//////////////////////////////////////////////////////////////////// FEATURE:
implementation of the access node. This
enables operators to make additional
adaptation of access nodes to meet their
individual network needs, while providing
them with examples of common functions
that operators are likely to perform when
automating and managing their networks.
Not only does this allow adaptation to
certain specifics of a vendor’s access
network model, it also supports access
nodes that use protocols other than
NETCONF/YANG. This fosters the growth
of a wide and interoperable ecosystem of
solutions with great benefit for operators’
adoption and maintenance.
the NBI data models enable automated
access inventory, service provisioning
and monitoring, as well as network
commissioning functionalities. Operators are
also given the ability to manage the library
of YANG modules suitable for various access
node types, such as an Optical Line Terminal
(OLT), Optical Network Terminal (ONT) or
Distribution Point Unit (DPU). Additionally,
the portfolio of NETCONF commands are
also available to operators, which can be
applied to access nodes (OLTs, DPUs, ONTs)
for the configuration of network interfaces,
traffic forwarding rules and traffic descriptors
and associated filters.
The end result
As part of this, operators can access a new
set of YANG models for the NBI which
provides the aggregate description of
underlying access network assets that are
made up of specialised PNFs and VNFs.

While Release 1 of OB-BAA enabled operator
migration to cloud-based deployments,
Release 2 aims to do this faster and with
greater ease – opening the door for
operators to achieve dramatically simplified
DIGITAL TRANSFORMATION
service provisioning and faster time-to-
market of new cloud-based access services.
Overall, OB-BAA will make it possible for
operators to migrate to and manage
programmable network environments,
where new services can be deployed rapidly
through interaction with the common
abstraction of access nodes. Operators and
equipment manufacturers will be able to
reap the benefits of greater networking
flexibility and be able to streamline
development by implementing standard
interfaces, while differentiating their service
offering via stable standardised platforms.
Facilitating an agile, flexible and integrated
approach, OB-BAA allows service providers
to embrace the best of open source and
open standards, creating a programmable
broadband network which delivers on the
promise of next-generation broadband,
while reducing service providers’ costs and
protecting their investments. n
