[ptpd - Help] Questions on products and licensing

[Ronciak, John]

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
