Approximate Aggregations in Structured P2P Networks

In corporate networks, daily business data are generated in gigabytes or even terabytes. It is costly to process aggregate queries in those systems. In this paper, we propose PACA, a probably approximately correct aggregate query processing scheme, for answering aggregate queries in structured Peer-to-Peer (P2P) network.

Peer-to-peer aggregation techniques dissected

In peer-to-peer systems,where these sources are distributed over many machines, aggregation centres around routing data from the sources to a sink location where the aggregate value is needed.

Designing a Super-Peer Network - Stanford University

A super-peeris a node in a peer-to-peer network that operates both as a server to a set of clients, and as an equal in a network of super-peers. Super-peer networks strike a balance between the inherent efficiency of centralized search,

Configure an Aggregate Interface Group - Palo Alto Networks

The firewall cannot detect the mode of its peer device. Set the Transmission Rate for LACP query and response exchanges to Slow (every 30 seconds—the default) or Fast (every second). Base your selection on how much LACP processing your network supports and how quickly LACP peers must detect and resolve interface failures.

Approximate Queries in Peer-to-Peer Systems | SpringerLink

The main challenge in P2P approximate query processing is to select the optimal subset of peers to which the query is forwarded. However, the selection criteria for this subset are completely different for top-k and aggregate queries.While in top-k the goal is to identify the peers holding top objects, approximate aggregate querying algorithms need to find a representative sample of peers.

A Simulation-based XML Routing Synopsis in Unstructured ...

the Internet. The deployment of an XML query shipping system over P2P networks requires a specialized synopsis to capture XML data in routing tables. In this paper, we propose a novel graph-structured routing synopsis, called kd-synopsis, for deployment over unstructured super-peer based P2P networks. This synopsis is based on

Abstract. We investigate the problem of processing historical queries on a sensor network. Since data is considered to have been already collected at the sensor nodes, the main issue is exploring the spatial component of the query in order to minimize its cost represented by the energy consumption.
