2 P2P or Not 2 P2P?

In the hope of stimulating discussion, we present a heuristic decision tree that designers can use to judge the likely suitability of a P2P architecture for their applications. It is based on the characteristics of a wide range of P2P systems from the literature, both proposed and deployed.Comment: 6 pages, 1 figur

Report of the NSF Workshop on Research Challenges in Distributed Computer Systems

This report 1 summarizes recommendations from a workshop on research challenges in distributed computer systems, sponsored by the National Science Foundation. A program committee solicited input from the research community by asking researchers to submit position papers that identified grand challenges in distributed systems, invited researchers based on their submissions, and selected a few position papers for presentation at the workshop. Most of the workshop was organized around break-out sessions, in which we refined the research challenges and identified the facilities needed to carry out future research as well as what the distributed systems community can contribute to the facility. Information about the workshop, including the full program, the selected submissions, and the slides of the presentations and the break-out sessions, is available a
