What is the difference between bittorrent and gnutella

It's major weakness is that it doesn't have a search built into the protocol, so people have to find the torrent by other means usually through web sites. However, this is also an advantage, because it makes it easier for people to track what files are spam, fake, or malicious. Unlike Gnutella clients, all the Bittorrent clients seem to be focused on downloading a file, sharing for a period of time, then stop sharing permanently.

If a file is not popular, this effectively kills the torrent. Also, it can be inefficient because the same exact file can be shared in multiple torrents, but the clients in one torrent can't share clients in the others. Gnutella seems to be better suited for smaller, less popular files. The major differences is that the Gnutella network is one big network, it has search built in, and the clients are focused on always sharing everything. In a sense, it's like a large, highly distributed data store.

Gnutellas blessing and curse is it's decentralized nature. Because it's so decentralized, it makes it hard to determine what files are fake or malicious, and there's a ton of spam on the network. I, personally, like Gnutella's approach better. I've always been a fan of anarchy and chaos What are your thoughts on these protocols, p2p in general, and the future of p2p?

Re: Gnutella and Bittorrent Gnutella is a virus haven. Gnutella represents one of the first systems that gained huge following after the downfall of Napster, its simple but scalable design and its distributed nature allowed it avoid the legal pitfalls that plagued other more centralized networks.

Following from the original Gnutella model, other peer networks have adopted its concept and applied it in different ways e. Also Freenet is significant for this survey because its enhancements to the basic search mechanism in Gnutella made locating data in the network was more efficient without have to result in a centralized model by introducing indexing servers. First developed by Justin Frankel and Tom Pepper of Nullsoft later acquired by AOL in and released under the GPL license the Gnutella protocol presents a simple framework for sharing files on the internet that is scalable and robust.

Gnutella falls into the class of pure P2P; peers in the network are joined by point-to-point connections to a set of neighboring peers to form an unstructured overlay. These point-to-point connections in Gnutella are maintained using predefined messages described by the Gnutella protocol table 1. In order to join the Gnutella P2P network a peer has to contact a known member of the network and request to establish a Gnutella protocol connection to the remote peer, once connected to the network new peers learn about other nodes through the protocol message they receive from the network.

Initial discovery of known peers in the network is not part of the protocol definition, though some out-of-network means such as downloading a predefined list of known peers from a server are popular methods. A peer joining the network shares an area in its local storage by creating an inverted list of files that are contained in the share space and evaluates queries it receives from the network against the inverted list.

Contained information. Used to actively discover hosts on the network. A peer receiving a Ping descriptor is expected to respond with one or more Pong descriptors.

The response to a Ping. Includes the address of a connected Gnutella peer and information regarding the amount of data it is making available to the network. IP address and port number of the responding peer; number and total kB of files shared. The primary mechanism for searching the distributed network. A peer receiving a Query descriptor will respond with a QueryHit if a match is found against its local data set.

Minimum network bandwidth of responding peer; search criteria. The response to a Query. This descriptor provides the recipient with enough information to acquire the data matching the corresponding Query. IP address, port number, and network bandwidth of responding peer; number of results and result set. A mechanism that allows a firewalled peer to contribute file-based data to the.

Peer identifier; index of requested file; IP address and port to send file to. Table 2. Gnutella uses TCP as its underlying transport protocol but it is abstracted by an application level protocol which describes how peers communicate. Each message in the network is always preceded by a descriptor header message that describes the payload of the Gnutella message. Message descriptor headers are assigned unique identifier so that a peer that has already seen a message before can ignore it helps to avoid looping in the network.

Descriptor headers also have a TTL Time-To-Live value and a hops count value which keeps track of the times the message has been forwarded. Messages received by a peer are forward to other peers that are connected to it, in this way message are flooded in the network to ensure it reaches it intended destination.

To control the scope of flooding of Gnutella messages, the TTL value is set in the descriptor header specifying the number of times the message should be forwarded before it can be discarded. In the example below figure 2. The ping message is forwarded to other neighboring nodes which reply with a pong and decrement the TLL value. Once the TTL value of the message is zero, the message is dropped from the network.

Figure 2. Peers that receive the query message evaluate it against its own data store and if they have resources that match the query respond back with a QueryHit message to the original peer. The Gnutella protocol does not support file download over its application level protocol rather a target peer must contact the source peer directly using IP routing to establish a HTTP connection to download the file.

Bittorrent represents a major innovation in the world of P2P computing. By its self Bittorrent is not a full fledged P2P content sharing protocol, but it relies on other global components to allow users in the network locate file and work in P2P fashion [6]. One of the main problems in current P2P system is that they do not scale well when downloading large files. A typical internet connection has high download and significantly lower upload, so in the traditional method when downloading file the source peer bears the grunt of the download since it must appropriate portions of it limited upload bandwidth among the requestors of the file.

This approach is neither scalable nor efficient and ensuring fairness in the system would result in poor download rates for all downloaders.

File pieces are downloaded in an unordered fashion from the source so that peers can exploit the use of peer connection to other downloaders to obtain file pieces they do not have. File pieces in Bittorrent are described in a small meta-info text file that ends with a.

The hash value of the file pieces is used as a checksum allowing nodes to check the validity of a piece that they have downloaded. Peers download files by participating in a file swarm which is an ad-hoc network of peers that are temporarily assembled to distribute a particular resource.

Since Bittorrent is not really a P2P content sharing protocol, it relies heavily on global components to allow nodes locate resources and also find each in the network. The global components in a Bittorrent P2P network include torrent servers, web search engines and the tracker server. Torrent servers in Bittorrent are ordinary web servers on the internet functioning as a data stores for. Users wishing to share files in the Bittorrent network first have to create a.

To reduce pollution insertion of low quality or garbage files in the network, a moderator system is used to weed out fake content [6]. There are three levels of moderatorship in the network: moderators, unmoderated submitter, and moderated submitter. A normal user who injects content irregularly is called a moderated submitter. Moderator status in a Bittorrent P2P network is the equivalence of system administrator for the torrent server; they have complete control over what can be inserted into the network.

The role of web search engines in the Bittorrent P2P network is to allow peer locate the. Web search engine play the role of a global directory indexing server of available resource in the Bittorrent P2P network; they accept user queries for a.

Seed seeder. A peer with a complete copy of the resource and still offers it for upload seeding. Leech lecher. Peer that contacts other peers to barter for chunks. Together, all peers downloading a resource. Mechanism which allows client to prevent other clients from uploading to it.

Share ratio availability. Ratio of complete copies of the file in the swarm. Is expressed as a percentage of number of peers with copies of the file and total number of peers in the swarm. Each peer with complete copy adds 1 to the total. A peer with only a fraction of the complete file adds the fraction to the availability.

The possibility to get a virus on p2p networks is equal with the possibility to get one from the web; if you are looking for bad things you get bad things, let's say you are looking for a ''crack'' on Google, you click and you download a trojan, the same with p2p. Peoples are penetrating the most sofisticated systems every day so we can say that a p2p network is more secure than other. Search In. Share More sharing options Followers 0.

Draconian Guppy Posted February 23, If you download an infected file on bittorrent you simply stop seeding it. If you download an infected file on eMule you delete it and you're no longer sharing it.. In the end, it's all the same. Posted February 24, Posted February 26, Darkdashing Posted February 26,
