Irrespective of the physical communication paths, the PTP allocates logical
communication paths which you define by setting up PTP subdomains. The
purpose of subdomains is to form groups of clocks which are chronologically
independent from the other domains. The clocks in one group typically use
the same communication paths as other clocks.
