软电话 从功能分为：服务器端和客户端 服务器：记录所有客户的信息，对客户的登陆、注销等请求进行响应 客户端：利用UDP协议与服务器和被叫或主叫客户端进行通讯 点对点通讯中的请求和响应消息是通过SIP协议来完成传输的，音频信息（压缩后）是同构RTP协议来完成传输的-Soft phone functionality is divided into: server-side and client-server: a record of all customer information, customer landing, write-offs, such as in response to client requests: the use of UDP protocol with the server and the called or caller client communication point of point communication in the request and response messages through the SIP protocol to complete the transmission, audio information (compressed) is isomorphic RTP protocol to complete the transmission

数据传输，数字传输，或数字通信的物理数据传输（数字比特流）

应用背景 参照官方代码写的消息发布测试程序，用于压力和性能测试。 TestBasicPublish.java 用于发布测试消息，参数代码内有描述 -？ 可查看 TestBasicGet.java 用于单挑消息获取 TestBasicConsume.java 用于批量消息获取 关键技术 RabbitMQ 是信息传输的中间者。本质上，他从生产者（producers）接收消息，转发这些消息给消费者（consumers）.换句话说，他能够按根据你指定的规则进行消息转发、缓冲、和持久化。 RabbitMQ 的一些常见的术语： Producing意味着无非是发送。一个发送消息的程序是一个producer(生产者)。

该文件内含两个文件，一个是串口调试助手，另一个是用VC编写串口调试助手的源程序，对串口调试助手及其实现原理感兴趣的，是一个很有用的资料。-The document contains two papers, one is the serial debug assistant, and the other is used to prepare serial debug VC source assistants, assistant to the serial debug and realize the principle of interest is a very useful information.

xul调用c++xpcom例子,这几天在研究Xul ,调试通过了一个Xul做界面，通过js调用c++开发的xpcom的例子。感觉步骤比较繁杂，配置环境也颇费了点时间，所以就把整个开发过程作了一个记录-xul call c++ xpcom example, these days in the study Xul, debug interface, the adoption of a Xul do, through the js call c++ development xpcom example. Sense steps to more complicated, and configure the environment has also gone through quite some time, so put the entire development process was a record of
