Put the three Protocols together for learning because these three protocols are on the same layer. ARP is used to find the MAC address of the Ethernet NIC of the target host, and the IP address carries the message to be sent. The data link layer can get the data transmission information from ARP, and get the data information to be transmitted from the IP address.1. IP
There has been a problem for a long time, everyone is talking about the HTTP protocol, TCP protocol, IP protocol, what is the difference between them, what is the use, no one told me, recently read this "illustrated http" understand some of the film from the bookFirst, understand a transmission stream to expandFor example, HTTP is the first client in the Applicat

Introduction IntroductionThe Protocol buffers is a flexible, efficient, automated mechanism (possibly coding) tool for serializing structural data.Like XML, but smaller, faster, and simpler. You define your structured data, and then you can use the special code generated by the tool to easily use various languages (c + + python java)Read and write your structured da

devices constantly detect the network bus, including the time between pauses. When the first domain (address field) is received, each device is decoded to determine if it is destined for itself. After the last transmission character, a pause of at least 3.5 character time is calibrated to the end of the message. A new message can begin after this pause. The entire message frame must be lost as a continuous flow. If there is a pause time of more than 1.5 characters before the frame completes, th
SMTP is used to deliver e-mail messages on the Internet. Document RFC821 provides all the details of the agreement. But you just have to remember the following-the basic commands and methods of the agreement.
The principle of the protocol is simple. Nothing more than a client computer sending a command to the server, and then the server returns some information to the client computer. The commands sent by the guest room and the server response are s
Introduction
There are many types of caching: Server caching, Third-party caching, browser caching, proxy caching, gateway caching, database caching, and so on. The browser cache is the least expensive because the browser cache relies on the client and consumes almost no server-side resources. Today's summary is also associated with browser caching.
Browser caching must be very familiar, simply that the browser on the disk to the most recent user requested data storage, when we request this page
AJP13 is the directional package protocol. For performance reasons, the binary format is used to transmit readability text. The Web server is connected through a TCP connection and a servlet container. To reduce the cost of process generation sockets, the Web server and the servlet container try to maintain a persistent TCP connection and reuse a connection for multiple request/reply loops. Once a connection is assigned to a specific request, it is no
UDP belongs to the transport layer together with the TCP mentioned earlier.
UDP differs from TCP in that it is a non-connection-oriented protocol, that is, when both parties communicate with each other, they do not need to establish a connection beforehand. So the UDP header saves a lot of fields, and the UDP header is only 8 bytes. The UDP header consists of the following:
The UDP header contains only the source port and destination port, plus th

PPP is one of the most basic protocols in the network. PPP is the main content of this article. First, let's take a look at the basic concepts of the PPP protocol. The Point-to-Point Protocol is a data link layer Protocol designed to transmit data packets between equal units. This link provides full duplex operations and transmits data packets in sequence.

Baidu Encyclopedia Description:Hypertext Transfer Protocol (Http,hypertext Transfer Protocol) is one of the most widely used network protocols on the Internet. All WWW documents must comply with this standard. HTTP was originally designed to provide a way to publish and receive HTML pages. 1960 American Ted Nelson conceived a way to process text messages through a computer called hypertext (hypertext), whic
IP Datagram
IP is the core protocol in the TCP/IP protocol family. All TCP, UDP, ICMP, and IGMP data are transmitted in the IP datagram format. The IP address only provides the best-effort transmission service. If an error occurs, the IP address will lose the data and send an ICMP message to the source. In addition, IP datagram can not be accepted in the sending order.
The IP datagram format is as follows:
