IEEE 1588 Message Formats
The TCP payload follows immediately the TCP header.
26.3.6 IEEE 1588 Message Formats
26.3.6.1 Transport Encapsulation
The Precision-Time-Protocol (PTP) datagrams are encapsulated in Ethernet frames using
the UDP/IP transport mechanism, or, optionally, with the newer 1588v2 directly in Ethernet
frames (Layer 2). Typically multicast addresses are used to allow efficient distribution of
the synchronization messages.
