The following fixes were tested on scenario 2 (e.g. External NSSMFs), non-shared slice.

We tested the use case with the following OOM configuration:

  • oom Honolulu with the following changes:
    • SO
      • bpmn-infra at 1.9.0 (in order to fix UUI Slicing Management Section issue)


or


  • oom master from 09-02-2021 (it should be good all version with AAI v23 enabled) with the following changes:
    • AAI (v23 schema should be enabled):
      • aai-schema-service 1.8.6
      • aai-traversal at 1.8.0
    • SO
      • api handler infra at 1.8.1
      • nssmf-adapter at 1.8.0
      • bpmn-infra at 1.8.0
    • SDNC

For configuration, we used the instructions reported in points 2, 3, 4, 5, 6, 7 at Install Minimum Scope for Option 1

For onboarding phase, plese use this guide Template Design for Option2 with the following fix:

  • Fill in the "Service Role" field with the value "ONAP_internal" (in the General section, in SDC ) for the resources: Tn_ONAP_internal_BH
  • Fill in the "Service Role" field with the value "huawei" (in the General section, in SDC ) for the resources: EmbbCn_External, EmbbAn_NF
  • Fill in the "Service Role" field with the value "option2" (in the General section, in SDC ) for the resources: EmbbNst_O2
  • Fill in the "Service Type" field with the value "embb" (in the General section, in SDC ) for the resources: Tn_ONAP_internal_BH, EmbbAn_NF, EmbbCn_External, CST_O2
  • Fill in the "Vendor Name" field with the value "huawei" (in the General section, in SDC ) for the resources: EmbbCn_External_AR, EmbbAn_NF_AR

NSI SelectionCamel_to_snake/snake_to_camel schema is wrongOOF

You will need to change several params into slicing_config.yaml file inside OOF container 

A working slicing_config.yaml is :

slicing_config.yaml

You need to restart the OOF docker container once you updated the slicing_config.yaml, you can do it using the following steps,

  • Login to the worker VM where the OOF container is running. You can find the worker node by running (kubectl get pods -n onap -o wide | grep dev-oof)
  • Find the container using docker ps | grep optf-osdf
  • Restart the container using docker restart <container id>


NSI SelectionPolicies from WIKI page are wrong. The NSI selection response from OOF does not contain all information in order to create the Slice Management Task properlyDOCS/POLICY

new policies  must be used

policies.zip

and for NSI policies, please use the following:

nsi_policies.zip


Follow the points Optimization Policy Creation Steps in order to create and push the new policies (both nsi and nssi).

RANSimulatorUse the jssecacerts cert from sdnc container (var/custom-certs) and place it in ransim package under ransim/docker/config/ransim. It needs  to be replaced as it expires over time.

or

1.Download the SDNR cacerts from browser.

2.Import the cacerts into RANsim 

 keytool -import -noprompt -trustcacerts -alias SNDC -file <certsfile> -keystore /ransim/docker/config/ransim/jssecacerts -storepass changeit

How download cacerts from browser?

  1. Login to firefox browser 
  2. Click on the lock icon in address url
  3. Click on more information
  4. Click on Security then view certificate
  5.  PEM (cert) PEM(chain) from both SDNC and intermediateCA_9

    Hi,

       Can you provide a workaround for the below issues mentioned above.

    NSI SelectionCamel_to_snake/snake_to_camel schema is wrong : Can you provide the working slicing_config.yaml 
    NSI Selection

    Policies from WIKI page are wrong. The NSI selection response from OOF does not contain all information in order to create the Slice Management Task properly

    Question: Where do we copy these ZIP files ? is this the link with details Optimization Policy Creation Steps 

  2. Aniello Paolo Malinconico

    Hi Rajendra Prasad Mishra, I have uploaded a working slicing_config.yaml file, containing the camel to snake mapping.
    For policies, you can follow this guide Optimization Policy Creation Steps using the policies.zip file uploaded here.

    Thanks,

    Aniello

      Hi, is it shared or non-shared scenario?

      Thanks,

      1. Elangovan Thanasekaran

        Hi Aniello Paolo Malinconico ,

        It is for non-shared scenario.

        1. Aniello Paolo Malinconico

          I think you have not used the latest policies.zip file uploaded here . 

          I have checked the policies.zip file and there are no occurrences of "exp_data_rate_dl" param ....

          Can you check?

          Aniello

    Hi Aniello Paolo Malinconico ,

    I can see the entry for exp_data_rate_dl as below in the optimization_nsi_non_shared.json file in policies.zip folder.


    exp_data_rate_dl{
        "minimizeLatency_{{ service_name }}": {

    Hi Aniello Paolo Malinconico ,

    Thank you so much for sharing the latest policies.zip file. This resolved all the "undefined" errors from OOF. 

    Currently we are getting empty solutions list from OOF for NSI selection response. Can you please let us know if you have any information on this.


    NSI oofResponse is: {"requestId": "9fd98f41-dbec-4414-81c0-3d32f2e99e81", "transactionId": "9fd98f41-dbec-4414-81c0-3d32f2e99e81", "requestStatus": "completed", "statusMessage": "", "solutions": []}

      If I remember well, for non-shared case, OOF response is an empty solution . So it should be a good response.

      Thanks,
      Aniello

    Hi Aniello Paolo Malinconico ,

    As per the existing logs attached, this is the expected response from OOF is below. existingNSI flag will be false and newNSISolution having sliceProfiles. But we are getting empty solutions response.

    Regards,

    1. Aniello Paolo Malinconico

      Hi,

      you are right... OOF NSI response should not return an empty array .
      Can you see this JIRA https://jira.onap.org/projects/OPTFRA/issues/OPTFRA-970 ? In the comment section, I had a similar issue (no solution returned) and it was a mismatch type of an NSTO1 param during SDC onboarding ...

      Let me know if solved.

      Regards,

      Aniello
