In this paper we present a summary of the state of the art concerning community detection in distributed computer architectures, for instance so-called P2P systems. The main algorithms for the extraction of communities are reviewed. Each set of nodes that constitute a community may also overlap with other communities due to the fact that nodes are shared between them. Thus, the the need to detect such communities has led us to examine the software that exists for their detection.
