Stateless Core: A Scalable Approach for Quality of Service in the Internet: Winning Thesis of the 2001 ACM Doctoral Dissertation Competition

The fundamental aspect of the Internet architecture that distinguishes it from other network technologies (such as X. 25 and ATM) is that it is c- nectionless (vs. connection-oriented) and stateless (vs. stateful).
