  $ According to the dependencies mentioned in the NSD templated the VNF's will be launched.
  
  $ After launching the non-dependent VNF/VNF's for a network service, VNFManager is created which takes care of configuring the VNF through managment network if required.
  
  $ Once the configuration of non-dependent VNF/VNF's are done, an acknowledgement will be sent to VNFSVC service.
    After receiving the acknowledgement by VNFSVC service, it will resolve the next level of dependencies and then deploy those.
    This will be repeated until all the mentioned VNFS are deployed.
  
  $ Refer verification file in respective folders and follow the mentioned steps to verify the deployed Network Service.
