Educational Institute Of Jilin Province Campus-Network Design And Performance Optimize

Thesis summary With popularization day by day of network, past education management mode can meet need , era of development more and more already, how to carry on the construction of the educational information system and make the teaching , management of the school reach higher level, become an extremely urgent subject in educational information construction of every education department. Present pedagogy courtyard campus network of Jilin Province is still only a hardware system + elementary mode of the software platform, with the development of lapse and technology of time, no matter the users or the administrators all find, hardware add mode of software can give play to advantage of campus network far also, campus network should be constructed and built in the brand-new educational pattern, and not only depend on the traditional teaching mode. So carry on the design and planning again to pedagogy courtyard campus network of Jilin Province, meet the needs of educational teaching developing and users, seem very essential . The design philosophy of this text is the information network of multimedia [1 ] of new generation structuring the mode of " hardware + software + modern education " on the basis of original pedagogy courtyard campus network of Jilin Province, make Jilin Province pedagogy institute campus network in original teaching (scientific research ) , communication at the main foundation of function, develop toward digitized campus progressively , make it become one and is based on network, from environment (including equipment , classroom etc. ), resource (books , courseware ,etc. ) is to activity (teaching, manage, not handle official business, serve,etc.) informationalized network systems not intellectual, the ones that let the information technology be better served the masses of teachers and students. In addition, while designing and structuring the network system of new generation , have also explained emphatically in the article that passes system optimization, improve security of the network , the schemes of the stability and efficiency and thinking , have advanced and optimized the system followingly from three respects: 1), adopt route realize export scheme promote the performance of the network more because of tactics; Jilin Province institute of education Internet export adopt and ADSL insert public network two way with CERNET (education and scientific research network), the outlet bandwidth of inserting CERNET among them is relatively narrow, because of users' constant increase, visit the public network very slowly, a lot of users have many complaints to this, badly in need of solution, in addition while visiting resources beyond CERNET free address, pay the high expenses. Must choose through open up second export enter Internet even. Not only can raise the speed of joining like this but also can also reduce the international flow of flowing through the education network effectively , reduce the transporting and linking the expenses of the network. Between network planning and construction in institute of education I is it adopt based on tactics route campus network export solution solve above-mentioned problems more to consider. Tactics route (Policy-Based Routing) is an expanded function of the router, it can not merely be based on purpose address to choose the route, can also make according to data source address , data wrap up terms such as being all kinds of choose the route. In studying and using , consider mainly how to choose the route trend according to source address and purpose address. 2), through strengthening the promotion network security to the router and exchanger safely; Because institute of education numerous user have, distort IP address , visit maliciously at will, hacker situation that procedure attacks take place occasionally, so the security of the network system especially needs paying attention to. My main research strengthens the security of the network equipment oneself through limiting visit to network equipment oneself. Promote the security of the network constantly through the rational distribution of the exchanger , router mainly, avoiding various kinds of emergence of the safety factor effective, facilitate network management at the same time. 3), use JDBC database connect pool mechanism, with effective realization optimization and manage, database of resource, With the constant increase of resources in the network of institute of education, systematic visit capacity and data amount will be heightened, it is bringing the enormous pressure to database thereupon since then, the ones that passed to the database were distributed rationally, can raise the stabilities of the database and system greatly . My main research here is based on JDBC norm, use relevant databases to connect the mechanism of the pool, realize that manages resources of the database effectively. Through the realization of above-mentioned technology, systematic performance has been optimized and promoted, realize logic connect and whom physics join to shine upon , improve systematic usability and person who erupt simultaneously more; Is it to different PRI management that logic connect , improve system management intelligent to realize; Realize the dynamic management that logic is connected and physics...
