The Design And Implementation Of Comprehensive Practical Training System For Network Teaching

Integrated Teaching Laboratory Training Network building is essentially a brand-new, "Enlightened Education" model, should focus on learning ability, practical ability, creativity, communication skills and social adaptability, and teamwork ability. The promotion of humanism and scientific spirit of integration and training to meet the needs of economic and social development, with the capability of independent innovation of high-quality personnel for a national innovation system to provide strong support personnel.According to the national human resources professionals on the market, demand is the largest computer professional graduates, accounting for about 30% of the total demand, network and technical personnel account for 40% of the proportion in the next few years will be Further increase. At present, China's network of practitioners around 400,000 people in the next 10 years, the potential demand for talent should be a conservative estimate of 200 million people more than the average annual demand for talent will not be less than 20 million people. And college graduates often lack the specialized vocational training, lack of practical knowledge and vocational skills, can not take the job. Practical skills to create Web-based acute shortage of labor that many companies have a lot of work to slow down in the future. It can be said that the computer network of vocational education in the spring has come." Comprehensive Practical Training System for Network Teaching " is a national computer network to develop education policy under the guidance of the national universities in close collaboration with the development of innovative and practical teaching of computer network products. "Teaching Training integrated network platform" building on the research and teaching is of great significance, but also for improving the competitiveness of the school and students practical ability, the ability to have a major job of promoting the role of schools to raise awareness of the great Benefits.The system can be set up for the school's computer network system for teaching experiment, the experimental basis for an agreement concerning the network, application server configuration, network equipment, Internet technology, network equipment, technical configuration, network equipment, communication protocol between the working principle, the network operating system installation and Configuration, application server installation and configuration, network management, network troubleshooting and network equipment and other safety aspects. The system is operated in practice and theoretical analysis of the experimental teaching unity of the product. A study of knowledge, skills point to start to practice interoperability test, let students access to real equipment, real work environment to learn, hands-on practice so as to enhance the capacity. The next step is to "from external to internal" Theoretical Analysis of the experiment, it is a distillation of the practice of operational test and improve the students to analyze and solve problems.Of the system by teaching management module, test module theory and practice modules. Practice modules H3C network equipment. Teaching management module is the teachers and students, "education" and "learning" the cross-platform, is the theory and practice of experimental module module device management platform. Experiment Module is the theory students learn knowledge and application of experimental platform. Practice is the module to operate equipment and the real solution to the case requested by the platform, but also the completion of the design and synthesis of quasi-experimental type of platform.The system's software experiment by teaching management information systems, integrated network teaching platform for experiments, laboratory-assisted software tool set, and other components.Experimental teaching management information systems and networks to adopt an integrated teaching experiment platform is B/S and C/S structure of the combination, the client program to use C++ language, the main host for the experimental data collection and reporting of information, such as operating with the server-side Winsock use of interactive programming. Experimental teaching management information systems and integrated network teaching platform for experiments to achieve the reunification of the Linux and Windows, use JAVA as a development tool, and use of XML technology to achieve cross-platform and good scalability.Experimental auxiliary software tool set is a collection of software group, these software (such as the Protocol Analyzer, information security toolbox), in order to improve performance, we used the C++ language development as a fundamental, underlying driver of the C language using the direct manipulation . Interface part of the Windows operating system for the design, and strive to achieve good availability.Protocol Analyzer to NDIS layer drive-based, real-time network data capture and statistical analysis. Analyzer bypass flows through the receivers to capture card data network, do not send their packets to be totally does not affect the analysis of the network. Analyzer provides more than 100 kinds of network protocol analysis capabilities, users can select the appropriate filter to capture the frame, and it can capture the frame sequence to the storage disk for later analysis or editorial use. And address this, traffic statistics, the distribution agreement, and other functions.In the experiment, network security, the use of virtual machine technology, viruses, Trojan horses or other dangerous technology transformation of control, both to meet the needs of the experiment and ensure the safety of laboratory networks.The system has the following characteristics:1. Case studySelection of the real case for teaching to enhance students practical skills of students at the same time increase the operational experience.2. A complete test systemRelated to TCP / IP protocol-based, computer networking, application server installation and configuration, network management, troubleshooting network and information security, and other computer networks in various areas and at the same time cover the two major mainstream Linux and Windows operating systems.3. The new teaching modelHeuristic will guide the teaching and learning combined with the completion of the course of the experiment is a practical solution to the problem. Through the joint collaboration between people, to develop students awareness of the team.4. Professional, efficient hardwareTo provide real network environment, suitable for a variety of test requirements; no need to change the physical connection to different network topology between the automatic switch.5. Simple to deploy and maintain a small amount ofExperimental platform for innovation and the introduction of virtual machine technology, properly set point, shielding the environment experiment difference. Significantly reduce the preparation time before the experiment and after the experiment of recovery time.6. The "theory systeme" + "practice syeteme", so that teaching the theory and practice of teaching to achieve a balance7. For the characteristics of schools, provision of teaching solutions8. The experiment can be customized, manageable9. To provide academic support experimental experimental teaching management information systemThe system is a set of theoretical and a practical test of teaching, theory and practice to achieve the integration of computer education in colleges and universities to meet the new demands.The advantages of this system are as follows:(1) For schoolIncrease the utilization of existing resources in schools. For there is no network of laboratories in schools, according to the actual situation can invest; have a real laboratory equipment can be less investment in education theory, to make full use of existing equipment.(2) For TeachersComputer network courses from traditional classroom teaching into teaching laboratory, close to the school system, teaching courses to facilitate teaching. Savings in the school curriculum, the teaching ability of teachers to improve teaching standards.The provision of detailed teaching and experimental program to reduce the test time to prepare. A variety of teaching methods, teachers have inspired and learn from the role of teachers to alleviate the pressure.(3) For studentsStudents learn to operate in practice the theory of knowledge, know-only, but also know why, to improve the practice and innovation.The system has been adopted by the Ministry of Education to identify the scientific and technological achievements, the first version has just been launched across the country on more than 10 schools, the students practical ability to raise and train practical talents played a positive role.
