Abstract: Various example embodiments for supporting deterministic communications in communication networks may be based on use of a hybrid Programming Protocol-Independent Packet Processor (P4) deterministic switch. The hybrid P4 deterministic switch may include an electronic communication element configured to compensate for the jitter of incoming traffic to match a desired level of jitter for end-to-end deterministic communication of the incoming traffic and an optical communication element configured to support optical propagation of deterministic traffic received from the electronic communication element. The electronic communication element may include electronic packet queues, programmable electronic schedulers serving the electronic packet queues, and a P4 control element, where the electronic packet queues, the programmable electronic schedulers, and the P4 control element cooperate to support end-to-end deterministic communication of traffic based on control plane programming of the programmable electronic schedulers to serve the electronic packet queues in a manner providing end-to-end deterministic communication of the traffic.
