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
One, the distinction between communication and communication protocol:1, the traditional meaning of "communication" mainly refers to telephone, telegraph, telex. The "message" of the communication means the messages, and the media messages are passed from one end to the other through the communication network. The content of media message is mainly voice, text, picture and video image. The composition of its network is mainly composed of electronic eq
