Preface
Presumably, when you were studying computer networks in college, it was not difficult to learn, especially this course has no formulas, and it is more like a liberal arts. I learned a lot of things and memorized a lot of things, but after finishing the exam, they "returned it to the teacher". To sum up, there are too many knowledge points of network protocol, and I can't remember after learning.
There are a lot of articles about network protocols on the Internet. When I read it, I feel that others are saying very reasonable, and I seem to understand, but I can’t stand the question, and I will find that the general process is understood, but many details are still unknown. There is still a long way to go from being able to understand to being able to truly understand. Every time I feel as if I have learned it, but I still can't get started in practical application. Although many details have been explored, but when I went to apply and debug, I found that there was still no idea. When I look at it, I understand, I play the drum when I ask, and I get confused when I use it.
What I want to share with you today is the dry goods summarized by a big cow who works for Huawei. It solves the problem of everyone’s transition from "people to abandonment". It combines obscure knowledge points with some interesting stories through metaphors. It is easier to help everyone systematically and deeply understand the knowledge points and general workflow of network technology. Through this document, you can understand the real application scenarios of these network protocols on the one hand, and on the other hand, you can further deepen your understanding of network protocols by using cloud computing, containers, and microservices. Due to space limitations, I can't show them all for everyone. For those who need high-definition PDF, I put the method of obtaining it at the end of the article! ! !
Network protocol
- Overview of communication protocol
This chapter talks about the birth of IP addresses. Once a machine has an IP address, it can communicate with other machines in the network environment.
- From the second to the third floor
- Important transport layer
There are two important protocols in the transport layer, one is TCP and the other is UDP. For those who are not engaged in low-level development or application development, these two protocols are most commonly used. During the interview, these two agreements are often asked together.
- Common application layer
Talking about the application layer protocol, start with the most commonly used HTTP.
- Unfamiliar data center
- Network in cloud computing
- Network in container technology
Container is Container, and the other meaning of Container is container. In fact, the idea of a container is to become a container for software delivery. Containers have two characteristics: one is packing and the other is standard.
- Microservice related agreements
- Network protocol knowledge series
- Supporting video lectures (supporting courseware)

Write at the end
The network protocol is the foundation, and it cannot be bypassed. You may think that you can rely on other people's libraries when writing Java programs, so you don't need to care about so many underlying technologies. However, as the number of services is large, the throughput is large. What we care about is no longer just a certain Java application, but to improve the performance of the entire cluster. At this time, network problems will arise. I have to say that if the foundation of our technology is laid, after the latest technology comes out, it will be easy to learn after a short period of time, and we will be able to maintain the ability to learn quickly in the wave of new technologies.
