UDP protocol：
UDP protocol defines the port, and each application on the same host needs to specify a unique port number, and stipulates that the packet transmitted in the network must be accompanied by the port information, when the packet arrives at the host, the corresponding application can be found according to the port number. UDP protocol is relatively simple, easy to implement, but it has no confirmation mechanism, the packet once sent, can not know whether the other party received, so the reliability is poor, in order to solve this problem, improve the reliability of the network, TCP protocol was born.

File transfer protocol (FTP) is a set of standard protocols used for file transfer on the network. It works in the seventh layer of OSI model and the fourth layer of TCP model, that is, application layer. It uses TCP instead of UDP for transmission. The client has to go through a "three handshake" process before establishing a connection with the server, Ensure that the connection between client and server is reliable, and is connection oriented, providing reliable guarantee for data transmission.

SMTP is a protocol that provides reliable and efficient e-mail transmission. SMTP is a kind of mail service based on FTP file transfer service, which is mainly used for mail information transmission between systems and providing notification of letters. SMTP is independent of specific transmission subsystem, and only needs reliable and orderly data flow channel support. One of the important characteristics of SMTP is that it can transmit mail across the network, PostVer 0

TCP protocol operations may be divided into three phases. <i>Connection establishment</i> is a multi-step handshake process that establishes a connection before entering the <i>data transfer</i> phase. After data transfer is completed, the <i>connection termination</i> closes the connection and releases all allocated resources. PostVer 0

We could just use the TCP/IP protocol when we transmit data, but then, without the application layer, the content of the data cannot be recognized, and the application layer protocol must be used if the data being transmitted is to be meaningful. HTTP(Hypertext Transfer Protocol) is a protocol that uses TCP to transfer information between two computers, typically a Web server and a client. The client uses the Web browser to make an HTTP request to the Web server, and the Web server sends the requested information to the client. PostVer 0

FTP (File Transfer Protocol) is one of the protocols in TCP / IP protocol group. FTP protocol includes two parts, one is FTP server, the other is FTP client. The FTP server is used to store files, and users can use FTP client to access the resources on the FTP server through FTP protocol.

TCP (Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication Protocol, as defined by RFC 793 of the IETF.

Application layer:

Provide users with a set of common applications, such as e-mail, file transfer access, remote login, etc. Telnet uses telnet protocol to provide interfaces registered on other hosts in the network. Telnet session provides character based virtual terminal. File transfer access FTP uses FTP protocol to provide file copy function between machines in the network.

Transport layer:

Provides communication between applications. Its functions include: first, format information flow; second, provide reliable transmission. In order to realize the latter, the transport layer protocol stipulates that the receiver must send back an acknowledgement, and if the packet is lost, it must be retransmitted.

Network layer:

Responsible for communication between adjacent computers. Its functions include three aspects.

1、 After receiving the request, the packet is loaded into the IP datagram, the header is filled, the path to the destination machine is selected, and then the datagram is sent to the appropriate network interface.

2、 Processing input datagram: first check its legitimacy, and then carry out pathfinding - if the datagram has arrived at the sink, remove the header, and hand over the rest to the appropriate transport protocol; if the datagram has not arrived at the sink, forward the datagram.

3、 Deal with path, flow control, congestion and other issues. PostVer 0
