PRECISION TIME PROTOCOL (PTP)


How PTP works

An introduction to Precision Time Protocol (PTP). The role PTP has in transporting a clock from a core location across an entire network is introduced. The standards that apply to this vital network technology are also introduced.

How to test PTP

What test requirements are there for the Precision Time Protocol? What test methodology and parameters need to be considered, and how is the functionality verified? The crucial roles of accuracy and repeatability are discussed.

What is gPTP?

The fundamental building block on which Time Sensitive Networks are constructed is the time distribution layer. In most cases this is provided using the generalized Precision Time Protocol (gPTP) defined in IEEE Standard 802.1AS.

Time Transfer in Industrial Ethernet Applications

One of the most prevalent protocols for industrial time transfer is Precision Time Protocol (PTP). PTP offers dependable, high-accuracy time synchronization of multiple clocks over Ethernet networks enabling real-time systems and applications.

How SyncE works

An introduction to Synchronous Ethernet (SyncE). The role SyncE has in transporting a clock from a core location across an entire network is introduced. The standards that apply to this vital network technology are also introduced.

Five Steps to deploy PTP for LTE

A strategy for synchronisation in LTE networks. Topics include Sync needs along with ITU-T models, network readiness, sync service level agreements via lab tests, ITU network models and PTP performance at demarcation points.
