TRANSPORT LAYER IDENTIFYING FAILURE CAUSE AND MITIGATION FOR DETERMINISTIC TRANSPORT ACROSS MULTIPLE DETERMINISTIC DATA LINKS

摘要

In one embodiment, a method comprises: detecting, by a transport layer executed by a processor circuit in an apparatus, a request message received via a non-deterministic data link from one of a plurality of deterministic network interface circuits, the request message for a transport layer packet having been stored in a buffer circuit storing a plurality of transport layer packets in the apparatus, the deterministic network interface circuits providing respective deterministic links for deterministic transmission of the transport layer packets in a deterministic data network, the request message specifying a first number identifying any missed transmission opportunities on the corresponding deterministic link; determining, by the transport layer, a cause of failure in one or more of the missed transmission opportunities; and selectively executing, by the transport layer based on determining the cause of failure, a corrective action for preventing an increase in latency of the transport layer packets.
