Abstract: In one embodiment, a method comprises: receiving, by a switching device, one or more identified flows of data packets from first deterministic flows of a first deterministic segment in a first deterministic domain, the first deterministic segment established based on first deterministic attributes in the first deterministic domain; receiving, by the switching device, second deterministic attributes about second deterministic flows for a second deterministic segment in a second different deterministic domain, the second deterministic attributes different than the first deterministic attributes; and allocating, by the switching device based on the first deterministic attributes and the second deterministic attributes, at least a portion of the second deterministic flows for deterministic stitching of the one or more identified flows of data packets from the first deterministic segment in the first deterministic domain into the second deterministic segment in the second deterministic domain according to a guaranteed deterministic constraint.

Abstract: According to one or more embodiments of the disclosure, a first tunnel router may receive a reservation request to establish a deterministic path between a first node and a second node. The first tunnel router may determine, based on the reservation request, a destination address of the second node. The first tunnel router may identify, based on the destination address of the second node, a second tunnel router associated with the second node. The first tunnel router may encapsulate a deterministic packet sent by the first towards the second node into a tunnel packet, wherein a multicast address in a header of the tunnel packet is set to the destination address of the second node. The first tunnel router can forward the tunnel packet along the deterministic path. The multicast address in the header of the tunnel packet causes nodes to send the tunnel packet according to the deterministic path.
