Abstract: In one embodiment, a method comprises receiving, by a transport layer executed by a processor circuit in an apparatus, an identifiable grouping of data; storing, by the transport layer, the data as transport layer packets in a buffer circuit in the apparatus, the storing including inserting into each transport layer packet a grouping identifier that identifies the transport layer packets as belonging to the identifiable grouping; and causing, by the transport layer, a plurality of transmitting deterministic network interface circuits to deterministically retrieve the transport layer packets from the buffer circuit for deterministic transmission across respective deterministic links, the grouping identifier enabling receiving deterministic network interface circuits to group the received transport layer packets, regardless of deterministic link, into a single processing group for a next receiving transport layer.

Abstract: In one embodiment, a method comprises determining a movable network device is moving along a repeatable sequence of access point devices in a deterministic network; and establishing a deterministic track along the repeatable sequence of access point devices, the deterministic track comprising insertion slots allocated for insertion of a data packet, by the movable network device, into the deterministic track via any one of the respective access point devices.

Abstract: In one embodiment, a method comprises: determining access point devices providing network coverage for a mobile network device within a prescribed coverage area of a deterministic network; establishing a deterministic reception tree comprising a root and switching devices associated with the access point devices, the deterministic reception tree enabling any one or more of the switching devices to forward toward the root a data packet, transmitted by the mobile network device at a prescribed transmission time, for deterministic reception by the root at a prescribed reception time regardless of any distance of any of the access point devices from the root; and causing the switching devices to implement the deterministic reception tree enabling the root to deterministically receive the data packet, received by any one or more of the access point devices, at the prescribed reception time.

Abstract: In one embodiment, a method comprises identifying, by a path computation element, essential parent devices from a nonstoring destination oriented directed acyclic graph (DODAG) topology as dominating set members belonging to a dominating set; receiving, by the path computation element, an advertisement message specifying a first dominating set member having reachability to a second dominating set member, the reachability distinct from the nonstoring DODAG topology; and generating, by the path computation element based on the advertisement message, an optimized path for reaching a destination network device in the nonstoring DODAG topology via a selected sequence of dominating set members, the optimized path providing cut-through optimization across the nonstoring DODAG topology.

Abstract: In one embodiment, a method comprises: a first network device in a deterministic network identifying first and second slots for transmission of a data packet toward a destination device along a deterministic track of the deterministic network, the first slot reserved for the first network device receiving the data packet from a second network device and the second slot reserved for transmission by the first network device of the data packet toward the destination device along the deterministic track; the first network device detecting, in the first slot, an absence of receiving the data packet from the second network device; and the first network device selectively generating and transmitting in the second slot, in response to the absence of receiving the data packet, a management packet along the deterministic track.
