Five Minute Facts About Packet Timing By Doug Arnold and Andreja Jarc A previous post discussed unicast PTP. Most PTP Profiles are based on multicast communication. However, PTP can operate using unicast. This is necessary in networks which … [Continue reading]
Five Minute Facts About Packet Timing By Doug Arnold. Quiet! Such is the lament of a PTP slave in a delay request - delay response PTP network. A slave port needs to receive Sync and Announce messages from a master port, and it needs to send … [Continue reading]
By Heiko Gerstung. We receive an ever increasing number of questions from our customers regarding MiFID 2 and the time synchronzation of RTS 25 and therefore decided to publish the answers here in one place: 1. What is MiFID 2 ? The … [Continue reading]
Heiko Gerstung is Managing Director of Meinberg and joined the company in 2004 as a software engineer. He has decades of experience with GNU Linux and during his university time touched other Unix flavors like Solaris and AIX. In addition to his … [Continue reading]
By Andreja Jarc. In a previous post I introduced tests with different IEEE 1588 / PTPv2 configurations where the PTP accuracy of the slave device was measured for each test case. The test cases performed were as follows: A direct link … [Continue reading]
Last month two Chinese researchers gave a presentation titled "Time is on my Side" during the "Hack in The Box" 2016 SecConf event in Amsterdam, NL (https://conference.hitb.org/hitbsecconf2016ams/) . In this presentation, the researchers outlined a … [Continue reading]
Five Minute Facts About Packet Timing By Doug Arnold. In an earlier post I described how boundary clocks and transparent clocks correct for timing errors in the network between the PTP grandmaster and PTP slaves. But what do you do if you don't … [Continue reading]
By Andreja Jarc. This time I prepared some experiments with different IEEE 1588 / PTPv2 configurations where the accuracy of the end device was measured for each test case. In all Test cases a Meinberg M500 IMS (modular platform in a railmount … [Continue reading]
By Andreja Jarc. Synchronized timing is vitally important when many systems work together in a network. Services such as Logfiles, Correlation of Events, User Authentication Mechanisms, Job Scheduling e.g. for backups or Active Directories … [Continue reading]
Five Minute Facts About Packet Timing By Doug Arnold. A while back I posted about the Telecom Profile for Frequency Synchronization, or ITU-T G.8265. In the view of the International Telecommunications Union (ITU), frequency was all they could … [Continue reading]
