Design And Safety Analysis Of University WLAN

With the continuous development of digital networks, the exchange ofinformation in the school is becoming more frequent, and the construction of acampus wireless LAN is becoming more and more important. The wireless LAN isdeveloped on the basis of a wired network. It has becomes the main campus networktechnology with wide coverage and increasing number of access users today. Oncampus, student dormitories, libraries, school buildings, the administration building,training buildings and canteens are major network coverage area, all of them need toensure good enough network signal. However, in the construction of the campuswireless network, their safety performance is one of the main consideration issues.This topic is based on the design and safety analysis of University WLAN.Therefore, we first need to analyze the mode of transmission of the wireless networkand the topology of the network to build a wireless network as the technical reserves.Secondly, there is a need to study the most commonly used of several WLANstandard, four aspects to analyze a variety of standard safety performance from theservice set identifier, wired equivalent protection, physical address filtering andidentity authentication. And the encryption and decryption process is the placeintruder main invasion in wired equivalent protection. Therefore, the algorithm’sdefects limit the safety performance of the network. So, even the cyclic redundancyalgorithms can guarantee the integrity of the data in the transmitter initial and afterreception, but no opportunity to ensure that the data in the transmission process isreplaced. Always, Network intruders use the above defects to adopt the differentperformance attack.We not only need to the campus site investigation, analysis of the user’s networkrequirements, but also to conduct a detailed analysis of the flow of different locationsin different time periods in the specific construction of universities WLAN process. Itcan ensure that the network has high practical value. In process of selected programs,consider the networking mode, standard selected band divided and reuse, indoor and outdoor signal access points installed, and the selection of the billing certificationsystem is a must.In addition, the campus network security issues are also factors that can’t beignored. The factors related to network intrusion security problems and user security.In the event of an emergency, we also need to consider the formulation of a number ofemergency measures. Finally, build a wireless network for some university combiningthe embodiment of these processes. Then, flow the reflection of the run and the user’sidentify, find some of the network problems, and proposed solutions to theseproblems.
