【摘要】：实验作为理论与实践的连接点,对工程领域特别是软件工程有着举足轻重的地位。因而构建一个突破传统受时间、地域等局限的网络化虚拟实验室成为对当前越来越有价值的重要课题。随着大学教改工作的顺利推进,教学过程中更加强调学生动手能力及解决实际问题能力的培养,为学生提供更多的实践、动手机会,在不断的实践、动手过程中提高学生的综合能力。在现有硬件条件不能满足时,建立基于计算机网络资源的“虚拟网络实验室”成为解决件设施不足、教学时空限制、死板以及内容与实际脱节这些现存问题、提高实验教学质量的重要选择。本文提出了一个基于.NET的虚拟网络实验室网络的设计和实现方案,对虚拟实验室平台网络管理设计的关键技术进行了深入的研究,提出了可行的虚拟实验室平台网络管理设计构建方案,并根据方案设计,构建出虚拟网络实验室及相应教学管理系统。系统设计和实现过程基于面向对象的思想,并且采用ASP.NET的框架技术,使本系统的设计思路更加明晰、软件更切合实际需要,“计算机网络虚拟实验室”可以为教师们在教学中提供一个可视化的管理平台,使教师对教学过程与学生交互性更强。虚拟实验室是由计算机生成的一种可以创建和体验虚拟世界的计算机系统,是由以计算机仿真技术为核心的虚拟实验和用于运行虚拟实验的网络结构等构成的实验室。实验系统通过软件模拟的形式实现,为学生提供更多的实践、动手机会,在不断的实践、动手过程中提高学生的综合能力,更加方便的进入实验室进行试验,不必受时间等其他因素的影响,由于整个实验室使用了软件模拟的形式实现所以对于硬件的要求已经降到了最低程度,学生完全可以利用软件环境模拟出真实的大型网络而不必考虑硬件条件的不足,提供学生与教师之间顺畅的交流。网络实验室中提供了丰富而具有针对性的各种文档,用户能够以一种科学的方式学习和实验,以多媒体和网络为标志的新一代信息技术的迅猛发展,网络已渗透到各个领域。网络的共享性为我们提供了一个广阔的教学平台,在这个平台上我们可以实现高度的互动交流。在课程安排上,有些教师要很久才能在上下一次课,学生有疑问就可以通过交流版块来解答问题。在版块的设置上也为教师与学生的交流搭建顺畅的平台,课下第一时间就可方便交流。方便了学生与教师学习资料的下载,这样可以大大提高工作的效能,节省学生和教师的时间。因为学习资料很多都是学生学习中需要的,不必自己上网苦苦寻找合适的学习资料,系统的版块上都会有提供,不会浪费大家宝贵时间。能够懂得如何利用已经学到的知识,已有的工具、软件和查阅资料来解决工作中可能遇到的问题,培养独立分析问题和解决问题的能力。掌握一定的网站构建技术,更好的巩固本科所学的基础和专业知识,为以后的相关研究打下坚实的基础。在使用具有完全等价效果的网络设备模拟器软件,对交换机和路由器指令进行配置操作。这就大大在保证实验质量的前提下,大大降低了实验成本。在网络上提供了丰富而具有针对性的各种文档,用户能够以一种科学的方式学习和实验,并且依托于网络的环境,当用户在使用的过程中遇到不能解决的问题时可以与其他用户一起讨论,更易营造了良好的学习气氛。最后我院对此“计算机网络虚拟实验室”进行了系统评估,并接受了用户可接受性测试,最终投入学院的教学使用,学生反馈满意度高。根据该改革的思路,在计算机虚拟网络实验室方面进行了的探索。一是结合自身的学习的实际体会,根据软硬结合的设计方案。研究探讨出了在实验中的一种软(件)硬(件)相结合的实验方法;二是将这种方法集成到已有的“计算机网络虚拟实验室”软件系统中,供后继学习使用。
[Abstract]:The experiment as a connection point of the theory and practice of engineering, especially in the field of software engineering has a pivotal position. Thus the construction of a breakthrough in the traditional time, geographical limitations of network virtual laboratory has become an important task for the current increasingly valuable. With the university teaching reform work smoothly, more emphasis on the practical ability of students and cultivate the ability to solve practical problems in the teaching process, and provide more practical for students, mobile phone will, in practice, improve the comprehensive ability of students in the process. In the existing hardware can not meet the conditions, based on computer cyber source "virtual network laboratory" has become a solution to the lack of facilities teaching space rigid restrictions, as well as the content and the actual gap of these existing problems, an important choice for improving the quality of experiment teaching. This paper presents a quasi.NET based on virtual network Design and implementation of laboratory network, the key technology of network management platform design of the virtual laboratory conducted in-depth research, put forward the feasible design scheme of virtual laboratory network management platform, and according to the design, building a virtual network laboratory and the corresponding teaching management system. The system design and Realization Based on the object oriented idea. And using the framework of ASP.NET technology, the design ideas of the system more clear, more practical software, computer network virtual laboratory can provide a visual management platform for teachers in teaching, so that teachers and students to the teaching process more interactive. The virtual laboratory is a computer system which can create and experience the virtual world created by the computer, by computer simulation technology as the core of the virtual experiment and used to run A virtual experimental network structure of the laboratory. The experiment system realizes through the software simulation, and provide more practical for students, mobile phone will, in practice, improve the comprehensive ability of students in the process, more convenient access to laboratory tests, not affected by other factors such as time, due to the the use of laboratory simulation software in the form of the hardware requirements have been reduced to the lowest degree, lack of students can use the software to simulate the real environment of large network without considering the hardware condition, smooth communication between students and teachers. The network laboratory provides a rich and has for a variety of documents. The user can in a scientific way of learning and experiment, the rapid development of a new generation of information technology characterized by multimedia and network, the network has penetrated into Every field. Network sharing provides a broad platform for our teaching on this platform, we can realize the interaction of height. In the curriculum, a long time to the next class to some teachers, students have questions can exchange forum to answer the question in the forum settings. Also for teachers and students to build a smooth communication platform, the first class time can facilitate communication. Convenient for students and teachers to download learning materials, which can greatly improve the work efficiency, save time for students and teachers. Many learning materials are needed in the study of the students, do not have their own Internet hard to find suitable learning materials, the forum will provide, don't waste precious time. We can know how to use the acquired knowledge, the existing tools, software and data access to solve May encounter problems in the work of training, ability to analyze and solve problems independently. Grasp the construction technology website, better consolidate undergraduate foundation and professional knowledge, for the future research and lay a solid foundation. Network equipment simulator software has the equivalent effect in the use of the configuration of the switch operation the router and instructions. This greatly under the premise of ensuring the quality, greatly reduce the cost of the experiment. The network has provided a rich and for a variety of documents, the user can in a scientific way of learning and experiment, and rely on the network environment, when the user cannot meet in the process of using solution the problem can be discussed together with other users, to create a good learning atmosphere. Finally in our hospital computer network virtual laboratory "evaluation system , and accepted the acceptance test, finally into college teaching, students' feedback high satisfaction. According to the idea of reform, exploration in the computer virtual network laboratory. One is based on the experiences of their own learning, according to the design scheme of combination of hardware and software. In order to find out a soft. In the experiment of () () hard combined experimental methods; two is this method will be integrated into an existing computer network virtual laboratory software system, for subsequent use.
