网络协议是每个程序员入门的必修课，但是彻底掌握并应用网络协议知识却并非易事，比如常见的TCP/IP、HTTP。网络协议的内容很基础，但基础知识不等于简单知识，更不等于不重要的知识。在网络协议的学习过程中，如果你也有过这样的感受：

• 协议知识琐碎又枯燥，一看书就头大；

• 协议内容很基础，但面试一问就“崩盘”；

• 工作遇到才去查书，现学却没法现卖；

• 协议知识太底层，不知道如何在热门领域应用。

那么，本门课程就是为你量身定制的。

本课程从底层到上层，最基础、最常用、最重要的网络协议进行一一解析，并将深入分析网络协议在云计算、容器和微服务等领域的应用和实践。帮助入门级程序员深入、直观地理解网络协议基础概念和原理，构建一个完整、精准的协议知识框架；帮助有一定工作经验的程序员填补知识漏洞、打通知识体系。

Network protocol is a compulsory course for every programmer, but it is not easy to thoroughly master and apply network protocol knowledge, such as common TCP / IP and HTTP. The content of network protocol is very basic, but basic knowledge is not equal to simple knowledge, let alone unimportant knowledge. In the learning process of network protocol, if you have such feelings:

• The agreement knowledge is trivial and boring, and it is big when you read a book;

  
  

• The content of the agreement is very basic, but it "collapses" as soon as the interview is asked;

  
  

• I only went to look up books when I met with work, but I can't sell them now;

  
  

• The protocol knowledge is too low-level to know how to apply in hot fields.

Well, this course is tailor-made for you.

This course analyzes the most basic, commonly used and important network protocols from the bottom to the top, and will deeply analyze the application and practice of network protocols in the fields of cloud computing, containers and micro services. Help entry-level programmers deeply and intuitively understand the basic concepts and principles of network protocols, and build a complete and accurate protocol knowledge framework; Help programmers with certain work experience to fill knowledge gaps and open up the knowledge system
