If you ask for the name of the head of University in the campus, you'll get hundreds of answers in reality, and thousands to millions on the web.
If a search brings too many results, the nodes, through which you are connected (your nearest 5 friends) can get overloaded, because every answer has to go through them, for they don't give out your \"phone number\", but their own and hand the answer to you. The Friend-of-a-Friend model has certain disadvantages, which have their source in the way searches are performed. The biggest problem with this model (among others) is that you have to be a part of the clique before you can use it. The original Gnutella used 7 steps (called HTL: Hops To Live). That would be enough to reach every human being on this planet. After the first step the number of people reached is 5, after the second it is 25, after the 5th 3125, after the 7th 78,125 and after the 14th about 6.1 billion. One asks five others, each of whom asks 5 others and so on. You can imagine the original model of the Gnutella network as friends phoning each other to get information. The now resulting implementation drops all of the old Gnutella protocol except for the connection handshake and adopts an entirely new search algorithm. In November 2002, Michael Stokes formally and unilaterally announced the creation Gnutella2 protocol to the Gnutella Developers Forum, which caused a schism among the developers, and lead for the modifications no to be supported in several Gnutella applications since the original proposal did conflict with other vendors concepts (in specific LimeWire and Bearshare). Gnutella2 is also called Mike's Protocol since the first changes and implementation resulted from a single developer Michael Stokes. The result of a fork of the Gnutella protocol, due to the failing of the developers community to reach a consensus on the evolution of the protocol. It is called MP (Mikes Protocol) or the Shareaza Protocol by most Gnutella developers, while its developer called it Gnutella2, a name which gave his program (Shareaza) much media coverage and created and creates much controversy and aversion against it in the_gdf. One sibling of Gnutella deserves special attention, even though some developers of current clients would deny it. Gnutella in new implementations also supports Tiger tree hashing (TTH) for for file transfers.

And while Gnutella was initially stated as a fully-distributed information-sharing technology, later versions of the protocol are a mix of centralized and distributed networks with "Servers" ( Ultra or Super peers) and "Clients" ( Leafs or Nodes ).Ī Gnutella client software is basically a mini search engine (offering an alternative to web search engines) and file serving system in one. Is not a project of the FSF or related to GNU software tools).
It is an open network, and the origin of its name may be found more easily by eating too much Nutella, than at GNU. The developers are careful to ensure the greatest possible backwards compatibility.ĭespite the name, Gnutella isn't GNU-Software, though some Gnutella clients are GPL-licensed. In this way all programs share a common base, while the protocol also allows for client specific options. After that they are documented in the rfc-gnutella. The specifications are discussed and created by the GDF (the gnutella development forum), an open Mailinglist for developers, with by this date over 1000 members. That means, unlike most other networks, everyone can write a client which can access the GNet, if it fulfills the publicly available specifications. Gnutella is an open file sharing Network originally created by Justin Frankel of Nullsoft.
