DataMiner Precision Time Protocol (PTP) app

PTP (Precision Time Protocol) is the de facto protocol used by broadcasters, media network operators and service providers to synchronize device clocks in complex media networks to achieve accurately synchronized video, audio and meta-data streams.

PTP node provisioning, monitoring and performance management both for every single node and for the network on the whole are of key importance to maintain a robust, resilient and reliable clock distribution throughout the network over
time.

The DataMiner PTP app allows efficient 360° real-time monitoring of a PTP stack. It provides an overview of all PTP nodes and their roles, constantly monitors important PTP metrics and statistics of PTP devices, such as grandmaster clocks, boundary clocks and PTP slave devices, and allows you to identify any change in the PTP environment. You can also create multiple PTP domains, easily add PTP nodes to one of them and get separate monitoring views on the different domains.

More detailed information about the PTP app is available in the DataMiner Help.

Underlying technology: DataMiner Mediation

Based on the DataMiner Mediation functionality, any PTP-aware node can be added to the PTP appl easily. DataMiner Mediation maps vendor-specific PTP MIB files, API calls, naming conventions and metrics into an IEEE1588-2 compatible data model. This allows the PTP app to provide a uniform look and feel for the PTP environment, even if different vendors expose the same metric in different ways (e.g. with a different name, or with a different type of value).

Out-of-the-box deployment

The DataMiner PTP app:

  • Requires DataMiner version 10.0.3 or higher.
  • Comes with a deployment wizard that allows easy configuration of your PTP domain(s).
  • Includes a predefined set of alarm and trend templates that can be quickly adapted to a specific PTP environment.
  • Uses the DataMiner Connectivity Framework (DCF) to visualize how the PTP devices are connected. The DCF information can be specified manually or retrieve automatically using the IDP Solution.
