摘要： In one embodiment, a sensor device in a network detects an alarm condition. The sensor device generates an alarm message based on the detected alarm condition and waits for a delay whose length is inversely proportional to a distance between the sensor device and a downstream destination device for which the alarm message is destined. During the delay, the sensor device receives one or more additional alarm messages from one or more upstream sensor devices. The sensor device coalesces the one or more received alarm messages from the one or more upstream sensor devices with the alarm message generated at the sensor device, to form a coalesced alarm message, and transmits the coalesced alarm message downstream towards the downstream destination device, after expiration of the delay.

摘要： In one embodiment, one or more routing trees may be determined based on corresponding root nodes to reach a particular receiving node in a computer network. A delay value may be calculated at each node of the routing tree, the delay value inversely proportional to a distance between each respective node and the root node of the tree. Upon detecting a trigger at a particular node of the tree to transmit a stormed message to the particular receiving node (e.g., an alarm), the particular node may initiate a timer to count down the delay value in order to receive any upstream node stormed messages prior to expiration of the timer. The particular node may then coalesce the upstream node stormed messages with the stormed message of the particular node, and may transmit the coalesced stormed message downstream along the tree toward the particular receiving node upon expiration of the timer.

摘要： In one embodiment, an intermediate node of a computer network can receive a message intended for a destination. The message can include a header indicating a source route. The intermediate node can determine a routing entry for a routing entry for the destination associated with a next hop based on the source route and cache the routing entry. The intermediate node can further receive a second message intended for the destination that does not indicate the next hop, and transmit the second message according to the cached routing entry.

摘要： In one embodiment, a network of nodes is configured to communicate according to a configuration of Available Routing Construct (ARC) chains as well as monitoring communication in the network, and/or selectively controls whether or not provisioned particular links will be used. One embodiment colors nodes of the network (e.g., a wireless deterministic network) along different paths through the network and marks packets with the color of each traversed node to track a path taken by a packet. One embodiment sends a particular packet through the network and marks over which links the packet traverses and aggregates these traversed links of other copies of the particular packet. One embodiment controls whether or not the provisioned time slots are used based on flooding a control packet through the network with enable or disable information for each of these links.

One embodiment includes sending information, from a first network node in a network, during an exclusive transmission unit, wherein the exclusive transmission unit includes one or more wireless time slot-frequency pairings assigned to the first network node to send info nation without another assigned network transmission unit providing overlapping time slot-frequency interference from another network node communicating in the network. One embodiment includes sending information, from the first network node, during an overlapping transmission unit, wherein the overlapping transmission unit includes one or more wireless time slot-frequency pairings assigned to the first network node to send information, with the overlapping transmission unit overlapping in time slot-frequency with one or more other assigned network transmission units that will cause interference if simultaneously used.

摘要： A node in a Low power and Lossy Network (LLN) is managed by monitoring a routing configuration on a node in a LLN. A triggering parameter that is used to invoke an address change on a child node is tracked and a threshold against which to compare the triggering parameter is accessed. The triggering parameter is compared to the threshold. Based on results of comparing the triggering parameter to the threshold, it is determined that an address change at the child node is appropriate. An address change of a child node appearing in the routing configuration is invoked based on the determination that an address change is appropriate.

摘要： In one embodiment, a root device may request that one or more devices of a computer network build a directed acyclic graph (DAG) for routing traffic within the computer network based on an objective function (OF), where the OF has one or more metrics to optimize the DAG against and optionally certain constraints. Particular devices that receive the request may then build the DAG based on the OF, and may determine and report OF feedback to the root device. Upon receiving the reports regarding OF feedback, the root device may then adjust the OF based on the feedback, and request a rebuild of the DAG from the devices based on the adjusted OF.

摘要： In one embodiment, a node in a computer network may receive data of a particular type at a first frequency (e.g., a sensor in a sensor network), and may correspondingly determine whether there is at least one interested subscriber for the data of the particular type, where the interested subscriber desires the data at a second frequency. If there is an interested subscriber, buffered data publishing may be dynamically activated at the node in response to a ratio between the second and first frequencies being less than a configured threshold. In particular, buffered data publishing comprises buffering the received data and transmitting a latest received data to the interested subscriber at the second frequency.
