TCP/IP means many things to many people. Some think it’s a collection of formal specifications. Other think is a glob of stuff that makes the Internet work. I suspect it’s something in between.
Rather than focusing on the fundamentals of the protocols like in most of my articles, this piece will focus on the bits that are the most interesting. I’d call it advanced TCP/IP, but a number of the most noteworthy topics I’ll be covering are quite core to the protocol suite.
