Abstract: In one embodiment, a method comprises: classifying, by a controller device, a first access point device in a WLAN as a leader access point for a wireless client device, and at least a second access point device as a follower access point; and allocating, to the leader access point, a shortened medium access control layer timer (“timer”) that is shorter than a prescribed timer used by the follower access point, the shortened timer causing the leader access point to respond to reception of a wireless data packet from the wireless client device by transmitting an acknowledgment to the wireless client device upon expiration of the shortened timer; the prescribed timer causing the follower access point to defer to the leader access point based on the follower access point waiting for at least expiration of the prescribed timer before selectively transmitting a corresponding acknowledgment in response to receiving the wireless data packet.

Abstract: In one embodiment, a method comprises: identifying, by a low power and lossy network (LLN) device in a low power and lossy network, a minimum distance value and a distance limit value for limiting multicast propagation, initiated at the LLN device, of a multicast data message in the LLN; and multicast transmitting, by the LLN device, the multicast data message with a current distance field specifying the minimum distance value and a distance limit field specifying the distance limit value, the multicast transmitting causing a receiving LLN device having a corresponding rank in the LLN to respond to the multicast data message by: (1) determining an updated distance based on adding to the current distance field a rank difference between the receiving LLN device and the LLN device, and (2) selectively retransmitting the multicast data message if the updated distance is less than the distance limit value.

Abstract: In one embodiment, a method comprises: generating, by a constrained low power and lossy network (LLN) device that is localized within a subregion of an LLN, a thin destination oriented directed acyclic graph (DODAG) having up to a prescribed limit of attached LLN devices at each hop of the thin DODAG based on generating a DODAG information object (DIO) message specifying an instruction for limiting attachment at each hop of the thin DODAG to the prescribed limit; and causing, by the constrained LLN device, multicast-only transmissions via the thin DODAG based on inserting into the DIO message a multicast-only transmission mode via the thin DODAG and outputting the DIO message, the DIO message causing each neighboring LLN device to selectively attach to the constrained LLN device as an attached child LLN device based on the instruction and execute the multicast-only transmissions via the thin DODAG.

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.
