"In P2P search (a.k.a. distributed search), each individual connected to the network serves its local index as a source of search. Instead of having a central company and a central server, each participant of the network is a search repository. Since we are talking about web indexing and web searching, a user's internet cache might be their contrib...
"A P2P application is different from the traditional client/server model because it acts both as a client and a server. That is to say, while they are able to request information from other servers, they also have the ability to respond to requests for information from other clients, at the same time. Figure 1 shows the architecture of a P2P networ...
"A typical peer-to-peer application has the following key features: • Peer discovery. The application must be able to find other applications that are willing to share information. Historically, the application finds these peers by registering to a central server that maintains a list of all applications currently willing to share, and giving that ...

URL = http://www.mpi-inf.mpg.de/departments/d5/software/minerva/index.html ""Each peer is considered autonomous and has its own local search engine with a crawler and a corresponding local index. Peers share their local indexes (or specific fragments of local indexes) by posting meta-information into the P2P network. This meta-information contains compact statistics and quality-of-service information, and effectively forms a global directory. However, this directory is implemented in a comple...

Description. "The Chord project aims to build scalable, robust distributed systems using peer-to-peer ideas. The basis for much of our work is the Chord distributed hash lookup primitive. Chord is completely decentralized and symmetric, and can find data using only log (N) messages, where N is the number of nodes in the system. Chord's lookup ...

2009年10月11日 · Technical Description. "DHTs obviated the server from P2P networks. A DHT is a hash table that partitions the keyspace and distributes the parts across a set of nodes. For any new content added to the network, a hash (k) is calculated and a message is sent to any node participating in the DHT. This message is forwarded from node to node until ...
