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
C++ Network Programming: Implementation of TCP/IP Protocol In modern computer networks, the TCP/IP protocol is one of the most important communication protocols. It provides a reliable way for data transmission between different devices. In this article, we will implement a simple TCP client and server using C++ to help beginners understand the basic concepts and … Read more
From: Xia Yu Link: blog.csdn.net/yulyu/article/details/69062288 Image from the internet 0 Introduction Mastering TCP/IP and proficiently using Sockets for network programming. Seeing this sentence, does it feel familiar? Many people have encountered this requirement when submitting their resumes, and many might think that such knowledge is generally unnecessary in actual development, thus dismissing it. However, the … Read more
Click on the above “Programmer Interview Circle“, select “Pin or Star“ Grow Together with You～ Next, I want to systematically review the TCP/IP protocol suite. Of course, most of this was learned in college, but as the saying goes, it’s essential to revisit the basics from time to time. The upcoming blogs will all be … Read more
Recently, there was a project where the client’s network environment was unstable, occasionally resulting in packet loss and network jitter, causing our software client to intermittently disconnect from the server, which disrupted ongoing video conferences. This article takes this opportunity to explain in detail the heartbeat mechanism, packet loss retransmission mechanism, and other related content … Read more
1 TCP/IP 1.1 Definition of TCP/IP TCP/IP is a suite of protocols, also known as the Internet Protocol Suite. Computers can only communicate by adhering to these rules. TCP and IP are just two of the important protocols, which is why the suite is named TCP/IP. It actually consists of four layers of protocols. 1.2 … Read more
The fundamental basis of data communication in today’s IP networks is the TCP/IP reference model. Today, we will use a PC to access a WEB server to deeply understand the TCP/IP reference model. As the article is quite lengthy, it is recommended to save it for later reading. TCP/IP Reference Model Computer Network: Simply put, … Read more
1. Core Structure of the TCP/IP Four-Layer Model (The most commonly used layered framework in engineering practice, a simplified version of the network protocol stack) Application Layer → Transport Layer → Network Layer → Network Interface Layer 2. Detailed Layer Explanation (From Top Layer to Bottom Layer) 1. Application Layer Core Function: Directly serves applications … Read more
