NFV Management and orchestration

I have a doubt about how should be a basic workflow of creation of VM, VNF and then model a device and a service.

With NCS I create:

  • the device model (NED) and sync it with the device configuration
  • the service model (for example vLAN or VPN)

But that suppose I already have the devices.

But If I want to be also the administrator of the NFVI?

Does the orchestrator have the capability to interact directly to a VIM in order to create virtual device?

Should  NCS (as orchestrator) interface directly with a VIM to ask the creation of a VM

or NCS should interface to the VNF Manager (ESC)  and it will interface with the VIM?

Thanks

Eu

Hi Raffo,

The ESC talks to OpenStack using REST as far as I know.

ESC also contains a ConfD instance which provides for NETCONF communication between NCS and ESC.

However, these are ESC internals.


I don't have a flow diagram to share with you right now.

However, you can run the example and examine ncs-java-vm.log and correspond it to the code. I guess it would give you some idea about interaction between NCS and ESC.


Thanks,
