仿照飞信，网络编程。像飞信一样，自由添加客户端用户。(Modeled Fetion, network programming.)

说明：  linux环境下的一个防火墙程序的源代码，下载自sourceforge(a firewall program's source code, downloaded from sourceforge)

聊天程序的源码，对学习socket编程很有帮助。(Chat program source code, useful for learning socket programming.)

说明：  《STM32库开发实战指南》基于STM32F103芯片，紧紧围绕“库”的分析和使用展开。在大量实例的基础上，本书对于如何综合运用固件库开发项目给出了具体的范例；在固件库的使用和学习的基础上，又进一步讲解了结合嵌入式实时操作系统、TCP/IP协议栈进行嵌入式系统开发的方法，让读者循序渐进、系统地掌握基于STM32官方库进行开发的方法。(Based on STM32F103 chip, STM32 library development practice guide focuses on the analysis and use of "library". On the basis of a large number of examples, this book gives a specific example of how to comprehensively use the firmware library development project; on the basis of the use and learning of the firmware library, it further explains the method of embedded system development combined with embedded real-time operating system and TCP / IP protocol stack, so that readers can gradually and systematically master the method of development based on STM32 official library.)

在局域网中，管理员常常需要将某条信息发送给一组用户。如果使用一对一的发送方法，虽然是可行的，但是过于麻烦，也常会出现漏发、错发。为了更有效的解决这种组通信问题，出现了一种多播技术（也常称为组播通信），它是基于IP层的通信技术(In a LAN, administrators often need to send a certain message to a group of users. If one to one transmission method is used, it is feasible, but it is too troublesome, and often there will be missed and wrong hair. In order to solve this kind of communication problem more effectively, there is a multicast technology (often called multicast communication). It is a communication technology based on the IP layer.)

一个MVC3架构的网站，非常使用，有源码、CSS、数据库等等(A MVC3 web framework, very used, source, CSS, database, etc.)

针对M2M海量业务在LTE-A调度中的新算法改进，用Matlab测试其丢包率、时延以及系统吞吐量.Pf算法的对比部分(Simulation process, the improved algorithm that compares with the classical algorithm, through the simulation data system latency, packet loss probability of the system as well as a comparative analysis system throughput, improved assessment of the correctness and performance of the algorithm.)
