Most of the Internet's traffic is data-oriented, while the Internet is based on sending messages to end points. As a result, the efficient multicast is difficult to implement on Internet's scale, and various attacks such as DoS and SPAM are easy to launch. In this paper, we describe a clean slate approach for a publish/subscribe based networking: Publish/Subscribe Internet Routing Paradigm (PSIRP). PSIRP aims to implement publish/subscribe networking without relying on existing networking protocols such as IP. Preliminary results suggest that a clean slate publish/subscribe approach is flexible and scalable to the Internet.
