A near-term architecture for deploying Pip

Pip, a new Internet Protocol (IP) that is a candidate to replace IP Version 4, is discussed. Pip solves the dual problems of scaling and address depletion that currently plague IP and provides new features such as provider selection. Pip also has a means of evolving to new features, such as real-time flow handling. Pip´s architecture, host input processing, evolution to real-time flows, fast options handling, and address management are described. The IP to Pip transition scheme is outlined.<>
