IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas
  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

PTP - Precision TIME Protocol

A new request from a financial market require to us the PTP: https://en.wikipedia.org/wiki/Precision_Time_Protocol

Could you add it on IBM I?


Use Case:

The financial market require to us for the new release this standard.

    This RFE has been in "Needs more information" for over a year with no information provided, so it is being closed.

    Do you still have a requirement for PTP-based time synchronization on IBM i. If yes, is delivery in the next IBM i release satisfactory?

    What is your expectation of clock synchronization tolerance in microseconds?

    Given the following definitions, is it sufficient that IBM i LPAR acts as a slave device in the PTP network.
    Slave device - A system running the ptpd daemon that accepts commands from a master device and synchronizes its system time to match the associated boundary clock time.
    Master device - A device bound to a boundary clock that synchronizes time with a set of one or more PTP slave devices on the same network.
    Grandmaster device - A master device that has the best clock provided by the Best Master Clock algorithm. It synchronizes all of the other master devices (also known as the boundary clocks), which in turn update and synchronize all of the associated slave devices. The grandmaster clock is also known as best master clock or best clock.

    If IBM i supported PTPD similar to AIX (https://www.ibm.com/support/knowledgecenter/ssw_aix_72/p_commands/ptpd.html) are there any must-have options?

    Any guidance on the expected PTP network topology and vendors would be most welcome.

    Have you tried installing a copy of the ptpd from AIX into the PASE environment?
