用UDP实现可靠文件传输



大家都清楚，如果用TCP传输文件的话，是很简单的，根本都不用操心会丢包，除非是网络坏了，就得重来。用UDP的话，因为UDP是不可靠的，所以用它传输文件，要保证不丢包，就得我们自己写额外的代码来保障了-Use UDP to achieve a reliable file transfer we all know that if we use TCP to transfer files, it will be very simple, simply do not have to worry about will be packet loss, unless the network is broken, you must re. If using UDP, since UDP is unreliable, so use it to transfer files, it is necessary to ensure that packet loss, you must write our own extra code to protect the
