IEEE 1588 PTP Solutions

 

IEEE 1588 Precision Time Protocol (PTP) is rapidly overtaking TDM, NTP and IRIG as the synchronization technology of choice for telecom, computer network and instrumentation applications respectively. Combining the low cost and huge user base of Ethernet with the precision of hardware time stamping, IEEE 1588 offers dramatic return on investment for users fluent in the protocol’s technical principles and best deployment practices. Learn how to incorporate this emerging standard into a total timing strategy optimized to meet your needs.

Packet-Based Primary Reference Source for Synchronizing Next Generation Networks (IEEE)

Responding to consumer demand, service providers are expanding and upgrading their telecommunications networks at a phenomenal pace. As these networks grow they also need to ensure the non-stop availability of their timing and frequency synchronization reference, commonly known as a "Primary Reference Source" (PRS) to maintain Quality of Service (QoS), avoid dropped calls, support video streaming services, and enable LBS applications such as 911 calls. Carriers migrating to packet-based transport, however, lose ubiquitous access to the legacy TDM reference inputs. There is therefore a compelling need for a stable, cost-effective, and robust packet PRS that will provide synchronization for packet networks.

Best Practices in IEEE 1588-PTP Network Deployment

IEEE 1588 (also known as Precision Time Protocol or PTP) is specifically designed to provide precise timing and synchronization over packet-based Ethernet infrastructures. With the advent of IEEE 1588-2008 (version 2), PTP has now been adapted to meet the more sophisticated synchronization requirements of telecommunications applications. IEEE 1588-2008 captures those requirements by providing a set of added capabilities and protocol extensions that allow service providers to fine tune their packet-based networks for the stringent timing and synchronization requirements of telecom-oriented applications. However, optimal results can be achieved only if service providers anticipate future requirements and choose a carrier-class PTP solution that offers the highest level of resiliency, performance, scalability and management.

Synchronizing IP Mobile Networks

As mobile operators need to transport more data for less money, TDM transport becomes less viable. IP/Carrier Ethernet overcomes the economic and capacity limitations of TDM. However, IP requires QoS and synchronization to be consciously engineered into the solution. This paper addresses the business challenges of moving to IP/Carrier Ethernet and explores the alternatives for deploying sync delivery mechanisms such as SyncE, IEEE 1588 (PTP) and GPS. This practical guide to selecting a synchronization strategy for Long Term Evolution (LTE) systems provides a clear, in-depth look at defining IP related sync objectives, assessing multiple sync technologies and understanding topics such as on-path support.

Measuring PTP SW Slave Accuracy

This paper describer how to enable a computer to accurately measure the performance of a local clock steered by an IEEE PTP software slave or NTP client. It reviews the synchronization problem and presents procedures for test setup, calibration and clock measurement. The results show that clock accuracy may not be as good as one might think, due to factors related to asymmetric path delays and scheduling. Methods to improve clock accuracy using a PTP slave are also discussed.
