DataMiner Precision Time Protocol (PTP) app

Precision Time Protocol (PTP) is used by broadcasters, media network operators and service providers to deliver precise time to all slave devices in a PTP stack. PTP enables slaves locked to a PTP master to synchronize their clocks for any kind of media infrastructure. That includes SMPTE ST-2110 media and broadband access networks, DOCSIS 3.1 architectures and 4G/5G infrastructures.

Keep your PTP network service under control

The DataMiner Precision Time Protocol app collects and correlates data from each PTP device and interfaces with third-party PTP network analyzers to achieve a true 360° real-time PTP monitoring solution. The app immediately informs about network degradations or any PTP state changes, originating from GNSS (global navigation satellite system) down to every PTP slave device to ensure a stable and reliable PTP environment.

24/7 in-depth PTP monitoring
of every single PTP node over time

in-depth 24/7 PTP-centric monitoring of all PTP nodes in a PTP stack

interfaces with any PTP grandmaster (e.g. Meinberg M3000, Tektronix SPG8000, Evertz 5700MSC), PTP boundary clock (e.g. Cisco Nexus, Arista 7000-series), PTP transparent clock and PTP slave device, independent of protocol or vendor

integrates third-party PTP network analyzers (e.g. Tektronix Prism)

out-of-the-box deployment (installation wizard, comprehensive set of information and alarm templates) facilitates rapid deployment

easy navigation using multiple pre-configured tab pages to drill down to every single PTP metric and PTP statistics

monitor current grandmaster, its profile, configuration (e.g. BMCA values & PTP message rates) and performance (e.g. mean path delay, offset)

PTP topology viewer indicating the current grandmaster and most severe alarm of every PTP node including alarms related to the network links

track all PTP-related changes such as GNSS loss, grandmaster change, PTP port changes (master, slave, passive)

consolidated view on all PTP-related alarms from all PTP nodes

compare settings between multiple grandmasters or boundary clocks

track master, slave or passive state for each network interface on every boundary clock

track configured and actual PTP message rates on each PTP interface

track network degradations

monitor PTP behavior and performance over time, store historical PTP data

monitor PTP lock state and the reported grandmaster ID of each PTP slave node

force “master only” setting on boundary clocks to avoid slave devices not supporting “slave only” becoming a grandmaster

PRECISION TIME PROTOCOL

Complex underlying network architectures, PTP-aware switches, a vast number of PTP slave devices from multiple vendors and the best master clock algorithm (BMCA): this combination makes it a challenge to properly configure and maintain a stable and reliable PTP ecosystem. 24/7 in-depth PTP monitoring, keeping track of the PTP configuration, behavior and performance of every single PTP node over time has become a must.

And that’s exactly what the DataMiner Precision Time Protocol app enables you to do.

The DataMiner Precision Time Protocol app can be combined with DataMiner IDP (Infrastructure Discovery and Provisioning) to automatically detect and configure new PTP nodes and their connectivity (via LLDP) in the media network
