[ptpd - Help] Questions on products and licensing

Would you mind to share the advantages of the ptpd open source code from
your evaluation? Are there issues with Ixxat IEEE 1588-2008 protocol
stack?  I generally go with open source code, but this time I hesitate
because ptpd does not support IPv6 and there is no indication it will
soon. Commercial product also provides more support (at a cost).

 

WRT kernel 3.X, my embedded platform currently uses 2.6.35.7 and a
kernel upgrade is not quick job as it involves re-testing of all
applications and infrastructure code.

 

Regards,

Daniel

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
