ABSTRACT
In recent years, various kinds of overlay networking technologies have emerged as an active area of research and development. Overlay systems, especially peer-to-peer (P2P) systems, are technologies that can solve problems in massive information distribution and processing tasks. The key aim of many of these technologies is to be able to offer deployable solution for processing and distributing vast amounts of information, typically petabytes and more, while at the same time keeping the scaling costs low.
