This page describes how to test demonstrate the entire flow from Non-RT RIC Controlpanel → Policy Agent →  A1 controller in SDNC -> Near-Realtime RIC Simulator

Overview of the End to End call

Details of the architecture can be found from the following link: Release B

End to End call from Dashboard to Near-RT RIC simulator

Preparation

• Download the SDNC repo: 

       git clone "https://gerrit.o-ran-sc.org/r/nonrtric"

• The SDNC A1 Controller could be found in this repo.
• Download the sim/a1-interface repo:

       git clone "https://gerrit.o-ran-sc.org/r/sim/a1-interface"

• The near RT RIC simulator could be found in this repo.

Build SDNC project 

• Enter into the sdnc-a1-controller project, northbound and oam project will be listed. 

       near-rt-ric-simulator sdnc-a1-controller

...

  mvn clean install -Dmaven.test.skip=true

...

  mvn clean install -Dmaven.test.skip=true -P docker

...

  nonrtric/sdnc-a1-controller/oam/installation/src/main/yaml

...

Start Simulator:

• Go to the simulator project directory  a1-interface/near-rt-ric-simulator/scripts
• Create a docker image called nearric-simulator:1.0.0-SNAPSHOT: 

    docker build -t nearric-simulator:1.0.0-SNAPSHOT . 

• Run the Simulator in a docker container with a nearric-sim as name and attach to a 'yaml_default' network, to which SDNC is also attached.
  Set the env '-e A1_VERSION=<a1-interface-version>' in the command below  and replace '<a1-interface-version> with the desired A1 interface version. The simulator currently supports A1 yaml interface versions: 'OSC_2.1.0' and 'STD_1.1.3'
  

    docker run -p 8080:8085 --network=yaml_default -e A1_VERSION=<a1-interface-version> --name=nearRtRic-sim1 nearric-simulator:1.0.0-SNAPSHOT

Make a call from Open Daylight GUI to Simulator :

• Use browser to http://localhost:8282/apidoc/explorer/index.html#!/NONRT-RIC-API(2019-09-26)
• if password asked, find the related password and username at :

    nonrtric/sdnc-a1-controller/oam/installation/sdnc/src/main/scripts/startODL.sh

  check the username and password 

    ODL_ADMIN_USERNAME
    ODL_ADMIN_PASSWORD

• Make a call in the A1-ADAPTER-API:

check file: nonrtric/sdnc-a1-controller/northbound/nonrt-ric-api/provider/src/main/resources/NearRtRicList.properties

NearRtRic1 = nearRtRic-sim1:8080
NearRtRic2 = nearRtRic-sim2:8080

update value:

"A1-ADAPTER-API:near-rt-ric-id": "NearRtRic1"

See Release B - Build/Run for building and starting the environment.

Perform Policy Operations via Dashboard

• Open Dashboard UI at http://localhost:8080/

Image Added

• Click on Config and the screen below with STD_QosNudging_0.2.0 policy type should open

Image Added

• Click on '+' icon to create new policy

Image Added

• Choose your ric (ric1 or ric2) from drop-down menu and provide any arbitrary values for QoS Id, Ue Id and Priority

Image Added

• Submit the policy (you then need to also press Close to return from creation view)
• An entry to the chosen Near-RT RIC simulator console/log should appear (see, for example, docker logs ric1 in case ric1 policy was created):

172.18.0.6 - - [20/Apr/2020 07:56:04] "PUT /a1-p/policytypes/123/policies/58157215-6182-4fea-a9b4-f3814fbf91eb HTTP/1.1" 202 - 

• You may repeat the creation process a few times for different rics - below we see one policy created to ric1 and two to ric2

Image Added

• Click the pen icon to modify any policy

Image Added

• Modifications are submitted in the same way as in creation, and the resulting simulator log should also be same as the one we saw in creation

172.18.0.6 - - [20/Apr/2020 07:58:12] "PUT /a1-p/policytypes/123/policies/377ac417-5e1e-4088-81cd-f4a5549f79fa HTTP/1.1" 202 -

Image Added

• Delete any policy by clicking the red trashcan icon

Image Added

• Confirm deletion and verify the log on simulator side:

172.18.0.6 - - [20/Apr/2020 08:02:19] "DELETE /a1-p/policytypes/123/policies/b204bd1d-f28c-4a05-bb4c-82d49a1b1e12 HTTP/1.1" 202 -
