Elastic online experiment teaching system based on virtualization

Abstract

The invention discloses an elastic online experiment teaching system based on virtualization. The elastic online experiment teaching system based on virtualization comprises one or more computational nodes and a management mode, wherein the computational nodes are used for providing an experiment virtual environment; one or more computational nodes are in both-way junction with the management node respectively; the management mode is used for managing one or more computational nodes. According to the elastic online experiment teaching system based on virtualization disclosed by the invention, through one or more computational nodes for providing the experiment virtual environment and the management node for providing a management function, adaptive layout for an online experimental environment and functions is realized.

Description

technical field [0001] The invention relates to the field of education technology, in particular to a flexible online experimental teaching system based on virtualization. Background technique [0002] The existing experimental teaching system is composed of ordinary computers networked, each user uses one of them, and the operating desktop and applications are all installed on the computer. The administrator of the computer room is responsible for the maintenance of the software and hardware of the network and all computers, and performs system configuration and management for each computer manually or through network management software. [0003] The experimental teaching system is mainly to provide users with an experimental environment, so that theory and experiment can be closely combined, and at the same time, managers can supervise the implementation of the experimental process. Therefore, experimental equipment and experimental teaching play an important role in it....

AI Technical Summary

Problems solved by technology

However, at present, this kind of experimental teaching system has the following disadvantages: (1) Under this decentralized architecture, the administrators are under a lot of pressure in terms of computer room operation and maintenance, such as common computer hard disk failures, and it takes half an hour to troubleshoot and repair , maintaining dozens of computers would take up at least one full-time

It is difficult to effectively back up and manage data that exists on scattered computers

(3) In terms of resource utilization, the CPU and memory resources required by the user for program compilation and web browsing are completely different. The user who is compiling cannot use the remaining resources of the user on the computer before web browsing. The current environment cannot Realize flexible scheduling of resources among multiple computers, and the standard hard disk is usually difficult to make full use of

Therefore, most of the storage and computing resources on the personal computer are wasted. At the same time, under the guidance of the policy of energy saving and emission reduction, the power consumed by the computer room cannot be ignored.

(4) The traditional environment still has low deployment efficiency. Deploying a new teaching computer room requires cloning the operating system and initializing the application software for each computer. Adding a new computer is also inevitable.
