[P2P] P2PChatPlus 终结版

Description:

第一个版本发布已经有将近半年的时间，在这段时间里面发生了很多事情，让我很长时间都难以安下心来写程序。我是酷爱写程序的，但是当她变成谋生手段的时候，时常会无比的艰涩。有时候压力不仅仅来自困难的问题本身。　　说说程序本身吧，其实第一个版本只是实现了P2P的一小部分，而后一直不断的完善，到了第三个版本，我才算是彻底理解了UDP实现跨网关P2P，当然，这个版本也并不是完善的。比如说：在没有回朔功能的网关下两台计算机无法通信，没有对数据包进行完整性的判断……。其实事情总没有完善的时候吧。　　程序只是实现了基本的基于UDP穿NAT的P2P，其他还有TCP和UPNP等等的就等大家一起研究吧。　　写程序的过程中，在网上查了很多东西，绝大多数都是在互相抄啊抄的。其实问题也就是这么一点，没有必要长篇累牍的论述，可能我比较笨，理解的太慢了。时常感觉就差那么一点点，有人提点一下就好了，可是始终我都没有找到这样的人。　　所有的东西都在“连接过程.doc”里面可以找到，程序本身也就是实现了图上面的流程。在这个过程的基础上，完全可以实现一个基于UDP的P2P开发包，不过有时间再说吧…… 　　我的联系方式：　　MSN: m820126@163.com 　　Email: m820126@163.com 　　http://www.cwind.cn 　　有问题可以来问我，不过我平时事情比较多，如果不能一一回答也请见谅了。之前一直有人问TMMessageMemo找不到，其实这是我自己的开发包里面一个小组件，仅仅是用来显示消息的，如果你稍微用心地读一下代码，就会发现用一个Memo就可以替换掉了。这次为了避免再有这样的事情出现，我把“MMessageMemo.pas”一起打包进来了，自己装一下吧，如果你连安装组件都不会……我就不说什么了。

Description: 用UDP实现了p2p是的穿透,P2PServer运行在一个拥有公网IP的计算机上，P2PClient运行在两个不同的NAT后（注意，如果两个客户端运行在一个NAT后，本程序很可能不能运行正常，这取决于你的NAT是否支持loopback translation，详见http://midcom-p2p.sourceforge.net/draft-ford-midcom-p2p-01.txt，当然，此问题可以通过双方先尝试连接对方的内网IP来解决，但是这个代码只是为了验证原理，并没有处理这些问题），后登录的计算机可以获得先登录计算机的用户名，后登录的计算机通过send username message的格式来发送消息。如果发送成功，说明你已取得了直接与对方连接的成功。-achieved using UDP p2p is the piercing, P2PServer operation in a public IP with the computer, P2PClient running in two different NAT after (Note If two clients running on a NAT, the procedure may not be operating normally, It depends on whether you support the loopback NAT translation, see http :// midcom-p2p.sourceforge.net/draft-ford- midcom- p2p- 01.txt, of course, this problem can be made by the two sides try to connect with each other to resolve the IP network, but the code is to verify principle, not dealing with these issues), after the computer can log logged in a computer user name, after logged by the computer username send the message format to send information.

[P2P] p2framework_src.2.1.0.2.tar

Description: P2Framework是一个开源项目。这是一个高效率的平台，使分布式系统的开发变得更加容易。通过这一平台，你可以忘记许多烦恼和琐碎的事情在分布式系统的开发（如NAT /防火墙穿越，的UDP / TCP协议的交换机等）。主要的重点是在这个框架内，以减轻P2P的连接建立，数据和信息传输。与P2Framework ，开发商不需要照顾NAT穿越，防火墙/代理问题，可靠性的UDP和TCP短期发送/接收的问题（等）的点对点环境。例如，可能同行后面的NAT或使用HTTP代理上网。另一个例子是，开发商可能要处理UDP和TCP连接以同样的方式，例如，一个可能需要可以传递信息的UDP和TCP可靠传输数据块的块，而不是流。在P2Framework ，各种连接建立和数据传输的封装几乎相同的接口。您可以使用混合连接P2Framework来确定最佳连接你喜欢同伴之间。此外，所有的网络业务的非块P2Framework其中只有运行signle线程。因此，开发商不需要使用互斥。和P2Framework可以建立在双方的Win32和Linux平台。-P2Framework is an open source project. It is a highly efficient platform for making distributed system development much easier. With this platform, you can forget many annoying and trivial things in the distributed system development (such as NAT/firewall traversal, udp/tcp protocol switch, etc.). The main focus on this framework is to ease the P2P connection establishment, data and message transmission. With P2Framework, the developers do not need to care NAT traversal, firewall/proxy problem, UDP reliability and TCP short send/receive problem (etc.) in peer-to-peer environment. For example, peers may behind NAT or uses a http proxy to access Internet. Another example is that the developers may want handle UDP and TCP connections in the same way, such as, one may want to UDP can transmit messages reliably and TCP can transmit data block by block rather than stream. In P2Framework, all kinds of connection establishment and data transmission are encapsulated as almost the same interfac

[Audio program] The_Speex_Codec_Manual_Version_1.2_Beta_3

Description: Speex是一套开源的专门压缩声音的库，压缩的性能非常高，常用在VoIP或者其它网络程序中。Speex声称自己是不受任何专利限制，并授权根据修订后的BSD许可证发布。它可以用来与Ogg容器格式或直接在UDP / RTP协议下传输。这份是Speex的编码手册英文版，下面的地址是维基百科中关于Speex的介绍: http://en.wikipedia.org/wiki/Speex-Speex is a free software speech codec that may be used on VoIP applications and podcasts. Speex claims to be free of any patent restrictions and is licensed under the revised (3-clause) BSD license. It may be used with the Ogg container format or directly transmitted over UDP/RTP. The Speex designers see their project as complementary to the Vorbis general-purpose audio compression project. Speex is a lossy format, meaning quality is permanently degraded to reduce file size.
