Peer-to-Peer (P2P) systems are emerging Internet applicationsthat exploit the resources distributed in the networkedges. The resources are aggregated through ad hoccommunication among the participating peers, instead ofbeing provided from the centralized servers. The distributednature of P2P systems avoids performance bottleneck, singlepoints of failure, and censorship of centralized servers.P2P systems also accommodate dynamics in the networkand exploit unused resources. P2P systems can generallybe classified into unstructured and structured systems. Inthis paper, we focus on structured P2P systems and reviewsome well-known systems. Their essential features are abstracted,which leads to a tree model to characterize a majorfamily of structured P2P systems.
