Abstract: Various embodiments relate to a path computation element (PCE) configured to control a network having ingress edge nodes, interior nodes, and egress edge nodes, including: a network interface configured to communicate with the network; a memory; and a processor coupled to the memory and the network interface, wherein the processor is further configured to: receive a request for a first continuous guaranteed latency (CGL) flow to be carried by the network; make routing and admission control decisions for the requested first CGL flow without provisioning of the first CGL flow and the configuration of schedulers in the interior nodes of the network; and provide flow shaping parameters to a flow shaper at an ingress edge node of the first CGL flow.

Abstract: Various example embodiments for supporting flow reliability in deterministic networking are presented. Various example embodiments for supporting flow reliability in deterministic networking may be configured to support flow reliability in deterministic networking based on control over frame replication and elimination for deterministic flows. Various example embodiments for supporting flow reliability in deterministic networking based on control over frame replication and elimination for deterministic flows may be configured to control replication and elimination of redundant flows providing redundancy for deterministic flows based on dynamic activation and deactivation of the redundant flows based on monitoring of flow continuity of the deterministic flows. Various example embodiments for supporting flow reliability in deterministic networking based on control over frame replication and elimination for deterministic flows may be configured to support flow reliability in deterministic networking for non-hierarchical networks or hierarchical networks.
