unlike a TCP port, the information sent over the UDP port may not reach the receiver. It is similar to sending a letter. It is not necessary that the user has received the letter. Hence, the information that needs to be
TCP and UDP headers have a section for indicating port numbers. Network layer protocols — for instance, the Internet Protocol (IP)— are unaware of what port is in use in a given network connection. In a standard IP header, there is no place to indicate which port the data packet ...
Telnet operates using TCP Port 23 and provides many systems with an unencrypted communications channel for text-based information. It's most common usecase is as an Operations and Management interface (O&AM) for network attached devices; where an administrator will use Telnet to connect via IPv4...
Establishing a TCP connection requires that both the client and server participate in what is known as athree-way handshake. The process can be broken down as follows: A client sends the server a SYN packet—a connection request from its source port to a server’s destination port. ...

其实说HTTP协议可靠协议并不是特别的准确,HTTP的可靠性一部分来自于HTTP协议自身,一部分来自于它所依赖的上层TCP协议。 TCP本身就是一个可靠的传输协议,它的可靠性其实就是来自于三次握手,通过客户端与服务器的沟通来确定是否建立连接,UDP就没这么麻烦,传过去就完事了,我管你收没收到。所以基于这样的因素,TCP就不...
