As network computing becomes more complex and the world more interconnected, the need for more precise time synchronisation has greatly increased. Network time protocol (NTP) and IRIG time code have been the most common protocols governing time transfer, but IEEE 1588 Precise Time Protocol (PTP) is revolutionising time synchronisation by improving accuracy and reducing cost. While certain other precise sync protocols require significant investment in hardware and cabling, PTP makes highly precise timekeeping possible using the most widely deployed medium for network connectivity – Ethernet.
