network protocols

protocol used by this file transfer process is called the FTP protocol. File transfer in FTP establishes two TCP connections, respectively, to the control connection to use when sending a transmission request and to the data connection that is used when the data is actually transferred. Remote login (telnet and SSH) is a feature that logs on to a remote computer and enables programs on that computer to run. Remote logins commonly used telnet and ssh two kinds of

Security Salvatore Sanfilippo, author of Redis, once published the Redis declaration, which mentions Redis to be concise and beautiful. Redis does not do much work at the security level.1. trusted environmentThe Redis security design is based on the premise that "Redis runs in a trusted environment". During t

Open source is already widely used in today's software industry, but does open source mean that users can do whatever they want to do with open source code? The answer is no. Open-source sports also have their own game rules and ethics. Failing to comply with these rules will not only damage the healthy development of the open source movement, but also cause reputational and market losses to violators, and more likely fall into legal disputes and compensation. There are many open-source

A Preliminary Study on WCF-17: the equivalence of WCF data protocols, a preliminary study on wcf-17 protocolsData contract equivalenceFeatures If the client successfully sends data of a certain type to the service or the service successfully sends the data to the client, the receiving end does not necessarily have to send data of this type. The only requirement is that the two types of data protocols sho

OC-Concepts and usage of protocols, oc-concepts of protocols In the previous article, we introduced the class extension in OC: Extend. The protocol in OC is equivalent to the interface (abstract class) in Java, but the name in OC is more vivid, because when we are learning interfaces in Java, it can be seen that the interface is equivalent to a contract (Protocol), marking its implementation class. Of cour

Escape characters in communication protocols and escape characters in communication protocolsEscape characters in communication protocolsPurpose: make the communication content more secure and reliable in the communication protocol.For example: if you need to customize a communication protocol, the most basic thing you need is a frame header and frame tail flag, only the recipient of the communication knows when the communication starts and ends.

The two blues are located on two face-to-face mountains and are preparing to attack the Red Army in the valley. The Red Army can beat any Blue Army, but if the two Blue Army troops launch an attack at the same time, the Red Army will not be able to

DiscardDiscard is probably the simplest persistent connection TCP application layer protocol. It only needs to pay attention to the "message/Data arrival" event in the "Three-half events". The event processing function is as follows: 1: void

This article describes the basic working principles of routers in TCP/IP networks and introduces several functions of IP routers, the static and dynamic routing protocols, as well as the concepts of the internal gateway protocol and the external gateway protocol are given, at the same time, the most common RIP, OSPF, BGP and BGP-4 routing protocols are briefly introduced, and then the design objectives and
