Design Of Training Project And Construction Of Modern Communication Experimental System For Higher Vocational Colleges

Practice teaching plays a decisive role in teaching in the higher occupation collegescommunication technology, experiment and practice training room is an important place forhigh skilled person in Higher Vocational colleges. But the current experimental equipment inhigher vocational colleges are experiment boxes, these devices have great difference in form,progressiveness, stability, safety, operation and maintenance with communication networkequipment. Commercial equipment has been used by some vocational colleges to buildcommunication laboratory, but With the rapid development and progress of the practicalapplication of communication system, some existing equipment is becoming relativelybackward, and some of the equipment has been eliminated in the actual system, that continueto use these devices to continue training the students obviously can’t adapt to the requirementsof society. College students of communication technology specialty in Higher VocationalCollege will still require longer training again after graduation, before working in thecommunication business. In order to improve the situation, This paper studies how to plan andconstruct a based on the actual business communication equipment, modern communicationexperiment system is suitable for the students of experiment and practical training in HigherVocational colleges. The experimental system using Huawei Technologies Company Limitedproduction of the C&C08program-controlled switches, the equipment selection of opticaltransmission Optix155/622H, broadband access MA5600, layer two switches Quidway,S2726, layer three switches Quidway S3728and other equipment, includingprogram-controlled exchange platform, optical transmission platform, broadband accessplatform, data communication platform four experimental platform. The experimental contentsystem can cover the basics of computer communication, routing and switching technology,program-controlled computer communication technology, The basic principle of broadbandaccess network technology, And related equipment installation configuration and maintenanceand repair communication technology professional training course which can provide a placefor students to practice, course design and graduation design, to provide a good environmentfor teachers of scientific research project. This paper also focus on the design ofinteroperability in the save VLAN across different switches, the internal network planning ofsmall enterprises, the comprehensive training project of broadband access platform&opticaltransmission platform, the comprehensive training project of The program-controlledexchange platform&optical transmission platform as an example, expounds how to make thestudents get through these training in project practice ability and innovation ability promotion.The shortcomings of the system has been discussed at the end of this paper, such as problems like not equipped with UPS power supply shortage, redundancy, some differences betweenthe real system.
