Abstract: In one embodiment, a method comprises: receiving, by a transport layer executed by a processor circuit in an apparatus, a flow of application data having been originated by an executable application; storing, by the transport layer, the application data as transport layer packets in a buffer circuit in the apparatus, each transport layer packet having a corresponding transport sequence identifier identifying a corresponding position of the transport layer packet relative to a transmit order of the transport layer packets; and causing, by the transport layer, a plurality of deterministic network interface circuits to deterministically retrieve the transport layer packets, in the transmit order, from the buffer circuit for deterministic transmission across respective deterministic links, the transport sequence identifiers enabling a destination transport layer to recover the transmit order of the transport layer following the deterministic transmission across the deterministic links, regardless of order of reception by the destination transport layer.

Abstract: In one embodiment, a method comprises: promiscuously detecting, by a parent network device in a tree-based network topology, a data packet transmitted to a child network device attached to the parent network device, the data packet transmitted by a grandchild network device attached to the child network device; determining, by the parent network device, whether the data packet transmitted to the child network device is to be forwarded toward a destination via the parent network device; and the parent network device selectively initiating intercepted forwarding of the data packet toward the destination, on behalf of the child network device, based on determining that the data packet is to be forwarded toward the destination via the parent network device.
