Figure 7-1

Basic operating principle of NTP

In the figure above, Ethernet Switch A and Ethernet Switch B are connected via the

Ethernet port. They have independent system clocks. Before implement automatic

clock synchronization on both switches, we assume that:

Before synchronizing the system clocks on Ethernet Switch A and B, the clock on

Ethernet Switch A is set to 10:00:00am, and that on B is set to 11:00:00am.

Ethernet Switch B serves as an NTP time server. That is, Ethernet Switch A

synchronizes the local clock with the clock of B.

It takes 1 second to transmit a data packet from either A or B to the opposite end.

The system clocks are synchronized as follows:

Ethernet Switch A sends an NTP packet to Ethernet Switch B. The packet carries

the timestamp 10:00:00am (T

) that tells when it left Ethernet Switch A.

When the NTP packet arrives at Ethernet Switch B, Ethernet Switch B adds a local

timestamp 11:00:01am (T

) to it.

When the NTP packet leaves Ethernet Switch B, Ethernet Switch B adds another

local timestamp 11:00:02am (T

) to it.

When Ethernet Switch A receives the acknowledgement packet, it adds a new

timestamp 10:00:03am (T

) to it.

Now Ethernet Switch A collects enough information to calculate the following two

important parameters:
