Open Online YANG repository enhances network management

Collaboration among network engineers active in the Internet Engineering Task Force (IETF) and the Broadband Forum has produced the YANG Catalog, an open online repository designed to make sharing, finding and using network management models simpler and easier, the companies said.

The YANG Catalog collects models specified for use in a wide variety of networking equipment and deployed by operators around the world to accelerate and automate network operations and management.

The catalog contains numerous models standardized in the IETF, Broadband Forum and IEEE, as well as vendor-specific data models. The catalog makes it easy to search for models and identify their maturity level, module type and implementation information.

Developed by the IETF, YANG is a data modeling language, widely used by network operators to automate the configuration and control of network elements.

As a common language, YANG enables the reuse of data models across equipment from different vendors and networks managed by different operators. The YANG Catalog was built by engineers from many different networking companies while participating in IETF Hackathon events.

The Broadband Forum published its first YANG models for Fiber-To-The-distribution point (FTTdp) management software specifications last year. The Forum´s work on TR-355 has delivered YANG Models for Fiber-To-The-distribution point management, allowing operators to configure and control fiber-fed nodes (DPUs) in the periphery of the access network, enabling interoperability for FTTdp management.

This management model was the first to follow the Forum´s new Intellectual Property Policy, which was updated last year to streamline software licensing and meet the increasing desire of industry players to develop specifications with agility and transparency.

While previously work in progress was only visible to Forum members, today the Forum is making its work in progress public so the industry can use the YANG models much more quickly and the Forum can perfect the models with industry feedback.

Broadband Forum, a non-profit industry organization, is focused on engineering smarter and faster broadband networks. Its work defines best practices for global networks, enables service and content delivery, establishes technology migration strategies, engineers critical device & service management tools, and is key to redefining broadband.

The IETF is the Internet´s premier technical standards body. It gathers a large open international community of network designers, engineers, operators, vendors, and researchers concerned with the evolution of the Internet architecture and the smooth operation of the Internet.
