The Broadband Forum has released TR-355, YANG Modules for FTTdp Management. The specification set covers the configuration and control of distribution point units (DPUs) in a G.fast fiber to the distribution point (FTTdp) architecture.
TR-355 consists of seven YANG data model software specifications. These include common Broadband Forum YANG types, an interface object supporting xDSL and G.fast, and the ITU‑T standardized objects for start up of G.fast or VDSL, G.fast and VDSL2 configuration, status monitoring, performance management, testing and diagnostics, and Single-Ended Line Test (SELT) and Metallic Line Test (MELT) configuration and test results. The modules are publicly available via GitHub.
The Broadband Forum asserts the FTTdp management model is the first deliverable written in the YANG modelling language, which is commonly used in software-defined networking (SDN) development environments. It also is the first to follow the Forum's new Intellectual Property (IP) Policy, which has been updated to streamline software licensing.
"While the Broadband Forum has been delivering TR-069 software for Residential Gateway management and configuration for more than 10 years, TR-355 breaks new ground for the Forum in that it is the first specification to publish YANG modules and deliver software specifically designed and licensed for wide scale and rapid adoption by the networking industry," said BT's Kevin Foster, chairman of the Broadband Forum.
"This pioneering software-driven deliverable will enable operators to manage standardized FTTdp network elements from multiple vendors, giving more choice and flexibility as ultrafast networks are built out. It will also reduce the integration complexity of adding new network elements as networks scale and evolve to meet demanding customer requirements for advanced, assured and ultrafast broadband services," Foster added.
