Traceroute is a network diagnostic tool for displaying the route and measuring transit delays of packets across an IP network. The round-trip times of packets received from each host on the route is recorded. Each step in the route is called a hop, and the sum of the mean times of each hop is a measure of the total time taken to establish the connection. Thus, traceroute provides more detailed information than Ping, which only computes the final route-trip times from the destination.
