Improving customer satisfaction on internet services in L-NU using virtualized AAA network architecture

Abstract

This study mainly aims to improve the satisfaction level on internet services in Lyceum-Northwestern University (L-NU). From a traditional network architecture, the researchers made use of a virtualized Authentication, Authorization and Accounting (AAA) network architecture to improve the internet services provided to the students of L-NU. For the methodology of this study, the researchers had to make use of a network lifecycle called Prepare, Plan, Design, Implement, Operate, and Optimize (PPDIOO) and there was also a need to combine both quantitative and qualitative research approach. To make this happen, the researchers had to fulfill the following objectives: a) determine the current network setup of L-NU, b) measure the current satisfaction level of the users, c) design, develop and implement a virtualized AAA network architecture, d) measure the satisfaction level of the users who have used the AAA network setup, and e) compare the measured satisfaction level from the users who used the internet facilities using the traditional network architecture and satisfaction level from users who have used the internet facilities after the implementation of AAA network architecture. As a result, it was found out that the implementation of the new network architecture has significantly improved the internet service level of L-NU which is reflected by a higher customer satisfaction rating. Therefore, the researchers conclude that it is most essential that AAA network architecture be implemented to enterprise type of network setup such as but not limited to education institutions in managing their internet services. Consequently, this kind of network architecture lead to a more effective and more efficient way of managing network resources of an institution or an organization while further improving the satisfaction level. In order to optimize the AAA network architecture and gain more implementation advantages, virtualization technology was used to contain and run numerous operating system instances such as four physical servers into one single physical server which favors to saving resources such as energy, space, money and of which also leads to simplified administration.
