[ptpd - Help] Questions on products and licensing

[Daniel Le]

Thank you, John and Gertjan's response on a separate email reply.

 

I found Meinberg, Symmetricom, Time & Frequency Solutions, and a few
other vendors, however none provides support for IPv6 as of today.

 

IXXAC sells commercial implementation. I will check the latest Linux
kernel. My 2.6.35.7 kernel doesn't have PTP and I intend to make use of
FPGA hardware assisted timestamping.

There are numerous vendors for the HW, you'll just need to look around
on the web for what you specifically need. 

 

There is no such thing as a commercial version of IEEE 1588 available.
The latest upstream kernel has support for it already and there is a new
daemon which goes along with the kernel implementation.  You can find
all you need about this on either the LKML or net-dev mail lists.  Look
for the on the kernel.org web site.

 

As for the licensing goes, it would depend on exactly what you are doing
with it.  If you are just using the Linux kernel I don't think there is
a problem (I'm not a lawyer btw) but if you are going to make some sort
of HW implementation then you may need to license things.  There are I
think 4 patents around this technology I believe.  They are called out
at the end of the actual IEEE specification.

 

Cheers,

John

Hello,

 

I'm looking at IEEE 1588-2008 implementation and would really appreciate
recommendations on:

 

- Vendors of PTPv2 grandmaster product that supports IPv6.

- Commercial version of IEEE 1588-2008 protocol software for integration
with Linux (besides the ptpd open source code).

 

And are there license/royalty fees for deploying IEEE 1588 patents and
algorithms (independent to the code)?

 

Thanks,

Daniel
