Monitoring Peer to Peer Systems

چکیده
In this paper, we are concerned with the distributed monitoring of P2P systems. We introduce the P2P Monitor system and a new declarative language, namely P2PML, for specifying monitoring tasks. A subscription is compiled into a distributed algebraic plan which is described using an algebra over XML streams. We introduce a lter for streams of XML documents that scales by processing rst simple conditions and then, if still needed, evaluating complex queries. We also show how particular tasks can be supported by identifying subtasks already provided by existing streams.

متن کاملTAC: A Topology-Aware Chord-based Peer-to-Peer Network
Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...
