Summary of How Traceroute Works (Building a Movie Scene 'Trace' Map) - Computerphile

00:00:00 - 00:15:00

This video explains how the traceroute network utility works. It shows how to send a traceroute command to an IP address and plot the results on a map. Finally, it demonstrates how traceroute works by using it to route to a random location in different parts of the world.

• 00:00:00 Traceroute is a network tracing tool used to determine the route packets take between two points. By setting the route time to live to very low, a router can be tricked into looping, filling up its memory and causing problems.
• 00:05:00 Traceroute lets you trace the route a packet takes through a network. This can be useful in diagnosing network issues or tracing packet flow across the internet.
• 00:10:00 In this video, computer scientist Alan Cox explains how the traceroute network utility works. First, he shows how to turn a string of text into an ip address. Then, he shows how to send a traceroute command to an ip address and plot the results on a map. Finally, he demonstrates how traceroute works by using it to route to a random location in different parts of the world.
• 00:15:00 This YouTube video explains how computer-generated "Trace" maps work, and how they are used to create movies scenes. The map is created by tracking the signals traveling through the network, and the speed of the pulses tells us the rate at which the signal is moving.
