How the Internet Works

The Internet runs the world; it connects our devices, powers our businesses, and even talks to our thermostats. But how does it all happen? We will follow an adventurous young web browser from the moment a hapless user presses "enter" and witness the trials and tribulations of many packets. Ride alongside the most fearsome syscalls as we learn how the Internet works!

A few of the topics we will cover:

  • DNS and UDP
  • Static routing and ARP
  • IP, Ethernet, and 802.11
  • BGP and autonomous systems
  • DNS reply
  • HTTP request
  • TLS handshake (protocol only, not cryptography)
  • TCP handshake
  • HTTP reply
