get nsdId, nsName and nsDescription, context (globalCustomerId, serivceType) parameters
get a ns package by the given nsdId from ETSI Catalog Manager
check if ns instance exists from the NFVO_NSINST database table
- if it exists, log it exists
create an ns instance id (uuid) and store it with other nsd info, status (NOT_INSTANTIATED) to NFVO_NSINST database table
create an ns instance record (service-instance-id, service-instance-name, service-type, service-role) in AAI
get nsInstance from GetNSInfoService
return 201 Created with the NsInstance
Send NsIdentifierCreationNotification

NsLcmOperationOccurrenceNotification (Start/Processing/Completed)

VFC Design

Get an ns instance id from the parameter
create a job for the ns instance id
create an occ id for the ns instance id
Update the ns instance id row of the NFVO_NSINST database table for status (= INSTANTIATING)
get a ns instance data from the NFVO_NSINST for the ns instance id
get and store additional Parameters for NS
get an VIM id from the cloud owner and cloud region parameters
get an VNF VIM from he location constraints
set the job status with 'Start Query NSD'
get and parse a nsd for the ns package id
modify nsd state
get VNF list from the nsd
for each VNF,
- get vnfd_id, vnfm_type, vimId, s_vimId (with "cloud_owner"_"cloud_regionid")
- select VNFM by leveraging AAI ESR
- store VNF pararms in collection, with vnf info including vnfmInstanceId
set vl vim id
- for each VNF
  - if VNF has dependencies, for each dependency
    - add VNF properties and id into vl_vnf array
- for each VLs
  - get vnfdId and vimId
  - add vimId into VL array
update NFVO_NSINST with the nsd model
get PNF parameters
get VNF parameters (from VNF params above)
set up Plan Input with job_id, ns_inst_id, tosca plan, additional NS params, VNF params, PNF params)
start workflows with the job_id, ns_inst, plan_input, occ_id)
- get service template id from ETSI Catalog Manager
- get process id from ETSI Catalog Manager
- workflow run with data (process id, params = plan input)
  - createVL
  - createVNF
  - createSFC (Service Function Chain)

NsLcmOperationOccurrenceNotification (Start/Processing/Completed)

VFC Design

Get an ns_inst_d, job_id and request_data from the parameters
if there no matching ns_inst_id from the NFVO_NSINT database table, consider there is nothing to terminate, and return
set job status as "Starting terminate..."
update the ns_inst_id row from the NFVO_NSINST database table with the status = TERMINATING
cancel SFC list
- get sfc inst array
- for each sfc inst
  - DELETE /api/nslcm/v1/ns/sfcs/{instId}
cancel VNF list
- get vnf inst list array from NFVO_NFINST
  - for each vnf inst
    - delete_vnf (nf_instid)
      - POST /api/nslcm/v1/ns/terminateVnf/{instId}
cancel VL list
- get VL Inst array
- for each VL inst
  - DELETE /api/nslcm/v1/ns/vls/{instId}
cancel PNF list
- get pnf inst array
- for each pnf inst
  - DELETE /api/nslcm/v1/pnfs/{instId}
modify the ns_inst_id row state from the NFVO_NSINST database table
modify NFVO_NSINST status = NOT_INSTANTIATED
set job status = NS terminate ends
Update NsLcmOpOCC to COMPLETED
Send nsLcmOperationOccurrenceNotification

attribute name	data type	cardinality	description
nsdIds	Identifier	0..N	If present, match NS instances that were created based on an NSD identified by one of the nsdId values listed in this attribute. See note 1.
vnfdIds	Identifier	0..N	If present, match NS instances that contain VNF instances that were created based on a VNFD identified by one of the vnfdId values listed in this attribute. See note 1.
pnfdIds	Identifier	0..N	If present, match NS instances that contain PNFs that are represented by a PNFD identified by one of the pnfdId values listed in this attribute. See note 1.
nsInstanceId	Identifier	0..N	If present, match NS instances with an instance identifier listed in this attribute. See note 2.
nsInstanceNames	String	0..N	If present, match NS instances with an NS Instance Name listed in this attribute. See note 2.
NOTE 1: The attributes "nsdIds", "vnfdIds" and "pnfdIds" are alternatives to reference to NS instances that are created based on certain NSDs, or contain VNF instances that are based on certain VNFDs, or contain PNFs that are based on certain PNFDs in a filter. They should not be used together in the same filter instance, but one alternative should be chosen. NOTE 2: The attributes "nsInstanceIds" and "nsInstanceNames" are alternatives to reference to particular NS Instances in a filter. They should not be used both in the same filter instance, but one alternative should be chosen.
