---TEST STATUS for Dublin Release ----

Use Case 1:

Event-driven bulk transfer of monitoring data from an xNF to ONAP/DCAE. A micro-service will listen for 'FileReady' VES events sent from an xNF via the VES collector. Once files become available the collector micro-service will fetch them using protocol such as FTPES or SFTP. The collected data files are published internally on a DMaaP Data Router (DR) feed.  A File Consumer node which is a simulated PM file subscriber that subscribe to Data Router feed and receive PM files.





Use Case 2:

Event-driven bulk transfer of monitoring data from an xNF to ONAP/DCAE. A micro-service will listen for 'FileReady' VES events sent from an xNF via the VES collector. Once files become available the collector micro-service will fetch them using protocol such as FTPES or SFTP. The collected data files are published internally on a DMaaP Data Router (DR) feed.  The PM mapper receives the files by subscribing to a Data Router feed. The 3GPP PM Mapper micro-service will extract selected (filtered) measurements from a 3GPP XML file and publish them as VES events on a DMaaP Message Router topic for consumers that prefer such data in perf3gpp VES format.

Deployment:

Test environment requirements for above test cases:

  • xNF simulator for test cases:  FTPes capable server.
  • with VES 7.0.1 support for 'fileReady' event.
    • E.g. xNF able to produce data files and send VES fileReady events,
    • E.g. xNF emulator able to produce 'fileReady' notification events including updated events, or a series or predefined VES events at periodic intervals.
  • sample data files for collection. E.g. 3gpp PM file(s)
  • DMaaP R3, at minimum need DR running and configured for Bulk PM support
  • DCAE R3, MR with support for VES 7.1 spec
  • DCAE R3, Data File Collector installed and configured

This environment can be set up by following the steps below.

  1. Clone the integration/csit repo (git clone ssh://gerrit.onap.org:29418/integration/csit ).
  2. Run: .run-csit.sh plans/usecases/5G-bulkpm

Next Step(s):

Write Tests cases to verify BulkPM on an ONAP environment.

Performance Verification:


  • To arrive at the xNF’s that 5G - Bulk PM E2E can handle, two scenarios must be fulfilled and measured.

1.X Number of xNF’s sending a VES FileReady Event every 15 minutes to an ONAP until PM-Mapper has finished processing the last PM file that was sent in that ROP.

2.ONAP looses connection to X Number of xNF’s and ONAP gains re-connection to the xNF after 1 day, this gives a maximum number of new PM files in the VES FileReady event 96*X Number of xNF’s.


1.When adding 70 new xNF’s every 1.5hours to mimic xNFs being added to an ONAP deployment up to 420 xNF (420 new PM files every 15 minutes) , it takes 4 minutes for all the 420 xNF PM Files to be processed in the Bulk PM e2e Flow.

2.For a spike of 420 xNF’s, its took Bulk PM 5 hours to process the backlog i.e all the initial 40,320 (96* 420) PM files and 420 new PM files every 15 minutes.


For more information on how the 420 xNF's was obtained see the slidepack Integration Meeting.pptx
