The Routing Area Yang Architecture design team

Charter

Announcement

With the increase of YANG models, it is desirable to have an architecture that can suggest and articulate common functionality to be used by multiple models and how the models interconnect. Some individual work has been done in this space and the design team is encouraged to consider such input. Although this is a concern across the entire scope of YANG models, this design team is focused on the question of providing an architecture for the protocols and functionality contained inside the Routing Area. This may identify additional desirable models and common functionality; those suggestions can be raised in Netmod.

Common conventions and use of YANG functionality in similar ways can help make the interactions of models easier to understand. RFC 6087 provides some guidance; an update is underway now in draft-ietf-netmod-rfc6087bis. If the design team has recommendations for how the models should be written, those which are not routing-specific can be written down and discussed in netmod as part of a planned update of RFC 6087.

It is also important to consider how future extensibility and features in Routing Area work will need to be captured in YANG models. While the IETF is busy developing YANG models, we are still working on new routing area features and technology. The design team should publish and maintain best current practices for how new features can easily augment existing YANG models so that authors of those new features and technologies can understand how to consider YANG modeling in their manageability considerations.

This design team will write one or more internet-drafts describing the proposed architecture of the models, the recommended common conventions, and considerations for how to model new features. The architecture is the highest priority. The design team will address all the aspects of the routing area modeling: from configuration, to operational state, notifications, and RPCs. This design team will regularly coordinate with the YANG doctors for review and advice. These drafts will be discussed in RTGWG. It is possible that some of the content, such as the details of the architecture, will go to a wiki to be updated while other content, such as advice for extensions and common conventions, would be published by IETF consensus.
