网络传输协议TCP与UDP 1.TCP协议 1.1 tcp协议的定义 tcp是面向连接的传输成通信协议,他是基于字节的流式协议,数据传输可靠 1.2 tcp协议的特性 (1).有序性:tcp协议在发送端会给数据包编号,是的接收段能够正切判断数据包的正确次序 (2) .正确性TCP使用checksum函数检查数据包是否损坏,发送接收都会计算校验和 &n...
For datagram sockets, care must be taken not to exceed the maximum IP packet size of the underlying subnets, which is given by the iMaxUdpDg element in the WSADATA structure returned by AfxSocketInit. If the data is too long to pass atomically through the underlying protocol, the error ...
