The italic part is a question from the reader After reading Richard Stevens’ TCP/IP Protocol Volume 1: Detailed Explanation for a long time, I feel that it is quite difficult to read. How should I learn what the TCP/IP protocol is really about? What can I do after understanding the TCP/IP protocol? I would appreciate … Read more
Brief Introduction to UDP UDP is a transport layer protocol, sitting in the same layer as the TCP protocol. However, unlike TCP, UDP does not provide features such as timeout retransmission or error retransmission, meaning it is an unreliable protocol. UDP Protocol Header UDP Port Number Many applications require the use of UDP, so it … Read more

TCP/IP Model The TCP/IP protocol model (Transmission Control Protocol/Internet Protocol) consists of a series of network protocols that form the foundation of the Internet and are the core protocols of the Internet. The reference model based on TCP/IP divides protocols into four layers: Link Layer, Network Layer, Transport … Read more
TCP HTTP UDP: All are communication protocols, which are the rules followed during communication. Only when both parties “speak” according to these rules can they understand or serve each other. Relationship Between TCP, HTTP, and UDP: TCP/IP is a suite of protocols, divided into four layers: network interface layer, network layer, transport layer, and application … Read more
1. HTTP (Hypertext Transfer Protocol) Hypertext Transfer Protocol (HTTP) is a simple request-response protocol that typically runs on top of TCP. It specifies what kind of messages a client can send to a server and what kind of responses it can expect. The headers of request and response messages are given in ASCII; while the … Read more

IoT protocols refer to the protocols used for communication and data transmission between devices in an IoT environment. Depending on their functions, IoT protocols can be divided into two main categories: transport protocols and communication protocols. Transport Protocols: Mainly responsible for networking and communication between devices within a subnet, such as Wi-Fi, Ethernet, RFID, NFC … Read more

/ Network Layered Structure / Consider the simplest case: communication between two hosts. At this point, only a single network cable is needed to connect the two, specifying their hardware interfaces, such as both using USB, 10v voltage, and 2.4GHz frequency. This layer is the physical layer, and these specifications are the physical layer protocol. … Read more
Source: https://juejin.cn/user/3931509313252552/postse In communication and IT work, networking is essential, and the most important protocol in the network is TCP. Whether in actual work or in written exams and interviews, you can’t escape TCP. I have read documents related to TCP in the RFC, examined the source code related to TCP in Linux, and looked … Read more
