使用VS中的VC++下面的CLR编写，主要目的用Socket模拟TCP通信协议，实验内容如下：i. 实现滑动窗口协议，窗口大小为5 ii. 模拟采用三次握手机制，显示出ACK、ack、Seq等标识位和参数 iii. 必须采用应答机制、超时计数器技术、帧编号判重技术、重传技术 iv. 校验和技术 a) 校验和s的计算：设要发送n字节，bi为第i个字，s=(b0+b1+…+bn) mod 256 v. 在接收端，设置随机数，根据随机数执行相关操作，0代表正常，1代表帧丢失，2代表帧出错，3代表应答帧丢失（即不发生应答帧） vi. 必须使用图形界面， a) 按批次（发送端一次发送的报文）显示相关内容 b) 发送端：显示发送的数据、是否重传、本次帧序号、接收到的应答帧的序号 c) 接收端：显示接收到的数据、本次帧序号、本次随机选择的出错情况、发送应答帧的序号、是否重复 要先打开Server端启动监听，再打开Client端进行连接，三次握手之后开始通信。
