Master timing facilities, Precise time protocols
The XLi IEEE 1588 Grandmaster Clock with GPS (Global Positioning System) reference supports the new Precise Time Protocol (PTP) version 2 protocol that enables accurate synchronization over Ethernet LANs, offers users the ability to synchronize clocks within better than one hundred nanoseconds accuracy using only a network connection.
With the recent ratification of the IEEE 1588-2008 protocol specification — also known as Precision Time Protocol (PTP) Version 2 — distribution of precise time and frequency over Ethernet network infrastructures enters a new phase.
By replacing costly TDM backhaul lines with Ethernet, service providers can reduce recurring backhaul line costs by up to 90% while simultaneously boosting network capacity for bandwidth hungry applications like text messaging, music downloads and video streaming.
Until now, many network service providers have been reluctant to transition from TDM to Ethernet backhaul due to Ethernet’s inherent lack of an adequate timing and synchronization mechanism. However, with the advent of IEEE 1588-2008, providing precise timing and synchronization over Ethernet is no longer an issue.
IEEE 1588-2008 has now been adapted to meet the more sophisticated synchronization requirements of telecommunications applications. It 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. Some of these capabilities, like frequency synchronization and multicast support, are explicitly supported within the IEEE 1588-2008 framework while other capabilities, such as support of unicast and telecom profile extensions, provide the higher level of accuracy and performance optimization that telecom requires.
As service providers begin to deploy IEEE 1588-2008, they need to understand how these different capabilities, or lack of them, may impact their network performance and service level agreements. Optimal results can be achieved if they can anticipate future requirements and choose a carrier class PTP solution that offers the highest level of resiliency, performance, scalability and management.
