Wow. That is awesome, I skimmed through it and it looks like something I will enjoy. I've still got my Tanenbaum Computer Networks book from 1996 and the first chapter starts with OSI, then TCP/IP, and explains the differences and why OSI failed.
It doesn't seem like a "take down" as much as a re-iteration of all the things IBM, DEC, GE and various Telcos did wrong when implementing OSI. I could reduce it to one sentence: "Everyone was so intent on monetizing their own networking implementation they never thought enough about interoperability."
Not only isn't that an accurate summary of Graham's book, it isn't even a topic discussed in the first half of the book, which is all I've read so far. I suspect it isn't a topic discussed in the book at all; can you back up your assertion with some quotes?
