Summary0005382: Extension of PubSubState state machine with new state Enabling
Description

Based on feedback from the TSN working group, we need an additional state in the PubSubState state machine that indicates that the transition from Disabled/Stopped to Operational takes some time e.g. to establish the TSN streams necessary for communication. This may also be of interest for other transport protocols e.g. if the Publisher or Subscriber needs to establish a connection to a message broker.

We discussed this in the December 2019 F2F meeting in Phoenix and decided to extend the state machine.
See meeting minutes and meeting folder for more information and presentations.
