    RP 2059-15, the Latest public Committee Draft (public CD)

    December 11, 2020

    WE WELCOME YOUR FEEDBACK!

    As the adoption of SMPTE ST 2110 systems continues to grow, the dependency on the SMPTE ST 2059 Precision Time Protocol profile defined by SMPTE increases too. This serves as the basis to provide reliable time transfer and synchronisation of all devices taking part in a ST 2110 system.

    The end-to-end monitoring of time and synchronisation is a key element contributing to successfully evaluate, commission, and operate those systems. The proliferation of PTP devices has led to diverse methods of reading the relevant timing related values. It being for a media node consuming time, a PTP aware network element distributing time or a PTP Grandmaster providing the timing reference. Furthermore, these different classes of devices each have their own specifics related to their operating role.

    Therefore, the monitoring of ST 2059 PTP across this diverse range of devices leads to a complex problem to be solved: How to provide a unified means to expose this data in a structured manner.

    The RP 2059-15 PTP Monitoring YANG Data Model creates such a framework. Born from a PTP YANG data model defined in the IETF for collecting such data, the model has been enhanced for SMPTE ST 2059 specifics and expanded to include additional monitoring capabilities, including Global Navigation Satellite Systems (GNSS) information used by PTP Grandmasters.

    The public Committee Draft has been published to the SMPTE GitHub repository for industry review, alongside a survey for collecting additional feedback related to the proposed data model defined by this project.

    If you are interested in the monitoring of PTP and associated systems, please https://github.com/SMPTE/rp2059-15 review the YANG Data model and Draft RP. And consider responding to the survey
