Dear all,

 

The IETF TEAS and CCAMP working groups would like to thank the ETSI ISG NFV for notifying the start of the work on multi-site connectivity services. We acknowledge the commonalities between the WIM infrastructure manager interfaces and the ACTN ones, in particular the CMI (CNC-MDSC) interface. Our understanding is that the scope of the WIM interfaces is not limited to the management of the underlay Traffic Engineered infrastructure but also the connectivity services that can be built on top of that, like e.g. L3VPNs and L2VPNs.

 

The relevant documents specifying YANG models (and related status) for the connectivity services are:

*	L3SM – A service model for L3VPN services – RFC 8299
*	L2SM – A service model for L2VPN service – RFC 8466
*	L1CSM -  <https://datatracker.ietf.org/doc/draft-ietf-ccamp-l1csm-yang/> https://datatracker.ietf.org/doc/draft-ietf-ccamp-l1csm-yang/  stable working group document already reviewed by YANG doctors.
*	L3NM –  <https://datatracker.ietf.org/doc/draft-ietf-opsawg-l3sm-l3nm/> https://datatracker.ietf.org/doc/draft-ietf-opsawg-l3sm-l3nm/  stable working group document

 

On the other side ACTN provides guidelines for the implementation of interfaces for the management of traffic engineered underlay infrastructure (https://datatracker.ietf.org/doc/draft-ietf-teas-actn-yang/). A wide variety of YANG models can be used to implement various features (e.g. calendaring, telemetry) but a minimal set of mandatory models to operate the network is identified:

 

*	TE topology:  <https://datatracker.ietf.org/doc/draft-ietf-teas-yang-te-topo/> https://datatracker.ietf.org/doc/draft-ietf-teas-yang-te-topo/ – approved by the IESG and in the editor queue
*	ACTN virtual network:  <https://datatracker.ietf.org/doc/draft-ietf-teas-actn-vn-yang/> https://datatracker.ietf.org/doc/draft-ietf-teas-actn-vn-yang/ – stable working group document
*	TE tunnel:  <https://datatracker.ietf.org/doc/draft-ietf-teas-yang-te/> https://datatracker.ietf.org/doc/draft-ietf-teas-yang-te/ – stable working group document

 

Extensions to these models are defined in the CCAMP working group to provide technology specific extensions. TE Topology and TE tunnels augmentations are being defined for WSON (Wavelength Switched Optical Networks), flexi-grid WSON, OTN (digital layer of the Optical Transport Network).

In the eventuality in which the ETSI NFV ISG identifies additional requirements that are not currently addressed in the ACTN framework (RFC8453) and models, they can be proposed as individual contributions either in the TEAS working group (if technology agnostic) or in the CCAMP working group (if technology specific) and follow the IETF process.

Lou Berger & Vishnu Pavan Beeram (TEAS chairs)
