(piece) contains a unique sha1 hash value. (Byte string type)PRIVATE: (Optional). The value of this key is of the integer type. If it is set to 1. The client must broadcast its own existence, and then obtain other peers by explicitly describing the trackers in the meta-information file. If it is set to 0 or not, it indicates that the client can obtain other peers in other ways, such as PEX peer exchange technology and DHT technology. "Private" can be interpreted as there is no external peer sou

user, a client. In this structure, users can transfer data to users, not all users from the same server to obtain data. By sharing data between users to reduce the pressure on the server, this is the idea of the peer-to approach. 2, BitTorrent Agreement FoundationBT protocol has undergone several generations of change, here we first talk about the most primitive BT protocol. Be aware that the BT protocol is a typical peer application. If you want to

Board = BitTorrent file = M.1209531185.AThanks to the original authorBitTrrent (BT) is a file distribution protocol that identifies content through URLs andJoint. Its advantage on the HTTP platform is that, at the same time, the downloader of an object continuously downloads each otherThis allows you to upload data to a large number of file sources with limited loads.A bt file distribution requires the

official website and other clients including the ARM platform can be downloaded.Precautions for use:1. If you choose Read-only synchronization (server-local), if you do not want to sync after the file transfer, remember to delete the synchronized directory on the local client, otherwise the server-side deleted the file, the local will automatically delete the file. Of course, read-write synchronization is more so.From zero technology: http://www.ldisp.com/a/linux/2013/CentOS-

Read BitTorrent SummaryI have read the BitTorrent source code for a while. The main clues are as follows:Parseargs|VRawserver = rawserver (doneflag, config ['timeout _ check_interval '], config ['timeout'], errorfunc = errorfunc)|VStorage = storage (files, open, path. exists, path. getsize)|VStoragewrapper = storagewrapper (storage, config ['Download _ slice_size '], pieces, info ['piece length'], finished,

Question: When you download an object online, a file is stored in one or more sections, and you are asked how to select the maximum number of files that can be downloaded within the specified traffic. The size of each segment is the same. Ideas: I used to store the answer in the DP array, and saved the answer in the subscript. I started to think about a backpack, but the memory was not enough and the time was not enough. In fact, this is the case. DP [I] [J] [0/1] saves the enumeration to the nt

Tutorial on how to build a P2P download service in a Linux environment-Linux Enterprise Application-Linux server application information. The following is a detailed description. The P2P protocols in Linux mainly include BitTorrent, aMule, and Gnutella. This article describes how to build a P2P service in the Redhat Enterprise Linux Advanced Server 4 environment. With the prevalence of the broadband network, the traditional HTTP and FTP methods for M

use of traditional HTTP and FTP this point to multi-point download is not enough to meet the needs of everyone. It can be connected and slowed down as the number of downloads increases. and peer-to-hand technology is a form of unconventional, greatly saving network bandwidth. Allows you to connect directly to other users ' computers, Exchange and search for files, instead of web browsing and downloading, to maximize the use of network bandwidth. It is very convenient. is a multi-point download

faster the speed. Traditional FTP, HTTP, and pub send files from the server to the client. Some problems may occur: the increase in the number of users requires high bandwidth and high server performance, it also affects the stability of the server. Therefore, many servers have limits on the number of users and the download speed, which causes a lot of inconvenience to users. While BT fundamentally solves this problem, BT adopts a method similar to pyramid scheme to achieve sharing. While downl

number of people using BT, the faster. The traditional FTP, HTTP, Pub is the file from the server to the client, which will appear some problems: the increase in the number of users required high bandwidth and server performance, but also affect the stability of the server, so many servers will have the user number of restrictions, download speed restrictions, This has caused a lot of inconvenience to the user. And BT fundamentally solve this problem, BT is a similar MLM way to achieve sharing,
