By the nature of a Ping, there is no way to only see how quickly traffic is travelling in one direction.

If you are looking to measure the line quality between the two offices, what I would recommend would be the QOS one way sensor. This would give you a decent amount of information about the connection between the master and the probe that you would have to set up at the other office.

Why "QoS One Way sensor" do not show "one way" time?

That should be shown in the "Time to Last Packet" - Channel.

No, "Time to Last Packet" show very high values 20000...30000 ms ("QoS One Way sensor" show same time as "QoS Round Trip sensor") (but Ping RTT =10 ms between offices)

Yes, the "Time to Last Packet" is the time for the entire traffic (first to last packet). Single Packet Times are not available for the one way QoS-Sensor. But you could calculate it manually in a Sensor Factory, by dividing the Time to Last packet by the number of Packets.

in this case it show incorrect result: (20000...30000)/1000 = 20...30 ms "one way time"???

But "QoS Round Trip sensor" show "RTT(Average)"=14 ms!

Yes, because the RTT is just the packet, where as the calculation includes the delay between the packets.

Again, that is not shown on the QoS-One Way Sensor. You could use a simple Ping-Sensor as alternative.
