NTP and PTP training course description

This course looks at timing and synchronization as provided by NTP and PTP. Hands on sessions primarily involve using Wireshark to analyse the protocols.

What will you learn

• Recognise the importance of timing and synchronisation.
• Explain how NTP works.
• Explain how PTP works.
