White Paper Abstract:
This paper is intends to primarily give a glimpse into why this is such a complex subject, why the Network Time Protocol (NTP), which is so pervasive and commonly used everywhere in IP networks and systems today, cannot solve this issue alone, and what else you may be able to do to help address the problem.f you could query every device in the network instantaneously and ask what the time of day each device thinks it is, they will generally answer back much like any computer and will report some differences between all the devices ranging from many seconds to a minute or more, even on a network operating well.why is this so difficult, you ask? Due to time itself: the time it takes to get time and the delay and jitter involved in the transfer of time over the IP Network. It is an elusive subject and once we attempt to dig deeper and uncover the underlying concepts of Time Accuracy and Clock Synchronization, what originally seemed like a casual little issue of a few seconds, now turns into a Grand Canyon size issue of 100's of milliseconds and 1000's of microseconds
