Computer network on the wine table

The banquet began.

 

The physical layer is the physical layer;

You need to find the location of the person you want to salute based on the characteristics of different people. This is the IP protocol (Network Layer );

You understand that the actual purpose of toast is to deepen your feelings. This is at the application layer, and the feelings in this wine are the data part of the packets.

 

You and a new brother will give a toast to each other. This is called TCP;

You have given the same good brother a toast for many times and killed him, and he will not give back, this is UDP;

You said to all the people at the table, come, let's get together. This is called broadcast;

You are ordering a toast to the people at this table. This is called a ring.

 

 

You said to this brother, please take care of your first meeting. Could you give me your name and have a toast? This is a SYN message;

The brother said, "Why have you ever known each other and have a drink! This is an ACK packet;

You can see that there are no bubbles in the beer of the other party. No, how can you use tea as beer? This is called data verification.

 

 

A brother came over to give a toast to the leaders on your desk. You said no. The leaders drank too much and could not drink any more. This is called firewall;

A brother came over and said that you had five drinks in 10 minutes and reached my limit. This is called bandwidth;

Besides, I have not yet made a response. I can't drink it now. It's just a little slow. This is called congestion control;

 

You want to give a toast to your best brother, so you first find his desk (network number) and his location (host number );

From preparing toast to toast, this is latency, in which you need to experience pouring wine (sending delay), hitting the cup (transmission delay), and your brother being poured (processing delay) these processes.

 

Finally, you are drunk, and you spit out a place without human resources. This is called a buffer overflow.
