Chimera and Tapestry

In today's chaotic network, data and services are mobile and replicated widely for availability, durability, and locality. Components within this infrastructure interact in rich and complex ways, greatly stressing traditional approaches to name service and routing. We advocate the use of structured peer-to-peer overlays as a routing infrastructure that improves routing resilience to loss and attacks. Two of our protocols, Chimera and Tapestry, provide decentralized location-independent routing of messages to named keys. The Chimera and Tapestry projects are being developed at the CURRENT Lab for secure and reliable networking under the supervision of Prof. Ben Zhao.

• NEW: An updated Chimera release (version 1.01) is now ready for download here.
• News: we are developing a new variant of the Tapestry protocol, called Chimera. Chimera is a lightweight P2P protocol implemented in C suitable for bundling with user applications.
• Check out the Cashmere anonymous routing project.
