[网络编程] MyChatClient
本课题是设计一个聊天室软件，包括服务器端和客户端，主要功能为：
服务器端：初始化socket, 创建服务器端，在特定的端口上等待来自客户的连接请求，并且能够记录所有成功的连接；接受用户传送来的连接判断命令，并向用户发出响应命令；支持多个客户端的连接，在服务器和多个客户端之间进行数据传输；能接受用户传送来的聊天信息，然后所有链接的客户端转发。
客户端：建立和维护与服务器的连接，并且随时检测连接的状态；能够把用户输入的信息及时发送到服务端；有一个消息显示区，还可以显示历史信息。
This topic is the design of a chat room software, including server and client, the main function of:

Client: establish and maintain a connection with the server at any time, and detecting the connection state; to send the user input information to the server; a message display area, can also display the historical information. (2017-07-18, C/C++, 24915KB, 下载4次)
[网络编程] BT-protocol-specific-analysis
BT由如下几部分组成：.torrent文件、种子提供站点、目录服务器和内容发布者/下载者。.torrent文件是一个文本文件，包含了 tracker信息和文件信息两部分。tracker信息主要是BT下载中需要用到的tracker服务器的地址和针对tracker服务器的设置；文件信息是指将目标文件计算处理后再根据BT协议的B编码规则网编码后得到的信息。BT的主要原理是把提供下载的文件虚拟分成大小相等的块，块大小必须为 2Kbyte的整数次方（由于是虚拟分块，硬盘上并不产生各个块文件），并把每个块的索引信息和Hash验证码写入.torrent文件中，所以.torrent文件就是被下载文件的“索引”。种子提供站点也就是.torrent文件的提供站点，为下载者提供.torrent文件下载服务。目录服务 器记录被下载的文件的索引信息及下载该文件的用户的信息（主要是IP地址及端口号）。早期的BT协议只支持tracker（种子发布站）服务器，这种目录服务器是集中式目录与分布式查询的混合型；在BT协议的升级版本中，增加了对DHT（分布式Hash表）网络的支持，该网络中目录服务器是分布式的。本文的讨论只涉及 tracker服务器。内容发布者/下载者是BT网络的主体，最终的下载由它们完成

Torrent file is a text file that contains the tracker information and file information in two parts. BT download tracker information is mainly used in the tracker needs to address and settings for the tracker file information is then processed to calculate the target file the agreement under the BT network B encoding rules to be encoded information. BT s main principle is to provide the downloaded file into the same size of the virtual block, the block size must be 2Kbyte integer power (because it is a virtual block, each block on the hard disk does not create the file), and the index of each block Information and Hash verification code is written. torrent file, so. torrent file is downloaded the file "index."
