IEEE 1588-2008 protocol, or Precision Time Protocol (PTP) has found it's implementation in different applications for time and frequency distribution through both local and IP-networks. PTP profiles standardized by different international organizations just for adopting PTP to a field existing network are analyzed and compared each other to see a trend of their mutual compatibility providing. Conclusions...
A conception of National time-scale distribution network, using PTP technology is considered in Ukraine as the most modern one and having large perspectives, since IEEE 1588 based applications are now expanded to be used in many different fields. Paper describes some PTP master-slave implementation results, obtained in a long-distance non-PTP network (rented VPN, Virtual Private Network was used)...
Networks timing information's 24×7 wander monitoring solution, actual both for Telecom synchronization networks and for IEEE1588 based networks, including optimally controlled PLL desing is described in this article. It also mentions a cost effective SDH or SyncE signals' probe unit design, expanded MTIE/TDEV metrics, and some monitoring experience with non- trivial results concerning GPS related...
