9:00 a.m.–10:30 a.m.

Opening Remarks, Awards, Keynote Keynote Address PlanetLab: An Open, Community-Driven Infrastructure for Experimental Planetary-Scale Services David E. Culler, University of California, Berkeley, and Intel Research Network systems researchers have generated a host of ideas for distributed services that spread across the Internet, following the emergence of CDNs and P2P file sharing, but have had only limited means to try them out. PlanetLab builds upon a confluence of several maturing technologies, including remote cluster management, virtual machines, overlay routing, and resource containers, to provide a wide-area testlab for deployment and instrumentation of novel services. Services are deployed as a "slice" of distributed virtual machines. Intel Research seeded the initial phase of 101 nodes at 42 sites across 7 countries. The community is progressively redefining the architecture as a set of distributed services as it grows towards thousands of nodes.

9:00 a.m.–10:00 a.m.

Invited Talk Fast, Reliable Data Transport Michael Luby, CTO of Digital Fountain, Inc. Digital Fountain has developed a reliable transport that provides the fastest, most predictable global data delivery solutions available. The reliability of these solutions is based on fountain codes, a new class of erasure codes designed for high-speed software implementations that can be applied to any size data. Traditionally, transport reliability is provided by sending small pieces of the original data in packets and using retransmissions of lost packets triggered by ACKS/NACKS to ensure reliability. Using fountain codes, packets are generated on-the-fly from the original data, and a receiver only needs to wait for the minimal number of packets to arrive to recreate a perfect copy of the original data, independently of which packets are lost and without feedback to the sender. Flow and congestion control can be provided completely independently of reliability, e.g., packets can be sent at a fixed rate or according to a congestion control protocol that operates independently of the reliability protocol.
