Server Load Balancing

I just finished reading Server Load Balancing. It was an OK book, but there's only about 50 pages of real content. The rest is specific information on how to configure various vendors hardware/software, which I'm guessing can be found in their manuals. It was a book purchased for our company library almost five years ago that I had been meaning to read. Five years later I finally got around to it. It taught me a little bit about networking and made me realize there's quite a bit I'd like to learn about general networking.
