IRIS: Infrastructure for Resilient Internet Systems

Home | News | Press | People | Related Projects | Talks | Papers | Software | Support | Private


The IRIS project is developing a novel decentralized infrastructure, based on distributed hash tables (DHTs), that will enable a new generation of large-scale distributed applications. DHTs are robust in the face of failures, attacks and unexpectedly high loads. They are scalable, achieving large system sizes without incurring undue overhead. They are self-configuring, automatically incorporating new nodes without manual intervention or oversight. They provide a simple and flexible interface and are simultaneously usable by many applications.

This work is funded under NSF Cooperative Agreement No ANI-0225660.  proposal  contains more details regarding DHT's and the goals and plans of the IRIS project, including references to the technical literature.  The Related Projects   link has pointers to more specific documentation on prior initiatives.


  • The 2004 IRIS student workshop will be held at MIT on Nov. 7 and 8. The program is here. All IRIS students are invited to attend and to present a poster at the poster session on the 8th.
