Statistics
When NetProbe2000 emulates slave node it provides the following list of metrics:
• Offset from master: The difference in time between slave and master.
• M to S Delay: The master to slave path delay.
• S to M Delay: The slave to master path delay.
• Mean Path Delay: The mean delay between master and slave.
• Round Trip Delay: The sum of M to S and S to M delay.
• Path Asymmetry: The difference between master to slave and slave to master
delay.
• Clock Drift: The difference of master and slave clock frequencies in ppm units.
• IPDV (Inter-Packet Delay Variation): The difference between the delays of the
current and the previous packets (RFC5481).
• PDV (Packet Delay Variation): The difference between the delays of the
current packet and the minimum packed delay observed in current test
interval (RFC5481).
• IPG (Inter-Packet Gap): The variation in arrival of a message.
