[CCAMP] Summary of Microwave Topology Yang work at IETF 116

[Scott Mansfield <[e-mail]>]

There are three drafts for consideration at IETF 116 related to the on-going Microwave Topology Yang work.  This short email provides a summary of the recent work.



At IETF 115 and based on comments from the CCAMP community and YANG experts, it was suggested to split the three yang modules described in https://datatracker.ietf.org/doc/html/draft-ietf-ccamp-mw-topo-yang-04 (the previous draft from October 2022) into separate internet drafts.  Augmenting topologies with bandwidth availability or pointing to interfaces from topology nodes is independent of Microwave Topology.  Separating the bandwidth availability topology yang and the interface topology yang from the microwave topology yang work was agreed.  It is important to note that the microwave topology yang work can proceed independently.



Pointers to the latest version of the internet drafts:

Microwave Topology Yang:

https://datatracker.ietf.org/doc/html/draft-ietf-ccamp-mw-topo-yang
Provides augmentations to the IETF’s TE-Topology work to support Microwave/Millimeter wave nodes.

Bandwidth Availability Yang:

https://github.com/ietf-ccamp-wg/draft-ietf-ccamp-bwa-topo-yang
There is a desire to support sharing bandwidth availability information for nodes in a topology.  This is useful for Microwave, but independent of microwave, so this capability was split out as a separate YANG module that augments TE-Topology.

Interface Reference Yang:

https://github.com/ietf-ccamp-wg/draft-ietf-ccamp-if-ref-topo-yang

Provides the ability to reference termination points in a TE-Topology to their associated IETF Interface.  This is useful to provide a way to trace from the topology node to the interface used.  This feature augments TE-Topology and is useful for other topologies.
