Current Status

  1. The Use Case is now functional in the test laps and is ready for the Casablanca release

  2. There is still some non-blocking testing that must be done to show the test case works using SDNC as the VNF Controller

100% complete and tested using the latest released docker images as of 11/25/2018.
