If you are excited to explore YANG models dependencies using this
tool, give it a try with the YANG modules you’re most impatient to see
So what are the hot topics for this IETF 97? We continue to add flexibility to support finalization of modeling work.
First the schema mount draft,
which specifies a mechanism to combine YANG modules into the schema
defined in other YANG modules, is an essential building block that
should be standardized soon. Many YANG modules depend on this schema
Second, the Revised Conceptual Model for YANG Datastores draft
will receive a lot of attention during this week. It focuses on a
revised conceptual model of datastores based on the experience gained
with the current model and addresses requirements that were not well
supported in the initial model. Basically, it introduces new datastores,
for accessing additional views of the intended configuration, and a new
ability to obtain the operational state.
Third, focusing on finishing up key YANG models, such as key chain,
key store, topologies, key routing ones (OSPF, ISIS, PIM, BGP),
access-list, logical network elements, etc. The routing base models
follow the config and config-state branch conventions for specifying,
respectively the configuration and operational data. Models being
submitted for publication request should follow this same convention. We
know that operators are moving to data modeling-driven management, and
waiting for standard models.
As mentioned during the last IETF meeting in Berlin, it’s important
to publish the IETF YANG models within a reasonable time frame, if the
IETF wants to play a key role in specifying YANG models, as opposed to
only standardizing the protocols (NETCONF/RESTCONF and related push
mechanisms) and related encodings (JSON, XML). As I mentioned in Berlin 3
months, we have maximum a year to publish the majority of those IETF
YANG models. It’s time to focus and deliver.
More on the Hackathon outcomes later after the IETF, but I can
already tell that this Hackathon brought new tools and implementations.
This is essential as your automation is as good as your tools chain.
After the IETF 97, I plan on updating this blog with the latest achievements.
