Platform Network System Architecture And Design

Along with the dramatically development of the existing society, the network has already been one part of our daily life, the network has also been utilized in the teaching of universities. Almost every universities, middle school and primary school have established their LAN. As one full scale of advanced Higher Career Tech College, SICHUAN Career Tech College owned it's LAN in 2003, and it was put into the operation of teaching information management platform.Though several years'practice in teaching, teachers sincerely felt that the digitalization of the teaching should be focused on the progress management, ie, the coaching plan setting, the content of the teaching, experiment management etc. For the college, it is especially important that, how to strength the usage of mission-driven teaching method in practice. The existing separated theory and experiment teaching method should be changed, to consolidated one-stop methodology. The assessment and evaluation of student's experiment progress and result can be better managed accordingly.In order to realize the emergence of higher career education and teaching progress, to refine the teaching progress through the analysis of the teaching information platform, and to achieve the goal for people education, a new database platform has been established together with the effort of my colleagues, naming college education progress managing information platform. Moreover, what I in charged is to design better and more appropriate network structure of database system, basing on the analysis of the existing basic hardware environment.Firstly, this completed the statistics for the blocks and floors of the campus which needs the network installment, and then designed the campus topology special for Sichuan vocational and technical college in line with the different location and users of each building and the difference of the network computer density. Accordingly, the type of access layer switch and convergence layer switch was ensured. Besides, the pressure of database, server type, number and detailed property were understood according with the character of each sub-module and the demanding volume of the information in the campus. Moreover, the firewall type and model which suitable for the campus have been confirmed together with the colleague who in charges of the network security works, and the traffic control solution has been finalized during the testing, ensuring the fast, reliable and stable operation.After the establishment of the platform which works on in the intranet of the campus, can fully mitigate the lacking of the teaching information management platform situation, and it can better serve our teachers and students during the learning progress. Based on the platform, more and more professional knowledge can be given and learnt, more practical opportunity can be given to the student, which will all be benefit for students future career development.
