The Generalized Precision Time Protocol (gPTP) is a protocol that supports the timing and synchronization of time-critical applications in the home according to IEEE 802
.1AS. It dealswith time-critical applications in bridged local area
networks. 802.1AS defines the requirements for a full-duplexpoint-to-point connection. The standard can handle communication across multiple network interfaces and thus act as an 802.1AS bridge.
