| Abstract
|
This document describes the current state of the Internet from the
architectural viewpoint, concentrating on issues of end-to-end
connectivity and transparency. It concludes with a summary of some
major architectural alternatives facing the Internet network layer.
This document was used as input to the IAB workshop on the future of
the network layer held in July 1999. For this reason, it does not
claim to be complete and definitive, and it refrains from making
recommendations.
