SendSocketTest为客户端，发送数据用，SocketTest1为服务器，接收数据用。共发送10个数字作为测试

使用UDP打洞的p2p聊天程序，程序分为一个服务器和一个客户端，适用于穿越一般情况下的NAT

TCP&UDP测试工具，可以方便的监督端口接收发送的数据，监督端口是否监听成功，既可以做客户端，也可以做服务端。

socket编程源代码TCPUDP socket编程源代码-包含客户端服务器端，TCP和UDP协议.rar

分为客户端和服务端，可实现UDP在局域网的广播

主要是为探索一下这个校验和算法具体怎么实现的，需要的朋友可以参考下

对应前面发的C++ windows, socket UDP和TCP/IP通信Client端， 代码都是在windows环境vs下调试过得

用Java写的基于UDP无连接的简单图形界面聊天程序，可实现内网或外网运行本程序计算机的文本通信聊天，可群聊
