BitTorrent is a protocol for distributing files. it identifies content by URL and is designed to integrate seamlessly with the Web. its advantage over plain HTTP is that when multiple downloads of the same file happen concurrently, the Downloaders uploadTo each other, making it possible for the file source to support very large numbers of Downloaders with only a modest increase in its load. A BitTorrent File Distribution consists of these entities: An ordinary Web Server A static 'metainfo' F

BitTorrent protocol specification) Original BitTorrent protocol specification (English) BitTorrent is a file distribution protocol. It identifies content through URLs and can interact seamlessly with the Web. It is based on the HTTP protocol and has the following advantages: if multiple Downloaders concurrently download the same file, each downloader also uploads the file for other Downloaders at the same time, the file source supports a large number of users to download, but only increases the

about keyboard events from Windows can be divided into two types: keystroke messages and character messages. For keystroke combinations that produce characters that can be displayed, Windows also sends a character message while sending a keystroke message. Some keys do not produce characters, such as the SHIFT key, the function key, the cursor movement key, and

I. Summary The client and storage server actively connect to tracker server. Storage server proactively reports its status information to tracker server, including statistics such as disk space remaining, file synchronization status, file upload download times, and so on. Storage Server connects all tracker servers in the cluster and reports their status to them

Overview:(1) Each tracker service invokes the Tracker_relationship_init function at startup to start a thread relationship_thread_entrance. The thread will confirm the relationship of each tracker every few seconds, and if leader changes or goes down, the leader will be re-elected.(2) Call flowMain function|-int Tracker_relationship_init ()Creating Threadsif (Result=pthread_create (tid, thread_attr, \Relati
