  1. Overlay Infrastructure Hari Balakrishnan MIT Laboratory for Computer Science http://nms.lcs.mit.edu/ron/

  2. 4 Interesting Areas • Data sharing / resource discovery / data management apps • Build on DHTs • Location: PCs in homes, labs, … • Driver: cooperative, secure archiving (e.g., CVS) and backup service for all our data • New routing & forwarding models • Content routing, RON, OverQoS (QoS overlays) • Location: network “edges”; key is AS diversity • Driver: Predictable network performance, e.g., for previous set of apps • Measurement research • Set up a large-scale overlay for monitoring network performance • Location: “Deep in the network”, at colo’s, etc. • Driver: How well is our prediction doing; how could we do better? • Internet-wide ASPs • Serving software (e.g., “HTTP-based virtual memory”) • Location: Edges / datacenters • Driver: Managing and upgrading software on all our handhelds, desktops, laptops • 1 line research goal: let’s design predictable systems

  3. Challenges • Research • Getting predictability • Design for “flux”: system will have no steady state • Logistics • The 4 (and more) areas have pretty diverse requirements • Management (cf. RON/Chord experience)
