I wonder if anyone could recommend resource or resources such as a good book that:

• explains how all the important protocols work and interact. I’m interested in those that are relevant in a typical home network and used over the Internet
• explains in detail how ADSL Internet connections work to the level of depth necessary so that I’m able to tweak and measure performance settings
• starts from the beginning but attempts to provide proper understanding rather than idiot-oriented steps to follow

Basically, I’m interested in how these technologies work and tend to be implemented in hardware and software rather than “here’s what to do if…”

I’m interested in Computer Networking by Andrew S. Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.
