希望有人回答TCP/IP 的APPLICATION

大小\哥姐弟妹 有东西想问

不知道现在的TCP/IP  protocal layer 的Application protocal 是不是都用UDP to achieve better performance ?
如果是用UDP 这样Appilication protocal 都是provided it's own recovery flow control and congeestion control functionally ?

TCP does Flow Control. TCP requires three packets to set up a socket connection, before any user data can be sent. TCP handles reliability and congestion control.       

UDP does not have an option for flow control

TCP ensures a reliable and ordered delivery of a stream of bytes from user to server or vice versa. UDP is not dedicated to end to end connections and communication does not check readiness of receiver.

The speed for TCP is slower than UDP.        UDP is faster because there is no error-checking for packets.

你追求速度 选UDP
你追求data完整性 选TCP
