Example: TOSCA service template
•This example illustrates a 5G NS contains two VNFs: CU-UP, CU-CP, connected through NsVirtualLink_F1U/E1/F1C/SnU./XnC/NgC/X2C.
•There are may be 1-N of the VnfExtCp of CU-UP and Cu-CP are exposed as the Sap of this NS.
•The flavour_id is "simple".
•DU_1_to_N : a dependency requirement to CU-UP, CU-CP, which indicates that all the instances of CU-UP, CU-CP have to be deployed first before deploy the instances of DU_1_to_N.
