这是一款教学实验的源代码，数据链路控制规程的演示，用SOCKET(UDP) 通信平台实现点对点数据链路控制规程，演示了滑动窗口控制协议（GO-BACK-N）的工作原理的理解。-This is a teaching experiment

计网数据链路层go back n协议源代码-go back n

实现go back n算法，模仿数据链路层的gobackn协议-To implement the Go-Back-N (GBN) protocol on top of UDP on both nodes to guarantee that all packets can be successfully delivered to the higher layers in the correct order. To emulate an unreliable channel, the recei
