	Gnutella - Wikipedia, the free encyclopedia
		Gnutella (pronounced /nʌˈtɛlə/ or /gnʌˈtɛlə/) is a file sharing network used primarily to exchange files.
		Gnutella is not associated with the GNU project; see GNUnet for the GNU project's equivalent.
		The Gnutella protocol remains under development and in spite of attempts to make a clean break with the complexity inherited from the old Gnutella 0.4 and to design a clean new message architecture (such as Gnutella2), it is still one of the most successful file-sharing protocols to date.

	A Quantitative Analysis of the Gnutella Network Traffic
		Additionally, their Gnutella Crawler Implementation is in some sense static since it starts from a pre-specified seed file of peers and relies on the fact that it will discover new nodes on runtime.
		We believe that is due to the fact that Gnutella connections are relatively unstable which leads peers in a endless effort of discovering new peers rather than to the fact that peers are joining and leaving the network at fast paces.
		Gnutella users seem not interested in other type of content such as software, images or text since their aggregate percentage is not very large.

	Gnutella Protocol Development
		Gnutella is an Open Protocol, where the specifications are public and free of any patent.
		This set of connected nodes carries the Gnutella traffic, which is essentially made of queries, replies to those queries, and also other control messages to facilitate the discovery of other nodes.
		It is a scheme to have a hierarchical Gnutella network by categorizing the nodes on the network as leaves and ultrapeers.

		Gnutella crawler aren't open source because they can harm the network a lot.
		Yes I am ware of the harming effect a crawler can have on the network, but I think it is better to have an optimized crawler (open source), than to let amatuers develop their own crawlers.

		Although we use these applications widely, we don't know how the each topoloy of them is organized and how each user contributes to this system exactly because of the nature of peer-to-peer system which lacks dedicated, cetralized infrastructure, but rather depend on the voluntary participation of peers.

		Although this method is still usable, it is too slow to capture enough data for a topological overview of the Gnutella network as it requires initiating full Gnutella connections; this involves several roundtrips to perform the header processing.
		The Gnutella Developers Forum (GDF) is an open forum where developers of Gnutella servents discuss changes and extensions of the Gnutella protocol.

	USENIX IMC '05 Technical Paper
		A detailed measurement study of the modern two-tier Gnutella network is therefore timely and allows us to compare and contrast the behavior today from the earlier measurement studies, and to gain insights into the behavior and impact of the two-tier, unstructured overlay topologies which have been adopted by most modern P2P systems.
		In a nutshell, any captured snapshot by a crawler will be distorted, where the degree of distortion is a function of the crawl duration relative to the rate of change in the overlay.
		The two-tier overlay topology in modern Gnutella (as well as other unstructured P2P networks) consists of ultrapeers that form a “spaghetti-like” top-level overlay and a large group of leaf peers that are connected to the top-level through multiple ultrapeers.

	Gnutella (Site not responding. Last check: 2007-10-12)
		Gnutella is the third-most-popular file sharing network in the Internet, following eDonkey 2000 and FastTrack.
		While figures vary from hour to hour and day to day, Gnutella is thought to host on average approximately 2.2 million users, although around 400,000-500,000 are on at any given moment.
		Finally, when user A disconnects, the client software saves the list of nodes that it was actively connected to, or was keeping as a backup, for use the next time it attempts to connect.

		The Gnutella network is made up of varying random nodes from across the world, connected in an ad-hoc manner.
		For example, having each crawler come from a different IP address may change the dynamics of the Gnutella network as many different nodes attempt to connect.
		A crawler behaves differently from a typical Gnutella client, tending toward shorter sessions with any given node and to more fully explore the other nodes on the network.

		In Gnutella, the crawler uses the ping/pong message to discover the peer hosts and learns of their status information such as bandwidth and the number of files shared.
		Gnutella shows high resilience in terms of attacks, but might suffer badly if the attacks are well planned and effect high responsibility peers.
		One major difference between Napster and Gnutella is that Napster relies on a cluster of centralized servers to maintain an index of files that are currently being shared by active peers.

		Their crawler made use of the Gnutella host discovery mechanism to perform a pseudo breadth first search of the network.
		Distributing the crawler allowed the researchers to complete the crawl in constant time using just a handful of workstations.
		They also noted that their topology data could be questionable due to the sometimes high RTT of messages as well as the crawler's inability to discover network connections within a private network.

	A Measurement Study of Peer-to-Peer File Sharing Systems
		The goal of our Gnutella crawler is the same as our Napster crawler: to gather nearly instantaneous snapshots of a significant subset of the Gnutella population, as well as metadata about peers in captured subset as reported by the Gnutella system itself.
		Another interesting point is the presence of a Gnutella peer that apparently shares 0 files but 730 MB of data; clearly a bug in the software or a case of malicious peers misreporting the amount of data they have to share.
		As this graph shows, Gnutella presents a highly robust overlay in the face of random breakdowns; for a maximum node degree of 20 (which is approximately what we observed in the real Gnutella overlay), the overlay fragments only when more than 60% of the nodes shutdown.

		According to the file sharing website Slyck.com, Gnutella is the third-most-popular file sharing network in the Internet, following eDonkey 2000 and FastTrack.
		As the size of the Gnutella network has grown and its developers have fought excess traffic consumption, global searchability of the network has diminished.

		We have built a "crawler" to extract the topology of Gnutella's application level network.
		The two major findings we focus on are: (1) although Gnutella is not a pure power-law network, its current configuration has the benefits and the drawbacks of a power-law structure, and (2) the Gnutella virtual network topology does not match well the underlying Internet topology, hence leading to ineffective use of the physical networking infrastructure.
		Although Gnutella network might fade, we believe the P2P paradigm is here to stay.

		Without covering the technical aspects of the protocol in depth, a brief explanation of Gnutella’s communication protocols is helpful to better appreciate the search in action.

		The concrete goal of the project is to compare the network properties of Gnutella peers to those of PlanetLab hosts.
		First, you should construct a Gnutella crawler that walks over the Gnutella network, discovers peers, discovers which files they are sharing, and performs some sample downloads from these peers to determine the download bandwidth available from that peer.
