The IAB discusses the End-to-End principle of IP in this very important draft for all of you that want to understand IPv4 versus IPv6, NAT or not to NAT and IP-telephony architecture discussions.
The end to end principle is the core architectural principle of the Internet. In this document, we briefly examine the development of the end to end principle as it has been applied to the Internet architecture over the years. We discuss current trends in the evolution of the Internet architecture in relation to the end to end principle, and try to draw some conclusion about the evolution of the end to end principle, and thus for the Internet architecture which it supports, in light of these current trends.
