UDP-based_Sliding_Window_Protocol

一个支持pop3的简单的邮件收发程序(a simple mail procedures)

从libnids得到TCP重组的数据，当libnids的状态为NIDS_JUST_EST时，表示TCP建立连接，在此时给TCP流增加一个flow_id用来标识此连接；当libnids的状态为NIDS_DATA时，表示接受数据，当有新的数据到达时，根据flow_id把数据push到相应的流表中，为之后的数据分析做准备。因此，可以在此框架上增加符合http协议的应用解析(Data TCP libnids restructuring, when libnids status to NIDS_JUST_EST, said the TCP connection is established, at the same time adds a flow_id to TCP flow is used to identify this connection When libnids status to NIDS_DATA, accepted data, when new data arrives, according to flow_id to push data to the corresponding flow table, prepare the way for after data analysis. Can be increased on this framework, therefore, in accordance with the application of the HTTP protocol parsing)

用socket编程实现点对点通信，TCP客户端程序，TCP服务器程序，以及UDP点对点聊天通信。(Point to point communication, TCP client, TCP server, and UDP peer chat communication socket programming.)

简化Sock连接。采用队列保存Sock的收发消息包，保证消息的处理顺序。(Simplify the Sock connection)

局域网监控系统采用vc++6.0编写，需要oracle数据库(LAN monitoring system)

简易TCP通讯服务器端，QosClt为客户端。多个客户端间的通讯需要基于服务器，即通过服务器转发。(Simple TCP communication server, QosClt for the client. Communication between multiple clients need a server-based, that is transmitted through the server.)

创建一个新进程范例。这是孙鑫视频中的范例，能帮助初学者了解进程的相关知识，可以看看，虽然比较简单(create a new process in vc++)

简单TCP双向通讯例子，实现客户端服务器端的双向通讯。(Simple the TCP bidirectional communication example, to achieve the client server-side two-way communication.)

说明：  远程开机的程序，有mfc，vc++,非常实用(Remote boot-consuming procedures, mfc, vc++, Very useful)

允许用户网络chat交流并且更新，共享文件 (Internet chat allows users to exchange and update, share files)
