<p class="MsoNormal"><span style="color:#1F497D">There are numerous vendors for the HW, you’ll just need to look around on the web for what you specifically need.

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">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.<o:p></o:p></span></p>

<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'm looking at IEEE 1588-2008 implementation and would really appreciate recommendations on:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">- Vendors of PTPv2 grandmaster product that supports IPv6.<o:p></o:p></p>
<p class="MsoNormal">- Commercial version of IEEE 1588-2008 protocol software for integration with Linux (besides the ptpd open source code).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And are there license/royalty fees for deploying IEEE 1588 patents and algorithms (independent to the code)?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
