摘要： In one embodiment, an initial path is established in a wireless deterministic network between a source and a destination through one or more intermediate nodes, which are typically informed of a required metric between the source and the destination for communicating a packet. The initial path is locally (e.g., without contacting a path computation engine) reconfigured to bypass at least one of the intermediate nodes creating a new path, with the new path meeting the requirement(s) of the metric. Note, “locally reconfiguring” refers to the network nodes themselves determining a replacement path without reliance on a path computation engine or other entity (e.g., network management system, operating support system) in determining the replacement path. In one embodiment, a network node not on the initial path replaces a node on the initial path while using the same receive and send timeslots used in the initial path.

摘要： In one embodiment, sensor data is transported in a network to a rendezvous point network node, which consolidates the information into a consolidated result which is communicated to the destination. Such consolidation by a network node reduces the number of paths required in the network between the sensors and the destination. One embodiment includes acquiring, by each of a plurality of originating nodes in a wireless deterministic network, external data related to a same physical event; communicating through the network said external data from each of the plurality of originating nodes to a rendezvous point network node (RP) within the network; processing, by the RP, said external data from each of the plurality of originating nodes to produce a consolidated result; and communicating the consolidated result to a destination node of the network. In one embodiment, the network is a low power lossy network (LLN).

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.

摘要： In one embodiment, a mobile router receives a multicast-supported router advertisement message from an attachment mobile router in a mobile ad hoc network, the multicast-supported router advertisement message specifying an attachment prefix and a multicast-capable identifier. The mobile router attaches to the attachment mobile router in response to the multicast-supported router advertisement message and according to a protocol requiring establishment in the mobile ad hoc network of a tree topology having a single multicast clusterhead, and selects a default attachment address within an address space of the attachment prefix. The mobile router receives a multicast request, from an attached node, for receiving a multicast stream, and the mobile router outputs a neighbor advertisement message with multicast extension, to the attachment router, that specifies that access to the multicast stream is requested via the default attachment address.

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 first router attaches to an attachment router based on detecting a first router advertisement message specifying an attachment prefix and a first tree information option. The first tree information option includes a first IP host address of a first clusterhead having established a first tree topology. The first router receives a second advertisement from a second router specifying a second address prefix, distinct from the attachment prefix and the first address prefix of the first router, and a second tree information option specifying a second IP host address of a second clusterhead having established a second distinct tree topology. If the first and second routers are at equal depths relative to the respective first and second clusterheads, routing information is shared, including first address prefix reachable via the first router, and a host route for reaching the first IP host address via the first router.
