Feature Overview:
uTP is an alternative communication method for BitTorrent traffic that allows the client to automatically regulate its bandwidth usage to avoid adversely impacting your internet connection. This will allow you or other users on the network to download their torrents but still allow others on the network to function with little difference. This does not require any additional setup.
In addition, uTP in this version has added its own form of STUN, a method of getting incoming connections without direct connectivity to the Internet. This allows µTorrent to punch holes through routers and firewalls to increase connectivity and improve speeds. It is even possible to connect two firewalled peers through uTP’s NAT traversal feature.
More details on uTP
UDP trackers are a different protocol for tracker communication that uses significantly less processing power on the tracker end. It’s important for us to support this because trackers have limited resources, so this should allow them to support many more users with their current hardware and not crash under the load.
The transfer cap settings were added in response to various users who have ISP-mandated caps on how much data they can download/upload in a month. Now you can track your usage in MB (with a handy graph to visualize it) and even configure µTorrent to stop torrenting once the limits are exceeded. Currently, you can configure the time interval, the data cap and whether it should stop based on only download, upload, or both combined.
As a privacy notice, this traffic data is not sent back to us or anyone.

Saw the light of the long-awaited Mac-version of the product uTorrent, the popular BitTorrent-Client, allowing users to share data over networks P2P.
Recall that the project uTorrent for Mac was launched nearly two years ago. Initially, developers planned to develop a solution of «zero», using as a basis library libtorrent, but last year it was decided that porting an existing Windows-version on a new platform.
The current version at the moment is on the status «beta», and is currently only operating system on computers sLeopard Intel Mac. In the near future, the developers promise to save the product from the majority of detected «bug», and to provide support for Mac OS Tiger.

uTorrent – a free client for networks BitTirrent (P2P), operating under OS Windows: 98/ME, NT/2000, XP, 2003 and Vista. The main difference from other uTorrent torrent-clients are small in size with a rather large functional capacity and a simple, friendly interface. uTorrent took less than 220 KB on the disk, uses minimum system resources and not to the whims of iron, will work fine even on very old PC. I think uTorrent is the best torrent client for the network and will not cause difficulties when downloading movies, games and music from well-known torrent trackers!
Main features of uTorrent:
• You can adjust the speed of downloading and impact
• Complete setup cache files on disk
• uTorrent supports DHT and PeerExchange
• Automatic download torrent from the RSS news feeds
• Support the work through a proxy server and connect to HTTPS
• Available encryption protocol
• UPnP support Unicode and all versions of Windows
• The program interface can be customized to your liking
• Localization in 38 languages, including Russian
• The program can be run in Linux and Mac using Wine

Super-seeding – a special mode in the distribution of some BitTorrent-clients, trying to minimize the amount of data that give the appearance of distributing up to the first download. John Hoffmann realized for the first time in his BitTornado client in mid-2003.
Mechanism
Client-supersid Peeroo invites everyone to download just one segment of the file, which is not yet at other peers. Then the LED does not give this Peeroo following segments until you receive confirmation from other peers that they too have received this segment.
Thus, supersid trying to avoid the impact of the same segments, and tries to give only to those segments piram that actively transmit them to others.
Are a prerequisite for the effective presence on the distribution of only one CIDA and at least two (but preferably more) licherov, that they may share segments.
Supersid not included in the formal specification of the protocol BitTorrent. It should be noted that the use of client-supersidom does not require any support in the other clients participating in BitTorrent distribution.
Application
Supersid recommended that you use only for the initial distribution of the file, and only one distributed.
The main purpose of supersida – before the first download distributing had to pay as little as possible (usually 105% to 120% of the file). Therefore supersid indispensable for distributing to pay for the amount of outgoing traffic.
Typically, the distribution of superside allow to minimize the time that is faster to get the first download. However, in some cases, the inclusion supersida may slow raprostranenie file. The effectiveness depends largely on the impact speed tilting.
Mode is not recommended supersid Kachan, and Sidamo in the distribution, where sidov more than one.

