Summary
-------

The O1 interface simulator is a framework that provides simulated devices with a management plane exposed through a NETCONF/YANG interface, using the O-RAN O1 interface YANG modules.


Release Data
------------
version 1.0.3

[fixed] fixed issues where ODL could not parse the correct versions for yang files


version 1.0.2

[fixed] bug that occured when trying to start a wrong instance (bad docker-repository or docker-tag)
[fixed] when populating the fault-delay-list, if the sum of all the faults was 0, the network funciton kept on generating faults and crashed


version 1.0.1

[feature-add] added web-cut-through feature
[fixed] mount-point-addressing-method was mistakenly changing after starting


version 1.0.0
Initial release.

Feature Additions
^^^^^^^^^^^^^^^^^
* IPv6 for the simulated devices
* NETCONF CallHome for the simulated devices
* Manual notification generation
* Custom naming of the simulated devices

Bug Corrections
^^^^^^^^^^^^^^^
* `ssh-connections` and `tls-connections` leafs are now removed from the simulator-config
* `fault-notification-delay-period` has now the attribute `ordered-by user`

Deliverables
^^^^^^^^^^^^

Software Deliverables
+++++++++++++++++++++

The following docker containers are the resulting artefacts of the sim-o1-project:

* **o-ran-sc/ntsim-manager** - this image contains the NTS Manager, which handles the simulation environment;

* **o-ran-sc/ntsim-o-ran-ru-fh** - this image contains a simulated device which exposes a management interface via NETCONF/YANG, implementing the O1 FH interface specifications;

* **o-ran-sc/ntsim-x-ran** - this image contains a simulated device which exposes a management interface via NETCONF/YANG, implementing the X-RAN Management interface.
