GossipLib: A library for gossip-based applications

Participants : Heverson Borba Ribeiro, Davide Frey, Anne-Marie Kermarrec.

GossipLib is a library consisting of a set of JAVA classes aimed to facilitate the development of gossip-based application in a large-scale setting. It provides developers with a set of support classes that constitute a solid starting point for building any gossip-based application. GossipLib is designed to facilitate code reuse and testing of distributed application, and provides also the implementation of a number of standard gossip protocols that may be used out of the box or extended to build more complex protocols and applications. These include for example the peer-sampling protocols for overlay management. GossipLib also provides facility for the configuration and deployment of applications as final-product but also as research prototype in environments like PlanetLab, clusters, network emulators, and even as event-based simulation. The code developed with GossipLib can be run both as a real application and in simulation. Currently the implementation of GossipLib includes approximately 9K lines of code, and is used in several projects by ASAP, including HEAP, AllYours-P2P, and Behave.
