Collaborative P2P Systems Mini Survey

1 INTRODUCTION This report is a survey of the literature about the topic " Collaborative P2P Systems ". In the remaining part of the report first, collaborative P2P systems with examples will be explained. Second, brief information about JXTA will be provided. Last, summary of research papers related with collaborative P2P systems will be given. P2P systems provide adaptation, self-organization, fault tolerance and massively distribution and replication of large amount of resources. According to [1], while using these benefits, collaborative P2P systems furthermore aim to allow application-level collaboration among its users. Collaborative P2P systems are generally event-based applications that a group of users use. When a change occurs at a peer, an event in that peer is triggered and the data produced by this event is sent to all the peers in that group. Upon receiving information regarding to an event, receiving peer's view of the application is updated accordingly. In order to satisfy the needs of collaborative P2P systems the authors of [1] state that the developed applications should support real-time communication, quality of service, security, reliability and the location of peers should be known. Example of application level collaboration includes chat applications, online games and shared applications used in business, education, etc… One of the most famous collaborative P2P applications is Groove. Next section discusses an overview of Groove. Groove is a collaborative P2P application that allows its users to communicate, share their contents and allows them to participate in joint activities. Groove allows its users to collaborate
