Network planning designer (mind map)-network architecture (2)

Guide

This series of blog posts belongs to the mind map series. The textbook is a 5-day practice book for network planning designers (Zhu Xiaoping Shi You). Through mind maps, it is convenient for candidates to remember and understand the relevance of knowledge points. It is necessary to understand the knowledge points in depth. Read the original book of 5 days practice for network planners, the second is to learn network architecture, including OSI OSIO S I reference model andTCP/IP TCP/IPT C P / the I P reference model, limited the author's knowledge, there are errors and omissions, Wang pointed out, thank you.
