Indeed. PTP (various, not-necessarily compatible, versions) is at the core of modern ethernet-based audio networking: Dante (proprietary, PTP: IEEE 1588 v1), AVB (IEEE standard, PTP: 802.1AS), AES67 (AES standard, PTP: IEEE 1588 v2). And now the scope of the AVB protocol stack has been expanded to TSN for industrial and automotive time sensitive network applications.
