C语言写的点对点时延测量程序。时延测量精度：微妙。一个服务器一个客户端，采用面向连接的协议。测量原理：客户端向服务器发一条信息，记录此时的时间，服务器收到信息后返回一条信息，此时再记录时间，两次时间相减除以2即是本次通信的时延。

用c++编写的网络通信框架，适用于多客户端的网络通信 client: 模拟客户端程序 server: 模拟服务端程序 gateway:网关程序 启动：client.exe server.exe gateway.exe程序，client程序会网关gateway.exe发送消息 消息内容为字符：00004XXXX XXXX为字符，是使用 04d打印到BUF中的， gateway.exe收到client.exe发送的消息，此时从系统路由表中取到：B_HOST的信息，并把 收到的消息转发到server.exe程序，如果server.exe程序作相应处理，还可以作为应答，把 消息返回给client.exe，如果要这么实现的话，需要加流水信息-Using c++ to prepare the framework of network communication for multi-client network client: client simulation server: process simulation server gateway: Gateway proceedings: client.exe server.exe gateway.exe procedures, client program will be the gateway message send a message gateway.exe for characters: 00004XXXX XXXX for the characters, is to use 04d to BUF in print, gateway.exe received messages sent client.exe, this time from the system to check the routing table: B_HOST the information, and forwarded to the information received server.exe procedure, if the corresponding procedures to deal with server.exe, but also can serve as a response to the n
