“ This article focuses on the Wi-Fi architecture and TCP/IP protocol implementation of the ESP32-S3. It analyzes the core modules integrated into its 40nm chip, including the RF front end and baseband, details the STA/AP working modes, dissects the STA connection process and data path, and compares the OSI and TCP/IP protocol stack implementations.” 01 … Read more
Author | Unknown Produced by | Automotive Electronics and Software 1. Overview Implementing an Ethernet communication stack in advanced ECUs requires meeting numerous specifications, which involve functionality, configuration, operation, and interfaces with other modules. These specifications aim to ensure the reliability, flexibility, and security of Ethernet communication while meeting the specific needs of automotive electronics … Read more
Stay updated on the latest technology developments and applications, focusing on performance optimization and architectural design. We welcome your attention! 1. Network Layering 1. The relationship between the OSI seven layers and the TCP/IP four layers The OSI model introduces the concepts of services, interfaces, protocols, and layering, while TCP/IP adopts these concepts to establish … Read more
Today, I will share some insights on networks and protocols, particularly when dealing with projects. If a project is deployed using the HTTPS protocol, how can we call HTTP interfaces from the frontend? Conversely, if a project is deployed using the HTTP protocol, how can we call HTTPS interfaces from a webpage?For example, when accessing … Read more
Click the blue text Follow us 1. Overview Ethernet refers to the baseband local area network specification created by Xerox and jointly developed by Xerox, Intel, and DEC. Ethernet uses CSMA/CD (Carrier Sense Multiple Access with Collision Detection) technology and operates at a rate of 10M/S over various types of cables. Ethernet is similar to … Read more
In modern network communication, the TCP/IP protocol stack is one of the most important foundations. It provides a standardized method for communication between computers. In this article, we will delve into how to perform TCP/IP programming using the C language, demonstrating basic client and server implementations through example code. 1. Overview of TCP/IP Protocol Stack … Read more
In this era of data flying everywhere, information is like the stars in the universe, densely packed and countless. So how are these stars connected? What do they rely on? They rely on —network protocols! When it comes to the best partner of network protocols, we must mention the heavyweight of the open-source community —Linux. … Read more
In today’s digital wave, the Internet has become an indispensable part of people’s lives and work. The TCP/IP protocol stack, as the cornerstone of Internet communication, carries the massive data transmission tasks globally. However, this “cornerstone” is not unbreakable; its design flaws and vulnerabilities at various layers are often exploited by hackers, posing potential threats … Read more
Recently, we encountered a project where the client’s network environment was unstable, leading to occasional packet loss and network jitter. This caused our software client to intermittently disconnect from the server, interrupting 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
