Implementing Network Programming in C: TCP/IP Protocol In today’s era of the internet, network programming has become an increasingly important skill. The C language, as a crucial tool for system-level programming, is widely used to implement various network applications. In this article, we will explore how to use C for network programming with the TCP/IP … Read more
Hello everyone, today we are going to discuss a topic that is both frustrating and rewarding in the industrial field—how to make the “old gentleman” Modbus and the “modern youth” TCP/IP shake hands and make peace. Last year, while debugging a sewage treatment plant project, I encountered a “generation gap” issue between these two protocols, … Read more
C++ Network Programming: TCP/IP Protocol Stack In modern computer networks, the TCP/IP protocol stack is the cornerstone of Internet communication. It provides a reliable means of communication for applications. In this article, we will delve into the composition of the TCP/IP protocol stack and its basic implementation in C++. 1. Overview of the TCP/IP Protocol … Read more
Introduction In the development of network applications, TCP/IP communication is fundamental for data transmission between clients and servers. However, ensuring the stability and reliability of communication is equally important. When implementing TCP/IP communication in C#, it is necessary to focus not only on sending and receiving data but also on monitoring the connection status in … Read more
Image course, development board –> Taobao store: Wolf FPGA ConsultationWeChat: MyWork666888 QQ group: 543928922 Recently, Wolf published an article on 100G networking titled “FPGA Project: 100G Network Development Sharing”. It is impressive that it can communicate, but the downside is that it only reaches the MAC layer, and the upper network layers are missing. To … Read more
TCP/IP is the foundational protocol of the Internet. Below is a detailed introduction to it: Protocol Layers •Application Layer: Provides application program interfaces for users. Common protocols includeHTTP (Hypertext Transfer Protocol),SMTP (Simple Mail Transfer Protocol),DNS (Domain Name System), etc.HTTP is used for web page transmission between browsers and servers;SMTP is used for sending emails;DNS is … Read more
As a classic communication protocol in industrial automation, Modbus has been widely used globally since its inception in 1979. From the initial serial communication to today’s high-speed Ethernet links, Modbus has undergone technological evolution and expansion, marking a milestone in the field of industrial communication. The Origin of the Protocol: The Beginning of Serial Communication … Read more
SDNCan SDN network architecture replace TCP/IP architecture?1. SDN and NFV differ from traditional routing table selection rules, as they choose forwarding paths through OpenFlow flow tables. Does this mean that routing protocols like OSPF and EIGRP are no longer needed? Can we say that it has replaced the network layer?2. Overlay provides layer 2 flat … Read more
Implementing a Simple Network Chat Room in C In this tutorial, we will create a simple network chat room using the C programming language. This project will demonstrate how to implement communication between a client and a server using socket programming. 1. Development Environment Setup Before we begin, please ensure you have the following development … Read more
The previous article in this series discussed the “Necessity Analysis of Quantum Communication Engineering.” It inferred, through the introduction of two important papers and an analysis of the latest advancements in quantum computing, that public key cryptography will remain sufficiently secure for a considerable period in the future. Therefore, hastily promoting “quantum communication” engineering projects … Read more
