Click the “blue text” above to follow us Have you ever encountered a situation where the server inexplicably cannot handle the traffic? Despite having sufficient configuration, it keeps dropping connections. After checking for a long time, you find that the issue lies in HTTP connection handling. Think about it, HTTP connections are like tables in … Read more
Better understand how each version of HTTP works. In the early 1990s, Tim Berners-Lee and his team at CERN worked together to define four fundamental components of the internet: Hypertext document format (HTML) Data transfer protocol (HTTP) A web browser for viewing hypertext (the first browser, WorldWideWeb) A server for transmitting data (an early version … Read more

HTTP proxies are widely used for enhancing network security and efficiency. However, many users focus solely on the convenience they offer, overlooking the potential risks. Five Hidden Risks of HTTP Proxies ① Abuse of Proxy Servers Employees may access illegal websites through proxies, exposing the company to legal risks. For instance, some employees might use … Read more
I’ve seen someone ask this online, so I would like to share my answer. The person asking further elaborated: If I treat the server’s HTML, CSS, images, etc. as files transferred to the client and then assemble them for display, can I achieve the functionality of a webpage? This is a seemingly simple question that … Read more
Introduction In the previous article, “Common Application Layer Protocols: Analyzing HTTP from a Traffic Perspective (Part 2),” we introduced the concept, principles, development history, traffic decoding, and simple analysis methods of the HTTP protocol from a traffic analysis perspective. We also discussed two important metrics: request methods and status codes. Today, we bring you the … Read more
Serialization of String Messages In the previous article, we used the <span>MQTTnet</span> framework to implement an MQTT server, an MQTT publisher process, and an MQTT subscriber process. During the messaging process, we directly passed the string from the console. Since MQTT is an application layer protocol, it is based on TCP for data transmission. We … Read more
MESSAGE QUEUING TELEMETRY TRANSPORTWhat is the “MQTT” Protocol? MQTT (Message Queuing Telemetry Transport) is a standard (ISO/IEC PRF 20922) based on the publish-subscribe paradigm. It operates on top of the TCP/IP protocol and is designed for remote devices with limited hardware capabilities and poor network conditions, making it a publish/subscribe messaging protocol that is lightweight, … 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
In the wave of embodied intelligence, robots are evolving from “programmed mechanical arms” in laboratories to integrated agents of “perception-decision-execution”. In this process, communication protocols act as the robot’s “nervous system”, determining its action precision, collaboration efficiency, and adaptability to various scenarios. The EtherCAT technology represents a core breakthrough in this evolution. Guoxun Chip Micro … Read more
