Content Structure

Application Layer

  • HTTP, DNS, SMTP, P2P
  • Socket programming

Transport Layer

  • UDP, TCP
  • Reliable data transfer, congestion control

Self-Study Tips

Start from the application layer. This is the book's signature approach — begin with HTTP and DNS (what you know), then go deeper.

Do the Wireshark labs. Each chapter has accompanying Wireshark labs that let you see real network packets.

Pair with Stanford CS144. This book covers theory; CS144 provides hands-on labs. Together, they're the perfect combination.

Notes

This is the best textbook for networking beginners. If you only read one networking book, this should be it.
