The goal of Chordjerl (pronounced: cordial) is to be an reusable Erlang implementation of the Chord distrubuted key lookup protocol.
Chord is a lookup protocol for efficient location of a node that stores a desired data item in a decentralized, peer-to-peer system. The Chord algorithm provides the foundation for a reliable, efficient, scalable decentralized distributed hash.
Chord provides support for just one operation: given a key, it maps the key onto a node.
You can read more about Chord in the paper from Stoica et al. "Chord: A Scalable Peer-to-peer Lookup Protocol for Internet Applications" (http://pdos.csail.mit.edu/papers/ton:chord/paper-ton.pdf)
Here's a simple network of 7 nodes where m (the number of bits in the hash function) = 7
Here's a a more complex, but stable, network of 20 nodes with m=15
