    摘要: In one embodiment, a node may determine a trigger for establishing transmission priority on a path through a shared-media communication network for priority traffic to a particular node. As such, the node may generate a path clear message (PCM) that would instruct one or more receiving nodes along the path to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of each respective receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration. After transmitting the PCM along the path to the particular node to establish the transmission priority for the priority traffic along the path through the shared-media network, the priority traffic may be transmitted to the particular node along the path during the transmission priority.

    摘要: 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.

    摘要: In one embodiment, a sender in a frequency hopping wireless network classifies a message as a large message to be fragmented into a plurality of packets for transmission to a receiver, and in response, indicates to the receiver that the message is a large message to request use of an orthogonal frequency hopping sequence between the sender and receiver for the duration of the large message transmission, the orthogonal frequency hopping sequence orthogonal to a shared frequency hopping sequence of the wireless network. Thereafter, the sender transmits the large message to the receiver on the orthogonal frequency hopping sequence, and returns to the shared frequency hopping sequence upon completion. In another embodiment, the receiver receives the indication that a message is a large message (requesting use of the orthogonal frequency hopping sequence). If the receiver can comply, the large message is received on the orthogonal frequency hopping sequence.

    摘要: In one embodiment, a node may determine a topology of a plurality of reporting nodes within a directed acyclic graph (DAG) in a computer network. The reporting nodes may then be assigned to one of a plurality of reporting groups, where reporting nodes are allowed to report only during designated time windows corresponding to their assigned reporting group. The reporting nodes may then be informed of at least their own assignment to a particular reporting group. In another embodiment, a particular reporting node may join the DAG, and may also receive an assignment to one of a plurality of reporting groups. Accordingly, the particular reporting node may also determine designated time windows corresponding to the assigned reporting group, where the particular reporting node is allowed to report only during the designated time windows.

In another embodiment, a node listens on a first frequency for a wireless CSDA signal regarding a second (colliding) frequency, and in response to receiving a CSDA signal, may refrain from transmitting a wireless signal on the second frequency for the particular duration, or else (if not receiving a CSDA signal), may allow transmission of a wireless signal on the second frequency, accordingly.

    摘要: 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.

    摘要: In one embodiment, a node may request to join a parent node in a directed acyclic graph (DAG) in a computer network, and may notify the parent node of a load associated with the request, and whether the node has any other parent node options. The response received from the parent node may be either an acceptance or a denial (based on the load and other parent node options), where in the case of an acceptance, the node may join the parent node in the DAG. Alternatively, in response to a denial, in one embodiment, the node may perform load shedding to become acceptable to the parent node. In another embodiment, a node receiving a join request from a child node may determine an impact associated with allowing the child node (and its load) to join the receiving node in the DAG prior to returning an acceptance or denial, accordingly.

    摘要: In one embodiment, a router maintains a communication session between a local terminal unit and a remote terminal unit, the local terminal unit interconnected to the router over a local serial data link, and the remote terminal unit interconnected to the router over an Internet Protocol (IP) session via a remote router and a corresponding remote serial data link. The router may then monitor a state of the local serial data link, and communicates this state with the remote router over the IP session, as well as a remote state of the remote serial data link. The router may then correspondingly control the state of the local serial data link to match the remote state of the remote serial data link.

    摘要: In one embodiment, a receiving node in a computer network may detect congestion, and also identifies a set (e.g., subset) of its neighbor nodes. In response to the congestion, the receiving node may assign a transmission timeslot to each neighbor node of the set based on the congestion, where each neighbor is allowed to transmit (synchronously) only during its respective timeslot. The assigned timeslots may then be transmitted to the set of neighbor nodes. In another embodiment, a transmitting node (e.g., a neighbor node of the receiving node) may receive a scheduling packet from the receiving node. Accordingly, the transmitting node may determine its assigned transmission timeslot during which the transmitting node is allowed to transmit. As such, the transmitting node may then transmit packets only during the assigned timeslot (e.g., for a given time). In this manner, congestion at the receiving node may be reduced.
