We’ve seen some ‘interesting’ problems in deployed timing infrastructures. PTP Grandmasters that stop providing time on the network. Timing clients unable to determine that their timing source was completely wrong. Clients that are unable to fall back to another server, let alone another protocol. There really is a long list.
Failings of timing infrastructure are common, but understood. They can be avoided with some forethought, the right tools, and the…
You’ve just made a large investment in your timing infrastructure - great timing sources, a solid network to provide clean and accurate time to clients, and tools to get accurate, low overhead time sync where it’s needed. But how do you make sure you’re complying with OATS?
OATS specifies that your systems need to be within one second of NIST standard. But how do you do that? You’ve got a…
Timing accuracy is important, but so is the ability to retain that accuracy in the face of network outages and time source failures. TimeKeeper’s ability to track and seamlessly transition between multiple time sources regardless of protocol and device lets users define specific failover strategies to ensure they never lose accuracy. Also, by identifying the timing sources on the network, TimeKeeper can build a clear audit trail of clock behaviors…
Self-reported estimates of the accuracy of time synchronization software can be misleadingly incorrect. Here we detail how to independently test the accuracy of time synchronization and show the results. For platforms that rely on highly accurate time, trusting software-only log data without verification is a recipe for disaster - but by using the methods described here, users can avoid common misconceptions and pitfalls.
FSMLabs® TimeKeeper adds time synchronization support for Red Hat Enterprise Linux 6. This brings support for PTP, NTP, and external time sources with sub-microsecond precision directly to Red Hat applications.
FSMlabs® TimeKeeper is a plug-in solution that replaces OS-generated time with distributed time-keeping, locked to accurate reference sources. TimeKeeper helps IT managers distribute critical enterprise applications across clusters, data centers and wide-area networks, resulting in superior accuracy, increased performance and enhanced fault tolerance.
