发送端：发送端每收到一个上层报文都会为其设一个唯一的序列号。收到的大报文进行分段，构造S/R报头，如 REF _Ref371456073 h 图表1所示。构造报头和数据部分连接后，按序从片段号=1的报文开始发送，并设置重传定时器，直到发送完毕。重传定时器截止之前，如果收到了接收端发送的完全确认，即数据分段全部被接收，则清除该该序列号报文的缓存和定时器；如果收到了部分确认则根据部分确认的指示重传丢失的分段；如果定时器截止时还没有收到任何接收端的回

CUdpSocket是为了简化发送，解析UDP 数据报所提供的一个基类。这个类封装了基于SOCK_DGRAM的大部分基本操作。这个类提供两种工作模式，一种是和实际处理UDP 数据报的功能紧耦合，这需要通过继承实现，同时设置workmode 为auto_receive（参见SetWorkdMode），另外一种是直接作为单独对象出现，此时用户需要使用Recv成员函数自己处理数据的接收。-CUdpSocket is to simplify this, the analytical data reported by the UDP with a base class. This type of packaging based SOCK_DGRAM the most basic operation. This provides two types of work, is a practical and UDP data processing function of tight coupling, it needs to achieve through inheritance, as set workmode auto_receive (see SetWorkdMode), the other is directly emerging as a separate object, users need to use this member function since Recv others receiving data processing.
