140    2.6 Coral
141    Coral is a peer-to-peer content distribution system that creates self-organizing clusters of nodes that fetch
142    information from each other to avoid communicating with more distant or heavily-loaded servers. Coral is
143    designed to index local data, such as the files in a node's web cache, to ensure that content is replicated
144    exactly in proportion to its use. Coral uses two novel mechanisms to achieve scalability and high performance.
145    First, a new abstraction called a distributed sloppy hash table (DSHT) lets nodes locate nearby copies of a
146    file without causing hot spots, regardless of its popularity. Second, based on the DSHT interface, a
147    decentralized clustering algorithm allows nodes to can find each other and form clusters of varying network
148    diameters.

150    Efficient peer-to-peer lookup based on distributed tries.
