碩士 === 國立交通大學 === 資訊科學與工程研究所 === 104 === Internet has been an important communication media for our daily life. People seek for information, obtain new knowledge and communicate with others through the internet and it has dramatically changed the way how people live. However, as the computer technology continues to progress, the old network architecture has not been able to handle nowadays complex environment. Under the circumstances that the old network architecture has reached it bound, we should reconstruct the network architecture. We take the NCTU EC building as an example, and we carefully analyzed the existing network architecture. After that we introduces a new streamlined design concept of network design and by discovering the problem and future usage, we come out with a new network architecture design for the NCTU EC building. We evaluated the new architecture through Cisco's packet tracer for basic simulation and the actual deployment of small-scale environment. The results show that it has successfully resolved network problems which were existed in the past. Also a significant reduction is achieved in the time for network manager to deal with network problems and at the same time network performance has a substantial increase.
