Previous IETF Blog posts have provided updates on features and tools that have been incorporated into and inspired by the YANG Catalog. Tools available at the YANG Catalog website allow you search for YANG modules, display their metadata, and analyze their impact via a graph visualization.
As just one example of the practical benefits these tools provide, in 2016, the Broadband Forum published its first YANG models for Fiber-To-The-distribution point (FTTdp) management software specification, which allowed operators to configure and control fiber-fed nodes (DPUs) in the periphery of the access network, enabling interoperability for FTTdp management. In 2017, Broadband Forum Chairman Kevin Foster stated, “By providing open access to a wide variety of models that can be combined to meet specific network management needs, including active validation and testing of the new models, the YANG Catalog provides an alternative to large and sometimes cumbersome standards processes. It is a key enabler in the evolution towards more agile and programmable networks.”
The YANG Catalog’s ongoing development has been possible thanks to the contributions of many individuals, and the funding support of Cisco. Befitting the broad participation and use the YANG Catalog now enjoys, the IETF Administration LLC has taken over its ongoing support. This move doesn’t change our commitment to the project; as individuals we look forward to continuing to be personally involved in the further development of the YANG Catalog. We also expect participation and use across the industry to continue to grow.
