Abstract: In one embodiment, a method comprises creating, in a computing network, a loop-free routing topology comprising a plurality of routing arcs for reaching a destination network node; identifying, within the loop-free routing topology, non-congruent paths for a source network node to reach the destination node; and determining, from the non-congruent paths, a non-congruent path pair providing no more than a prescribed difference of latency from the source network node to the destination node, enabling the source network node to forward a data packet in a first direction of the one non-congruent path pair and a bicasted copy of the data packet in a second direction of the one non-congruent path pair, for reception of the data packet and the bicasted copy by the destination node within the prescribed difference of latency.

Abstract: In one embodiment, a method comprises receiving, by a network device in a deterministic data network comprising deterministic segments, a data packet comprising a packet header having a bit index, each bit in the bit index associated with a corresponding one of the deterministic segments; the network device identifying, from the bit index, a first bit for a corresponding first deterministic segment and a second bit for a corresponding second deterministic segment, wherein the network device is an endpoint for transmitting deterministic traffic into each of the first and second deterministic segments; the network device selectively executing a replication operation of the data packet for transmission of a replicated data packet into each of the first and second deterministic segments, based on the network device detecting the corresponding first and second bits set for replication.

Abstract: In one embodiment, a method comprises a network device identifying, in a time slotted network allocated timeslots for exclusive control of data transmissions with at least a second network device, a first schedule of first timeslots allocated for transmission and reception of packets having a first priority and a second schedule of second timeslots allocated for transmission and reception of packets having a second priority lower than the first priority, the second schedule overlapping the first schedule; and the network device shifting the second schedule of timeslots, relative to the first schedule, by a slot-frame shift (SFS) interval that causes a corresponding listen-before-talk interval in each of the second timeslots to be initiated coincident with or after transmission is enabled for any packet having the first priority.

Abstract: In one embodiment, a device in a network receives packet arrival information for a packet from a neighbor of the device in the network. The packet arrival information indicates a likelihood of the packet being received by a target node that is moving in the network were the packet forwarded by the neighbor to the target node. The device forwards the packet to the target node based on a determination that the device has a higher likelihood of the packet being received by target node were the packet forwarded by the device to the target node than were the packet forwarded by the neighbor to the target node.

Abstract: In one embodiment, a method comprises a first wireless network device identifying a deterministic receive slot reserved for reception of a first data packet from a second wireless network device along a deterministic track in a deterministic network; the first wireless network device transmitting an acknowledgement in the deterministic receive slot, to the second wireless network device, in response to successful reception of the first data packet in the deterministic receive slot; the first network device transmitting a second data packet in the deterministic receive slot, following the acknowledgement, to the second network device.

Abstract: In one embodiment, a method comprises: a root network device of a tree-based network topology identifying an instability in an identified child device attaching within the tree-based network topology; the root network device generating and storing in a routing information base table, for each sub-child device reachable via the identified child device, a corresponding source-route path starting with the identified child device and ending at the corresponding sub-child device; the root network device adding, to the routing information base table, a current path for reaching the identified child device, enabling the root network device to generate a path for reaching any one sub-child device using the corresponding source-route path via the current path of the identified child device.

Abstract: In one embodiment, a networking device in a local area network (LAN) establishes a virtual network overlay in the LAN to redirect traffic associated with a particular node in the LAN to a server for analysis. The networking device receives an indication from the server that at least a portion of the traffic associated with the particular node is trusted for local sending within the LAN and adjusts the virtual network overlay to locally send the trusted portion of the traffic associated with the particular node to one or more other nodes in the LAN without redirection to the server. The networking device collects characteristic information regarding the trusted portion of the traffic sent locally within the LAN via the adjusted virtual network overlay and sends the collected characteristic information to the server for analysis.

Abstract: In one embodiment, a networking device in a local area network (LAN) receives an instruction from a server to form a virtual network overlay in the LAN that redirects traffic associated with a particular node in the LAN to the server for analysis. The networking device establishes the virtual network overlay in the LAN to redirect traffic associated with the particular node to the server. The networking device determines that at least a portion of the traffic associated with the particular node should be processed locally within the LAN and not via redirection to the server and adjusts the virtual network overlay to process the at least a portion of the traffic associated with the particular node locally within the LAN and not via redirection to the server.
