ONAP Scale Out 181002.mp4

Discussion

• Testing (Marco)

  • Early stages.  Still trying to get platform stable 

  • Tried pushing policies from CLAMP to Policy

    • Guard Policies did not work.  A fix is being developed

  • Marco will send more updates to Scott

• Dublin Work Flow

•  

  •  Scale In VM Decision

    • Decided to use LIFO for Dublin

    • OOF is the right strategy for making the decision

    • Should Policy, OOF, or SO determine the last VM added to the pool?

  • Pre Action

    • We will send the VNF a Pre-action signal for Scale In to allow the VNF to take care of VNF specific Tasks before the scale in action is done.

    • SO will wait for a response from the VNF before moving on to the next action in the workflow

  • Moving Traffic

    • Distribute_traffic will be used to move new traffic away from target VM

    • Quiesce_traffic will be used to signal when all existing traffic has been drained from target VM

    • Both Distribute_Traffic and Quiesce_Traffic will need to be modified to work at the VF_Module/VNFC level

  • Configuration

    • Not much changes here except for incorporating the use of Auto Configuration.  This will need to be done for Scale Out also

    • CDS should be ready in Dublin timeframe

    • We will need a new controller API for "ConfigScaleIn"

  •  Cleanup

  •  

    • Need to do a STOP VM before we terminate the VM so we do not corrupt any resources

    • All resources will be released and the next scale out will likely get a different set of resources.

• Dublin project level requirements

• Testing

  • Helen has asked for more detailed test cases

  • Marco will document tests he is running and then send them to Scott to add to the wiki page

• Prep and Post phases for Scale In

  • Scott will get back to Liu (Nokia) to explain what should be done by ONAP vs what should be done by the VNF.  once this is established we will need to determine if the VNF needs to be signaled for each phase and if a response is needed.

Discussion 

• Lauren going through email of beijing issues

•  

  1. Min/max comparison in VID.  The values were added to the vDNS model; Values need to be added for all VNFs that want to be scaled

  2. Missing records in A&AI 

  3.  

     1. Prov Status   

     2.  

        1. This is manual step that we fixed by using Robot 

        2. Update User Guide to ensure that provider knows to update Prov_Status

     3. IP addresses - affected HealthCheck and ConfigScaleOut   

     4.  

        1. IP Address  should be updated in A&AI when SDNC spins up new instance    

        2.  

           1. They may be in the wrong location of A&AI (Where is the correct location?)  

           2.  

              1. Very difficult to get the information.

  4. VID does not have memory of the number of VF Modules that it scales

  5.  

     1. Issue being addressed with VID

     2. VF_Module name appends the instance number

     3. Need to address this solution for Scale In issues

  6. Missing payload in APP-C request from SO - Requirements Gap

  7.  

     1. Is Config data passed to controller or does controller retrieve it?

  8. Controller type not being sent correctly from VID to SO

  9.  

     1. Controller_type should be in VNF Model (talk to SDC)

     2. There may be issues with SDC team

     3. In Beijing SO ignored value from VID and just hardcoded APPC

  10. Messages not being posted to DMaaP

  11.  

      1. Not sure if this a larger issue or if this is just something we stumbled on

      2. DMaaP says that the topic needs to be created before the message is sent

      3. Create a Jira item that describes issue we had.

  12. SDNC delivered partial Scale Out Requirements

  13.  

      1. SDNC needs to inherit APPC functionality for Casablanca

Discussion 

• Manual Scale Out Use Case is currently being tracked as a possible working Beijing Use Case

• Much progress has been made over the past week.

• Catherine Lefevre has been leading the charge to get the UC included in Beijing

• All VID issues appear to be fixed

• A Work Around is being developed for getting the IP Addresses to APPC for configuration of the VNF

  • The IP Addresses are not in AAI.  (SDNC will need to add these addresses in Casablanca)

  • SDNC will send the IP Addrs directly to SO after assignment

  • SO will include the addresses in its ConfigScaleOut() call to APPC/SDNC via DMaaP

• There is still some work to be done:

  • SO still needs to construct the ConfigScaleOut() Request and send it to DMaaP

  • APPC/SDNC needs to test this request

  • Healthcheck still needs to be tested. 

•  Current status can be found on the Testing Status Page

•  

  • APPC is expecting configuration file to be passed from VID through SO to APPC

•  Not enough time available to add new features

  • APPC does not have enough time to find config data in AAI (Preferred fix).  Will need to push to Casablanca

  • SO/VID does not have enough time to create pass-through of manual configuration data 

• Team to continue to test as much as possible within Beijing and report status on Wiki Page
