摘要： In one embodiment, a particular field area router (FAR), in a local computer network (e.g., a mesh network) having a plurality of FARs, advertises a common subnet prefix assigned to the local computer network into a global computer network. Each of the plurality of FARs of the local computer network is configured to accept any traffic destined to the local computer network, and a tunnel overlay is built among the plurality of FARs. Upon receiving a packet at the particular FAR destined to a particular device in the local computer network, and in response to the particular FAR not having a host route to the particular device, it forwards the packet on the tunnel overlay to another of the plurality of FARs of the local computer network.

摘要： 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.
摘要翻译：在一个实施例中，数据聚合器发现（DAD）消息可以由相关联的数据聚合器分发，DAD消息标识发起数据聚合器，并且包括从数据聚合器到接收特定节点的记录路由以及总数特定节点通过记录的路由并经由数据聚合器到达DAG的根节点的路径开销。与特定节点通过DAG到达根节点的基于DAG的路径开销相比，接收特定节点基于总路径开销来确定与数据聚合器的使用相关联的路径成本增加（PCI）。如果PCI低于配置的阈值，则特定节点可以根据记录的路由将流量重定向为数据聚合器作为源路由业务。因此，流量可以由数据聚合器进行聚合。

摘要： In one embodiment, hidden neighbor relationships are identified based on received neighbor information from a plurality of nodes in a communication network. Based on determining a number of hidden neighbors for a particular node at various node parameters, a cost function associated with the particular node may be determined and utilized. In another embodiment, a number of hidden nodes of the particular node is determined across a range of transmission powers, and a delay associated with the particular node reaching a root node in the network across the range of transmission powers is also determined based on the neighbor nodes reachable at respective transmission powers. A tradeoff is determined across the range of transmission powers between the number of hidden nodes and the delay, and then the transmission power of the particular node can be set based on an acceptable determined tradeoff.

摘要： In one embodiment, a conference with multiple end points is provided. At the locations, multiple screens may be configured to display video from a portion of the multiple end points. Video from multiple locations is output onto the multiple screens, such as video streams from N different segments are output on N different screens. The video output may be determined based on a first dimension of the floor control algorithm. A push-to-talk input may then be received from a button. A video segment associated with the push-to-talk button is then determined and the video segment is output on one of the multiple screens in response to receiving the push-to-talk input. The push-to-talk input may be used by users that cannot actively participate in the first dimension of the floor control algorithm. For example, users using sign language cannot speak louder and thus by using the push to talk button or hand gestures can indicate their desire to be switched in as one of the displayed segments.

摘要： In one embodiment, a method includes establishing a first virtual talk group (VTG) that includes a plurality of endpoints and has a first multicast address. The plurality of endpoints includes a first endpoint and a second endpoint. The method also includes monitoring traffic associated with the first VTG, determining when a denial of service (DOS) attack is indicated by the traffic, and identifying at least one rogue endpoint responsible for the DOS attack when it is determined that the DOS attack is indicated. The first endpoint and the second endpoint are notified that they are to participate in a dynamic switchover to a second VTG when a DOS attack is indicated. The second VTG is established using a second multicast address, and includes the first endpoint and the second endpoint, but not the rogue endpoint.

摘要： 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.
