Operation
FastTrack like P2P systems such as eDonkey, BitTorrent, Gnutella, and can be classified as a network semicentralizada. That means there are multiple servers that handle the information flowing through the system, especially without a drive and endanger the whole network. FastTrack uses a method to alleviate the burden on those, which are called supernodes, which were devised by the Dutch company Kazaa BV. Most of the components that make up this network are known customers (including seeds and peers), servers and nodes. To know that a customer is a person able to connect to the system, a server is a computer that has ample resources to handle the traffic flowing on a given network and a node is the machine of a customer to have ample resources shared with the system, easing the burden on the network. Supernodes or superpeers is an innovative feature of this network. The main objective of these is to improve the speed and manner in which information flows, managing some of the actions that need more resources: traffic and searches (the most representative). But the peculiarities of these clients do not end here, any user that connects to the network, using the respective client-can be asendido to this range. But to qualify in this way must meet certain requirements in terms of resources: with a large bandwidth, a computer with a processor and memory to handle and send all the information flowing through the network . Sometimes not know if it is part of the set of supernodes FastTrack. Note that this classification does not alter in any way, nor the search user’s connection speed. Neither harms the security of the computer, or the saturation of operations, because that only accounts for 10 of the resources of this .
Central servers managed indeed supernodes, and these in turn the connections between users and the searches. Thus, the load on the servers is minimized big way as they should not drive and connect to the network users, but administering the aforementioned super .
In addition to the system or supernodes superpeers, FastTrack has other features that identify it. For example, a system has parts (a system by which you can download the same file from multiple computers) similar to eDonkey and Bittorrent, but with a more complex level of development. Even with the depth that gives this point, the download speeds are affected by the possibility to download different parts from different sources simultaneously. While not often use all available bandwidth, FastTrack achieved acceptable transfer rates.
FastTrack like many protocols for P2P networks, has a verification algorithm itself. In this case it is a fairly controversial: UUhash, which is capable of checking large files quickly, even on computers with limited resources. However, since its development allows corruption within the files of sight, so often fails in its work. This aspect of the algorithm is used and which ingeniously uses even companies like RIAA or MPAA to incorporate fake files on the network and avoid potential copyright violations.
