Re: Coordinated time efforts
While there is already some coordination between LinuxPTP and PTPd, this also happens with all of the projects. Shortly after joining, we were all chatting about how to get the best time measurements thru the network stack. Julien Ridoux and Matt Davis of the RADclock project told me "We tested all of the ways to do this, and found the PCAP library to be the best way to go." I took this information and sent it to Richard Cochran and George Neville-Neil, and shortly thereafter, it was in PTPd. We're looking at using this for NTP as well.
LinuxPTP and PTPd serve different customer bases, and they also have different licenses. LinuxPTP wants to be the best possible PTP implementation for the latest Linux kernel. It's not designed to run on older linux kernels, and it's not designed to run anywhere else. PTPd is designed to be portable, and as good as possible. LinuxPTP uses the (Open Source) GNU Public License, and that is a "win" for some and a "lose" for others. PTPd uses the (Open Source) BSD license, and that's a "win" for some and a "lose" for others. Neither project wants to change their license, and that's perfeclty OK. We all still talk to each other, and can leverage off the collaboration. Membership in NTF's PTP Consortium helps both LinuxPTP and PTPd.
