's Pastry system, that can be easily used to build an application that creates an overlay network with a limited number of library calls. The library is intended to serve as both a usable complete structured peer-to-peer system and a starting point for further research. It includes some of the current work in locality optimization and soft-state operations. The system contains both a leaf set of ''neighbor nodes'', which provides fault tolerance and a probabilistic invariant of constant routing progress, and a PRR-style routing table to improve routing time to a logarithmic factor of network size. Chimera is currently being used in industry labs, as part of research done by the
