"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...

2013年1月20日 · A number of other anonymity-preserving systems, including Gnunet and I2P, borrowed from Freenet's design. To my knowledge Freenet is probably the highest-profile decentralized anonymous p2p network (obviously Tor is better known, but it isn't really decentralized due to its global relay list). Freenet is also the only anonymous P2P system that ...
2008年3月23日 · Dijjer streams downloaded files directly to your web browser, or your audio or video player, as they are downloaded. Dijjer uses "UDP hole-punching" to communicate through firewalls without any need to manually reconfigure them. Dijjer forms one unified P2P network, rather than a separate network for each file, which allows it to scale up much ...

Learning II is learning to learn. Learning III - Hyper-complexity: Learning III is a change in the process of Learning II, e.g. a corrective change in the system of sets of alternatives from which a choice is made. It works much as Learning II but on a higher level of abstraction. Bateson points out that this level of learning is never achieved ...
