    Abstract: In one embodiment, a client device determines when it is coupled to an IoT/LLN device to establish and enable an IP link between a headset interface on the client device and a signal interface on the IoT/LLN device. Once the IP link is established, a duplex data signal is transmitted between the client device and the IoT/LLN device, via the IP link.

    Abstract: In one embodiment, a device receives a destination unreachable message originated by a particular node along a first source route, the message carrying an encapsulated packet as received by the particular node. In response, the device may determine a failed link along the first source route based on a tunnel header and the particular node. Once determining an alternate source route without the failed link, the device may re-encapsulate and re-transmit the original packet on an alternate source route with a new tunnel header indicating the alternate source route (e.g., and a new hop limit count for the tunnel header and an adjusted hop limit count in the original packet).

    Abstract translation: 在一个实施例中，设备从第一源路由接收由特定节点发起的目的地不可达消息，该消息携带由特定节点接收的封装分组。 作为响应，设备可以基于隧道报头和特定节点来确定沿着第一源路由的故障链路。 一旦确定了没有故障链路的替代源路由，设备可以在备用源路由上重新封装并重新发送原始分组，其中新的隧道报头指示替代源路由（例如，并且新的跳数限制计数为 隧道报头和原始分组中的调整跳频限制计数）。

    Abstract: In one embodiment, a source node monitors a quality of a primary link, and forwards one or more duplicate copies of a packet in response to poor quality of the primary link. Specifically, forwarding generally comprises transmitting a first copy of the packet on the primary link with an indication of duplicate copies, and transmitting a second copy of the packet on a backup link with an indication of duplicate copies. In another embodiment, an intermediate node receives a first copy of a packet with an indication of duplicate copies, and stores an identifier of the first copy of the packet in response to the indication. Upon receiving a second copy of the packet with the indication of duplicate copies, the node determines whether the identifier of the second copy matches the stored identifier of the first copy, such that in response to a match, the second copy is dropped.

    Abstract translation: 在一个实施例中，源节点监视主链路的质量，并且响应于主链路质量差而转发分组的一个或多个重复副本。 具体地，转发通常包括在主链路上发送分组的第一副本，并具有重复副本的指示，以及在具有重复副本的指示的备份链路上发送该分组的第二副本。 在另一个实施例中，中间节点接收具有重复副本的指示的分组的第一副本，并且响应于该指示而存储分组的第一副本的标识符。 在接收到具有重复副本的指示的分组的第二副本时，节点确定第二副本的标识符是否与存储的第一副本的标识符相匹配，使得响应于匹配，第二副本被丢弃。

    Abstract: In one embodiment, data packet messages are received in a Field Area Router (FAR) sent from one or more sources toward one or more destination devices in a Low-Power Lossy Network (LLN). An LLN routing topology for the data packet messages is interpolated in the FAR. An expected time for the data packet messages to reach a destination device in the LLN is determined based upon the routing topology interpolation. Traffic shaping is applied by the FAR for the data packet messages based upon the determined expected time for the data packet messages to reach destination devices in the LLN.

    Abstract: In one embodiment, a device in a network detects a power outage event. The device monitors one or more operational properties of the device, in response to detecting the power outage event. The device determines whether to initiate a traffic control mechanism based on the one or more monitored operational properties of the device, according to a power outage traffic control policy. The device causes one or more nodes in the network that send traffic to the device to regulate the traffic sent to the device, in response to a determination that the traffic control mechanism should be initiated.
