Re: [Linuxptp-users] List of Boundary clocks

Thank you for the reply.

Actually I am going to design a network to run the PTP protocol(with BC).
But the main problem for me is I don't access to real hardware. I though
maybe using a PC with several network card (HW time stamping) would help.
But, share clock is another problem!!!

Now, I am thinking of possibility to use of virtual switch, router and NIC
.. Is anyone have experience of it?? Is it possible?

BR,
Mozhdeh
