Yes but I was only pointing out the Linux project stuff.  Commercial versions have been around a long time.  The Linux one not really that long until now in the Linux kernel.

Since it is part of the kernel I'm assuming not.  I don't speak in any way for RH.  As of yet RH has not released a kernel based on a version that support PTP.  That will change as the next major release happen from them.  It will be based on a kernel that supports it.

Cheers,
John

John,

Not entirely sure what you mean.  Ixxat has had a commercial version for 5 years, see:

http://www.ixxat.com/ieee-1588-stack-v2_en.html

I evaluated it about 3 years and decided that the open source version had some advantages.


Re license - yes,  use of the 1588 protocol, regardless of the hard/software will always fall under the Lucent license - at least that is the understanding of the lawyers of the company I work for.  Cost are not prohibitive.

The kernel implementation came too late for us - I should dig into it some more. I seem to recall there was strong reluctance at Red Hat to distribute it due to the patents issues. Is this no longer true ?

Cheers

Gertjan
