I disagree. TCP/IP is really pretty close to both minimal and clean given the problem it is solving (reliable transport across unreliable links). Anyone who starts out designing a protocol which is "simpler" than TCP eventually realizes that they wound up designing 90% of TCP--generally badly.

The fact that TCPv6 (which had pretty much a blank slate) does not throw out much of the fundamental architecture of TCPv4 shows that TCPv4 made pretty much the right decisions.
