Hi Dan,



Thanks for the heads up.



Just a few comments from my side:



  1.  Is there a related "non technology specific" work ongoing in e.g. TEAS? I couldn't find it. I was expecting as usual to see a generic work and then the optical extensions in CCAMP, but I don't have any objection if you want to apply it to optical networks only.
  2.  Does FGNM exist as term also outside the context of ACTN or is something new that you're defining here only for ACTN and more specifically only for ACTN optical networks?
  3.  Figure 1 in my opinion should be provided as example and not made prescriptive. The OSS might connect to the MDSC, not necessarily to the domain controller. Moreover it could connect to different components for different purposes. Maybe what you could do is to have an OSS container sitting on top of the entire hierarchy with a box inside it called e.g. OSS-FCAPS that connects to the domain controller. This allows representing what you're targeting, without implying any architectural obligation.



...while further reading the draft I think I found myself the answer to question 1...i'll paste it here for who might have the same question:



This can make generalisation of configuration

   and management hard, and means that the nature of ACTN FGNM is

   different in an optical network than it might be in a more general

   (and specifically, packet-based) TE network.





Cheers

Daniele

Morning CCAMP'rs,



We have made good progress on Fine-Grain Network Management (FGNM) for optical networks using the ACTN architecture.



Please use this link for the changes since 01/02 and 03: https://shorturl.at/mEGJ4



Substantive updates include:



- Tightening the scope and intention of FGNM

- Updating the interface architecture between FGNM and ACTN

- Highlighting mechanisms to extract optical resource information

- Discussing the role of the ACTN MPI interface

- Linking the I-D to recent work proposed by Chaode (https://datatracker.ietf.org/doc/draft-yu-ccamp-te-fgnm-yang/)

- Adding Manageability Considerations and expanding Security Considerations

- New co-author (Choade)

- Thanks to Daniele and Victor for previous feedback on the I-D



We would appreciate further review and thoughts on the proposal from the working group.



BR, Dan.

Title:    Integrating YANG Configuration and Management into an Abstraction and Control of TE Networks (ACTN) System for Optical Networks

Abstract:



   Many network technologies are operated as Traffic Engineered (TE)

   networks.  Optical networks are a particular case, and have complex

   technology-specific details.



   Abstraction and Control of TE Networks (ACTN) is a management

   architecture that abstracts TE network resources to provide a limited

   network view for customers to request and self-manage connectivity

   services.  It also provides functional components to orchestrate and

   operate the network.



   Management of legacy optical networks is often provided via Fault,

   Configuration, Accounting, Performance, and Security (known as FCAPS)

   using mechanisms such as the Multi-Technology Operations System

   Interface (MTOSI) and the Common Object Request Broker Architecture

   (CORBA).  FCAPS can form a critical part of configuration management

   and service assurance for network operations.  However, the ACTN

   architecture as described in RFC 8453 does not include consideration

   of FCAPS.



   This document enhances the ACTN architecture as applied to optical

   networks by introducing support for FCAPS.  It considers which

   elements of existing IETF YANG work can be used to solve existing

   scenarios and emerging technologies, and what new work may be needed.

   In doing so, this document adds fine-grained network management to

   the ACTN architecture.  This enhanced architecture may then be used

   to evolve networks from CORBA and MTOSI FCAPS interfaces to IETF-

   based YANG and RESTful API capabilities.
