图解各种流行的网络协议 All In One

Network protocols are standard methods of transferring data between two computers in a network.

1. HTTP (HyperText Transfer Protocol)
   HTTP is a protocol for fetching resources such as HTML documents.
   It is the foundation of any data exchange on the Web and it is a client-server protocol.

HTTP/1.0
HTTP/1.1

2. HTTP/2
   HTTP/3 is the next major revision of the HTTP.
   It runs on QUIC, a new transport protocol designed for mobile-heavy internet usage.
   It relies on UDP instead of TCP, which enables faster web page responsiveness.
   VR applications demand more bandwidth to render intricate details of a virtual scene and will likely benefit from migrating to HTTP/3 powered by QUIC.

3. HTTP/3
   HTTP/3 is the next major revision of the HTTP.
   It runs on QUIC, a new transport protocol designed for mobile-heavy internet usage.
   It relies on UDP instead of TCP, which enables faster web page responsiveness.
   VR applications demand more bandwidth to render intricate details of a virtual scene and will likely benefit from migrating to HTTP/3 powered by QUIC.

4. HTTPS (HyperText Transfer Protocol Secure)
   HTTPS extends HTTP and uses encryption for secure communications.
   SSL, old version
   TLS, new version

others

• WebSocket
  WebSocket is a protocol that provides full-duplex communications over TCP. Clients establish WebSockets to receive real-time updates from the back-end services. Unlike REST, which always “pulls” data, WebSocket enables data to be “pushed”. Applications, like online gaming, stock trading, and messaging apps leverage WebSocket for real-time communication.

• TCP (Transmission Control Protocol)
  TCP is is designed to send packets across the internet and ensure the successful delivery of data and messages over networks. Many application-layer protocols build on top of TCP.

• UDP (User Datagram Protocol)
  UDP sends packets directly to a target computer, without establishing a connection first. UDP is commonly used in time-sensitive communications where occasionally dropping packets is better than waiting. Voice and video traffic are often sent using this protocol.

• SMTP (Simple Mail Transfer Protocol)
  SMTP is a standard protocol to transfer electronic mail from one user to another.

• FTP (File Transfer Protocol)
  FTP is used to transfer computer files between client and server.
  It has separate connections for the control channel and data channel.
