Introduction: This article aims to discuss knowledge about TCP. Please forgive any inappropriate metaphors. In the fourth year of the Tianqi era of the Ming Dynasty, early morning. As dawn broke, I drove a horse-drawn cart full of goods to the South City Gate, which was the central location for handling goods. A line of … Read more
Currently, there are many network protocols built on the TCP protocol, such as telnet, ssh, ftp, http, etc. These protocols can be roughly divided into two categories based on data throughput: (1) Interactive data types, such as telnet and ssh. These types of protocols usually only do small-scale data exchanges, such as pressing a key … Read more
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

The Data Link Layer Has Three Purposes: To send and receive IP datagrams for the IP module. To send ARP requests and receive ARP responses for the ARP module. To send RARP requests and receive RARP responses. Everyone has heard of IP. As for ARP and RARP, ARP stands for Address Resolution Protocol, which is … Read more
Introduction to ICMP Protocol When there is an error in transmitting IP packets – for example, host unreachable, route unreachable, etc., the ICMP protocol will encapsulate the error information and send it back to the host. This gives the host a chance to handle the error, which is why it is said that protocols built … Read more
Click the “IT Program Circle” above to select “Top Public Account”. Source: Zhang Godan’s Technical Journey Since I learned about the TCP/IP congestion control algorithm last time, I increasingly wanted to delve deeper into some underlying principles of TCP/IP. I searched a lot of information online and found a column by Tao Hui on high-performance … Read more

It includes the IP protocol, ICMP protocol, and TCP protocol. Here are some key points to note: Internet Address: This is the IP address, generally … 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
The TCP/IP technology, considered one of the great inventions of the Internet era, has profoundly impacted today’s world. After nearly a month of study and exploration, I have a basic understanding of TCP/IP. Since TCP/IP operates in kernel mode within the OS, many details are not perceptible to users, leading to some confusion about TCP/IP. … Read more
