2004-11-12  A peer-to-peer (P2P) data management system consists essentially in a network of peer systems, each maintaining full autonomy over its own data resources. Data exchange between peers occurs when one of them, in the role of a local peer, needs data available in other nodes, denoted the acquaintances of the local peer.

Robust and efficient aggregate query processing in peer

The ability to approximately answer aggregation queries accurately and efficiently is of great benefit for decision support and data mining tools. A P2P network consists of numerous peer nodes that share data and resources with other peers on an equal basis. Unlike traditional client-server models, no central coordination exists in a P2P system; thus, there is no central point of failure.

2021-11-15  Hence, many Approximate Query Processing Techniques (AQPTs) have been presented in the literature which provide approximate query results using sampled data, and thus achieve noticeable computational efficiency. Recently in the literature, AQPT is presented for the approximate execution of simple non-join aggregate queries.

Second, we propose "Digest", a two-tier system for correct and efficient query answering by sampling. At the top tier, we develop a query evaluation engine that uses the samples collected from the peer-to-peer database to continually estimate the running result of the approximate continuous aggregate query with guaranteed precision.

Query Routing and Processing in Peer-To-Peer Data

Sharing musical files via the Internet was the essential motivation of early P2P systems. Despite of the great success of the P2P file sharing systems, these systems support only "simple" queries. The focus in such systems is how to carry out an efficient query routing in order to find the nodes storing a desired file. Recently, several research works have been made to extend P2P systems to be ...

RFC 3706 Detecting Dead IKE Peers February 2004 Peer B, on the other hand, defines its less urgent DPD interval to be 5 minutes. If the IPSec session is idle for 5 minutes, peer B can initiate a DPD exchange the next time it sends IPSec packets to A. It is important to note that the decision about when to initiate a DPD exchange is implementation specific.
