How a PTP Timing Aware Switch with Integrated GM Simplifies Network Synchronization https://www.khushicomms.com/blog/ptp-timing-aware-switch-with-integrated-gm A PTP Timing Aware Switch is a network switch built to support IEEE 1588 Precision Time Protocol (PTP) for high-accuracy time synchronization across packet-based networks — and when it ships with an integrated Grandmaster (GM), it can act as both the timing source and the timing transport in a single box.
