may be picked up by the primary agent's microphone. Contact centers using automated speech recognition systems may monitor the agent's speech for key terms and, if detected, respond accordingly. Determining a primary agent spoke a key term, when the true speaker of the key term is a neighboring agent, may cause errors or other problems. Characterizing at least the primary agent's voice and then, once a key term is detected, determining if it was the primary agent that spoke the key term, may help to reduce the errors. Additionally, computational requirements may be reduced as non-key terms may be quickly discarded and optionally, key terms determined to not have been spoke by the primary agent, may also be discarded without further processing.

  • Publication number: 20160019882
    Abstract: A contact center system can receive audio messages. The system can review audio messages by identifying phoneme strings within the audio messages associated with a characteristic. A phoneme can be a component of spoken language. Identified phoneme strings are used to analyze subsequent audio messages to determine the presence of the characteristic without requiring human analysis. Thus, the identification of phoneme strings then can be used to determine a characteristic of audio messages without transcribing the messages.

  • Patent number: 9210045
    Abstract: In one embodiment, a particular node in a computer network receives an indication of a number of child nodes of one or more potential parent nodes to the particular node in a primary directed acyclic graph (DAG). From this, the particular node selects a particular potential parent node with the highest number of child nodes as a secondary DAG parent for the particular node, and joins the secondary DAG at the selected secondary DAG parent (e.g., for multicast and/or broadcast message distribution). This may recursively continue, such that nodes gravitate toward parents with more children, potentially allowing parents with fewer children to relinquish their parental responsibilities.

  • Patent number: 9198203
    Abstract: According to one or more implementations of the disclosure, packets may be transmitted in a low power and lossy network (LLN) by receiving, on a first node, a message from a sending node, and by activating a critical message configuration to be applied in routing the message. A message identifier (e.g., signature) for the message may also be received or gleaned. The message identifier can be compared at the first node to a list of stored message identifiers, created based on routing history, to determine if the message has already been received. As such, if the message has not been received at the first node previously, a first parent and a second parent for the message are identified and the message, along with the critical message indication, can be transmitted to the first parent and the second parent, thereby achieving redundancy in the routing of the message.
