A. VFC-NSLCM calls VFC-GVNFM driver through RESTful api to create VNF.

B. VFC-GVNFM invokes VFC-VNFLCM through RESTful api to do the

creation(which requires bunch of time) and returns the VNF information(Almost synchronous).

( I. VFC-LCM calls VFC-GVNFM to apply for grant.

  J. VFC-GVNFM driver invokes VFC-NSLCM to provide the grant info.

  K. VFC-NSLCM provides grant info along with placement from OOF to VFC-GVNFM driver

  L. VFC-GVNFM transmits the information to VFC-VNFLCM to go through

     the following steps for instantiation.)

During the creation period(Step B.):

C. VFC-NSLCM calls OOF for homing allocation service using the VNF information returned.

D. OOF calls POLICY to retrieve related policies for such service/VNF.

E. OOF calls AAI to get all available cloud regions or existing instances inside the database.

F. OOF processes the homing allocation.

G. OOF respond to VFC-NSLCM with the optimal placement.
