What is Gnutella2?
Gnutella2 is a modern and efficient peer-to-peer network standard and architecture designed to provide a solid foundation for distributed global services such as person to person communication, data location & transfer, and other future drvices.
Why is it needed?
Peer to peer technologies have become mainstream over recent years, and there are already a significant number of P2P networks in various stages of development and operation. How does yet another network help?
Gnutella2 is unique amongst the currently operating peer to peer networks in several important ways:
Many of the most successful networks are "closed", owned by a single entity with restrictions or fees constituting a barrier to participation. This is not a viable model for an open, general purpose network. Gnutella2 is an open architecture where anyone is welcome to participate and contribute. The network has been designed to allow such diversity without the need for messy hacks or compromises in integrity. The majority of networks are devoted to a single purpose, often the sharing of files. This is certainly a popular application for peer to peer technology, but it is by no means the only application. Gnutella2 is designed as a general purpose network which can be used as a solid foundation for any number of different peer to peer applications - vanilla file sharing, communications tools or other ideas which are yet to be conceived.
Some peer to peer networks have been developed with similar general purpose goals, however, they have been unable to compete in the most popular application of the day, which is file sharing. For a general purpose network to succeed, it must be able to compete with purpose-specific networks in the most popular purpose. Gnutella2 is not only able to compete with the current popular file sharing specific networks, it outperforms them.
What is the Scope of Gnutella2?
The Gnutella2 Network is perhaps the most easily recognised component. It is a new high-performance peer to peer network architecture upon which a variety of distributed applications can be built, such as file sharing applications, communication tools, etc.
The Gnutella2 Standard is a set of requirements for building applications which operate on the Gnutella2 network in different capacities. It specifies the minimum compliance level required to be recognised as a Gnutella2-compatible application. Compliance with a Gnutella2 Standard ensures participating applications provide a minimum acceptable level of service to other network participants.
