ATT scenario subscriber add/remove: synchronize flow add with delayed tech profile handling

    XMLWordPrintable

    Details

      Description

      In ATT scenario during the configuration of subscriber flow add and remove the expected tech profile configuration (remove GemPorts and T-Cont and new profile configuration) is delayed in reference to the needed flow removal and flow adding. In current implementation this has the effect that

      • OMCI flow add activity is done based on a valid existing TechProfile, which will be later removed again (before addigng it again). The danger here is, that on the ONU according OMCI ME references get lost
      • the final state, that is indicated at the end of the sequence is 'tech-profile-config-download-success' while the expectation is 'omci_flows-pushed'

      In a solution this behavior of the connected voltha subsystems shall be mitigated by synchronizing the flow remove/add sequence with the expected TechProfile deletion (while the code must take into consideration, that there a situations where the Techprofile removal is really not done [disabled ONU])
