Continuous testing is essential to get predictable infrastructure performance

With MiFID II set for January 3, 2018 the financial industry is currently trying to meet the clock synchronization UTC divergence. MiFID II will introduce the requirement for trading venues, their members and participants to synchronize the business clocks used to record the date and time of reportable events to UTC with an accuracy of 100 microseconds. How to best achieve this accuracy, monitor and demonstrate compliance, with a robust and competitive implementation is a major challenge facing the global financial sector.

Our solution


The LANTIME M1000, equipped with the new generation of the Meinberg time stamping unit HPS (High Precision Synchronization) provides a future-proof platform for your IEEE 1588 / NTP infrastructure.

90,000 NTP requests/second
The high-performance processing unit, the 1-step master clock and the 1GE interface with SFP slot support a very large number of PTP clients. Thousands of IEEE 1588 slave devices or NTP clients can be synchronized, both in IPv4 and IPv6 networks, for example transaction servers running high-frequency trading applications. For NTP-based synchronization, each of the HPS-100 network interfaces of the LANTIME M1000 can be configured to act as a carrier grade NTP server with 10 ns time stamp accuracy, serving up to 12,000 NTP requests per second on each port. Each HPS module can serve time to up to 2,048 PTP Slaves at full Unicast rate (128 sync/128 delay req. per second) or 250K DelayRequests per second in Enterprise Profile/Hybrid mode.

This concept ensures future-proofness and expandability by allowing to add or replace modules when new technologies or interfaces are required and makes this product one of the most scalable and flexible synchronization solutions on the market.

NTP vs PTP: Network Timing Smackdown!
Five Minute Facts About Packet Timing by Doug Arnold

"I get asked a lot of questions from customers about network timing technology. Some of them are challenging to answer. However, one that I get all the time that is easy to answer is this: “Do I want NTP or PTP?” It all comes down to accuracy. I simply ask them what time transfer accuracy do they need. Guilty, I’m answering a question with a question. Let me put it this way: Is the accuracy you need measured in microseconds or nanoseconds? If the answer is yes, you want PTP (IEEE 1588). If the answer is in milliseconds or seconds, then you want NTP."

Recommended Firmware Update for Meinberg LANTIME Systems

Bug Fix

Meinberg Technical Support issued a warning that LANTIME firmware versions 6.18.001 to 6.20.013 are affected by a critical software bug that could result in the device becoming unresponsive.

This only affects customers who are using the LANTIME NTPMon functionality to monitor the offset of remote NTP clients. All devices which are not configured to monitor NTP clients will not be affected. If your LANTIME devices use one of the mentioned firmware versions and you are using Meinberg’s NTPMon feature to monitor at least one NTP node, please contact Meinberg technical support (techsupport@meinberg.de) for further assistance as soon as possible. Meinberg support engineers will together with you determine if your device is really affected by the software bug and will assist you with applying the necessary fix.
