[Med] We hope this can be by software if we want to benefit from the automation in the full cycle but the approach still apply independently how a service request is captured. We don't zoom that much on that interface because the document is more on the provider's side. So what protocol is involved, and which entity on the > customer side is doing it? [Med] The component at the client side are generally represented as service ordering (see RFC 4176). That component may interact with the Order Handling at the provider side using a variety of means such as https://www.rfc-editor.org/authors/rfc8921.txt (Section 5) or by offering a management interface to the customer, etc. Please let us know if you think that we need to add some text on this part. > > > 5.3.

[Med] Point taken. We will also clarify that in some cases the use of YANG does not require NETCONF/RESTCONF. > > Regards > Brian Carpenter _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
