how is latency calculated?
By adding the serialization delay to put a fixed sized packet (normally 64 bytes) to the over all round trip delay. The serialization delay is calculated by (packetsize in bytes * 8)/data rate speed. This happens on both ends of the overall round trip delay so it happens 4 times on a round trip.
So
1) serilization delay on the sender side
2) delay while traveling the network
3) serilization delay on the last hop to destination
4) serialization delay on the receiving host to put packet onto wire
5) dealy while traveling the network
6) serialization delay on the last hop to the original sender.
That's your latency.
