Applicability of YANG models for Abstraction and Control of Traffic
Engineered Networks
draft-ietf-teas-actn-yang-07
Abstract
Abstraction and Control of TE Networks (ACTN) refers to the set of
virtual network operations needed to orchestrate, control and manage
large-scale multi-domain TE networks, so as to facilitate network
programmability, automation, efficient resource sharing, and end-to-
end virtual service aware connectivity and network function
virtualization services.
This document explains how the different types of YANG models
defined in the Operations and Management Area and in the Routing
Area are applicable to the ACTN framework. This document also shows
how the ACTN architecture can be satisfied using classes of data
model that have already been defined, and discusses the
applicability of specific data models that are under development. It
also highlights where new data models may need to be developed.