BitTorrent (literally, pp. «Bitstream») – peer-to-peer (P2P) network protocol Cohen for the cooperative exchange of files over the Internet.
The files are transmitted in parts, each torrent-client, receiving (downloading) of these parts, at the same time preference (downloads) to other customers, which reduces the burden and dependence on the source of each client and provides data redundancy.
The first torrent-client «BitTorrent» Bram Cohen created the Python 4 April 2001, launching the first version was held on 2 July 2001.
There are many other programs customers to exchange files from BitTorrent.
The operating principle of the protocol
How it works BitTorrent: load on the distributor of the file is reduced due to the fact that customers are beginning to share data immediately, even if the file does not dokachan them to the end.
Before you start downloading the client connects to the tracker, he said his address and the hash sum of the requested file, which in response the customer receives the addresses of other clients to download or distributing the same file. The client periodically informs the tracker about the process and obtain an updated list of addresses.
Customers are connected with each other and exchange segments of files without the direct involvement of tracker, which is only regularly updates information on the contracts for the exchange of clients and other statistical information. An effective network BitTorrent necessary that as many customers have been able to accept incoming connections. Incorrect changes to the NAT or firewall can prevent this.
When connecting clients directly exchange information on their segments. Clients wishing to download segment, sends a request and if the second client is ready to give, receive the segment. The client then verifies the checksum for the segment and notifies all connected peers about having him in this segment.
Each client is able to temporarily block the return to another client (eng. choke). This is done to make better use of the channel output. In addition, if you choose – one to unlock preferred piram, which are transferred to this client a lot of segments. Thus, the feasts with good impact velocities encourage each other on the principle of «you – I, I – you».
Exchange of segments is on a «you – I, I – you» symmetrically in two directions and in random order. Clients periodically communicate with each other on their segments. Data transfer starts when both parties are interested in it, that is, each side has segments, which have no other. The number of transferred segments are calculated, and if one party discovers that sends on average more than taking it to block (engl. choke) returns. Thus, the protocol provided protection against licherov.
Upon receipt of the full file, the client goes into a special mode of operation, in which he pays only the data (becomes Sid).
Clients periodically inform the tracker on the changes in the status of the download and update the lists of IP-addresses.

Posted On June 27, 2009 at 3:47 pm in BitTorrent, bitTorrent tracker, uTorrent description, uTorrent information
BitTorrent-Tracker – a web server, which coordinates BitTorrent-Client.
Coordination of client
The main function of BitTorrent-tracker – handling customer queries.
Each time a client calls with a request to the tracker, which indicated:
* Unique hash sum torrent file;
* TCP-port, where the client is waiting for connections from other clients;
* The amount of data that the client had time to share with other clients;
* And some other information.
This treatment is a normal HTTP-request, which information is encrypted using a special protocol Bencode (en: Bencode).
If the BitTorrent-client open more than one active torrent file, then each use a separate request, in no way connected with others. The intervals between requests for each individual torrent settings depend on the client, and usually range from 30 to 60 minutes.
BitTorrent-tracker, using the hash value as a unique identifier file that lists of IP-addresses and ports involved in the distribution of each individual customer. Every client in response to another request tracker returns a list, and the client uses it to establish connections with other clients.
Role tracker
Thus, the tracker «associates» clients with each other, but is not directly involved in the exchange of distributed data files. Moreover, in principle tracker can work without having any information about these files, as customers have reported to him just the hash sum file.
Tracker regarded as «weak» place of BitTorrent, because when the device is disconnected, new customers just can not mutually «find». This has already been involved in the distribution of customers may continue to file for some time, gradually losing those who are disabled or who has changed the dynamic IP-address.
To resolve this problem, can be used stand-trackers or special protocol such as DHT.
Additional features
Most implementations trackers, except for the coordination of clients also have additional features available to users with browsers through a regular Web server, often with a different address or port than the interface for the client.
Thus, virtually all trackers statistics show the distribution, ie the number of sidov and peers in each hand, the overall volume of data transferred between clients and other information available to them.
Most trackers are used to store the torrent files, and their descriptions.
Private (private) trackers
Private (English private) tracker – this tracker, limiting access to users, usually requiring the registration of the account and demand the maintenance of «ranking», at a certain level.
One of the reasons for the emergence of private trackers is the asymmetry of user access channels to the Internet. Average user during download torrent manages to give other users a small amount of data, many users after receiving a file is closed immediately torrent client. As a result of reduced availability of torrent, and the original distributors of the file falls unduly heavy workload.
As a rule, private trackers record statistics (top) of each user by the number of «downloaded» and «given» to other users, and require the maintenance of a minimum ratio of these two variables. As a result, the availability and speed of downloading torrent on a private tracker is usually higher than in the open.
To identify a specific client tracker uses an IP-address of the user, or a unique key for each user (called user key and pass key), add trackers in the torrent file when downloading it yourself.
A rating system is, and the negative side: discrimination of users with a narrow channel of impact. Most of the impact that user does not, the reason for that – other people who have more upload-channel, and give much more and faster. This user is very difficult to restore your rating, especially if it deals with malovostrebovannymi files. In the end, stay at a private tracker turns out for him a constant headache on how to maintain the rating.
