In a network world, ping basically helps us to measure round trip time(RTT) from source to destination using ICMP Echo Messages. It doesn't provide, what path the packet takes to each router and the no. of routers the packet have traversed. Normally network engineers provides the no. of attempts e.g. 10 in PingER for each probe. From these 10 attempts, they measure four different metrics. Min Rtt, Max RTT, Avr RTT and Packet loss. Using these metrics, we can measure the average queing delay along the whole path by subtracting MaxRTT from MinRTT.
Lets L = size of the packet and R = data rate of the whole path.
Average QD= MaxRTT - MinRTT.
Average TD = L/R
It is practically, impossible to get a very good estimate of Queing delay at each hop along the path using ping.
