Resource Discovery Infrastructure
AuthorsW. Hoschek, K. Berket, and D. Agarwal
For large distributed multi-disciplinary science collaborations it is a difficult problem to find data, results, and resources. Typically, defining centralized storage and managing the resources as a single domain solves this problem. But this solution scales poorly and does not allow for opportunistic use of resources and data repositories. As a much more scalable alternative, we propose to research, design, develop, evaluate and benchmark a reusable software infrastructure for Peer-to-Peer resource discovery, thereby enabling a range of innovative research directions building on it. The infrastructure will address a number of scalability problems in a general way. It will provide flexible and uniform transport-independent resource discovery mechanisms to reduce both the client and network burden in multi-hop P2P systems. We hope that this research and resulting infrastructure will enable new types of DOE science applications.
Further future work will focus on enabling heterogeneous P2P networks of services for science applications, integrating many distinct infrastructures and application components. For example, such heterogeneous P2P networks provide an innovative and reusable productivity tool suite by integrating collaborative P2P chat, service discovery, databases, network monitoring, data sharing tools as well as end-to-end security mechanisms.
