1. 1 A Blueprint for Introducing Disruptive Technology into the Internet Larry Peterson Princeton University / Intel Research

2. Catch-22 The Internet is a huge commercial success –increasing our dependency on it –making it increasingly ossified Ossification makes the Internet vulnerable –susceptible to attacks –increasingly brittle –growing management burden Ossification also marginalizes researchers –difficult to deploy new solutions

3. Overlay Networks Add a new layer to the network architecture –use overlays to deploy disruptive technology Examples –geographically distributed services (e.g., DHT, CDN) –network measurement & anomaly detection Problem –how do you experiment at scale?

4. PlanetLab 1000 viewpoints on the network includes both edge sites and network crossroads each researcher gets a slice of PlanetLab

5. Dual Roles Research testbed –run experiments –large set of geographically distributed machines –diverse & realistic network conditions Deployment platform –run services continuously –support a user community (realistic workload) designdeploy measure
