specific Embodiment approach 1

[0021] Specific embodiment one: the teaching experiment method of the TCP / IP communication process based on Ethernet of the present embodiment, this method is realized by following device, described device is made up of network bus 20, master node and n slave nodes, master node Connect with n slave nodes on the network bus 20, the master node is the active party of the establishment and termination process of the TCP / IP communication process, that is, perform active opening and active closing of the TCP / IP communication process; n slave nodes are TCP / IP The establishment of the communication process and the passive side of the termination process, that is, to perform passive opening and passive closing, the master node and n slave nodes have the same structure, which are composed of a microprocessor 10, a keyboard 13, an Ethernet controller 11, and an Ethernet interface. Circuit (12), display 14 is formed, and the signal output end of keyboard 13 is connected with the signal in...

specific Embodiment approach 2

[0043] Specific embodiment two: according to the teaching experimental method of the TCP / IP communication process based on Ethernet described in specific embodiment one, in step 102, the step of constructing ARP request message at master node is: master node passes display 14 one by one Prompt to set the hardware type, protocol type, hardware address length, operation type, source physical address, source IP address, and destination IP address, each prompt to input a parameter, waiting to receive the data input by the keyboard 13, and judging whether the input data is legal , if not legal, then prompt to re-input, after the data of prompting are legally input, master node prompts ARP request message construction to be completed through display 14, wherein after correctly inputting destination IP address, the microprocessor 10 of master node will automatically Fill the broadcast address into the Destination Ethernet Address field.

Abstract

The present invention discloses a teaching experiment method of a TCP / IP communication process based on an Ethernet, which relates to a teaching experiment method of establishment of a communication process and a termination process. The present invention solves a problem that a character description and a graphic solution are adopted in the existing teaching to explain an abstract and complicated network protocol, to cause that students are not easy to accept and understand. The present invention prompts a construction on a main node and a destination sub-node and sends various messages of a team work in a TC / IP communication mechanism, a precedence order is that the main node constructs an ARP message, the destination sub-node constructs an ARP / ACK message, the main node constructs a FIN message, the destination sub-node constructs the FIN message after a FIN / ACK message is constructed, the main node constructs the FIN / ACK message, and the communication is terminated. The present invention ensures the students to take part in the TCP / IP communication process, to enable the students to understand and get familiar with TCP / IP establishment and termination processes directly, to understand and master the complicated network protocol quickly. The present invention is suitable for a teaching system of various education institutions.

Description

technical field [0001] The invention relates to a teaching experiment method for establishing and terminating a communication process, in particular to a teaching experiment method for establishing and terminating a TCP / IP communication process based on Ethernet. Background technique [0002] The Internet is currently the most famous, successful and widely connected Internet in the world. It consists of a large number of different types of networks connected by Internet-connected devices. It adopts a free and open network organization method, and uses a unified network communication protocol cluster TCP / IP and a general address system to ensure network intercommunication. As the heart of the Internet - LAN technology, Ethernet is the most widely used. Then, on top of the Ethernet, the process of TCP / IP completing the addressing and data transmission between two network terminals is a process that is automatically completed by the network interconnection device and the netw...
