 require-instance

  • Sync #16  | Method for managing require-instance statements to found → Proposal made - TR531 already describes the mechanism 
  • VLAN-IF #28 | require-instance==false at object-creation- and attribute-value-changed-notification manually corrected - proposal made - to be rejected
  • VLAN-FD #19 | require-instance==false at object-creation- and attribute-value-changed-notification manually corrected - proposal made - to be rejected
  • VLAN-FC #6 | require-instance==false at object-creation- and attribute-value-changed-notification manually corrected - proposal made - to be rejected

The mechanism is required for AttributeValueChange Notification and ObjectCreate Notification but not for ObjectDeletion Notification

@Prathiba is going to check for other cases

Thorsten Heinze : Is an issues required for all UMLs?

The stereotype Lifecycle Aggregate Association should be added to all shared Association for AttributeValueChange Notification and ObjectCreate Notification.   

In RPCs all references should be tagged with require-instance==false (as today - no change)


The statement above

  • the mechanism is required for AttributeValueChange Notification and ObjectCreate Notification, ...

should be reverted. Reason is that the asynchrous implementation of the NETCONF server can not guarantee the exactions of an instance. This will simplify the implementation.

As a consequence all open issues in this regard can be "rejected" as there is no change in UML and UML2YANG needed. 

All leafrefs will be tagged with "required-instance = false". 


00:30Modelling Roadmap

all, Nader Zein 

latest version in wiki:
Q: timeline?

Modelling Roadmap

update sequence to pre-MW-2.0-yangs

all currently implemented pre-TR532 2.0 -> PACs (existing today, including RMON, PM)

Sync and the updates of the CoreModel 1.4 yang (target to be available as YANG in 2022-10)

Centralized Alarm List (available now)

Mediator Instance Manager (available now) (REST for Mediators not for devices) (reusable component to be prepared)

based on the ApplicationPattern


proposed official ONF TR532 2.0

Sync and the updates of the CoreModel 1.4 yang

Centralized Alarm List - needs to be in 2.0 because it has impact on all PACs

Equipment Augment Module

all currently implemented pre-TR532 2.0 -> PACs

Mediator Instance Manager (REST)

LLDP -> related automatic link discovery


proposed official ONF TR532 2.1

Backup and Restore

SVLAN

proposed official ONF TR532 3.0

CoreModel 1.6

NMDA alternative

Target: start ONF review mid of November 2022 for TR532 2.0

Next Steps towards 2.0

  • UML (almost done)
  • YANG (to be updated and generated: revision 2023-06-?? including the core-model)
  • YANG Tests
  • init implementation and test with the current test functions
  • feedback from Implementation to UML/YANG and iterate
  • Creation of TR-532 v2.0
    • with references to UML - gendoc
    • with references to yang ?
    • creating the (word) documentation
