碩士 === 國立彰化師範大學 === 電機工程學系 === 101 === With the advancement of science and technology and vigorous development of internet, the operation mode of enterprises is also changed from the traditional business model to the e-commerce era. Under the premise of cost-down and competition enhancement, more and more enterprises use the virtual private network (VPN) technology to replace the existing international long-distance lines. In addition to advantages of low cost and good redundancy, VPN also has same safety as that of dedicated lines to give enterprises tremendous convenience. However, to achieve rapid information exchange, the required internet equipment becomes more and more. Once the internet is disconnected, it will cause great losses to the enterprises. Therefore, how to manage VPN well is a serious issue to the information management staff with attention. The purpose of this thesis is to reduce implementation costs by proposing a set of system architecture based on Simple Network Management Protocol（SNMP）, which allows enterprises to monitor and manage their VPNs and to build a prototype system for keeping monitoring network equipment. Once abnormal equipment leads to disconnection, the information management staff will be informed through sending a web audible alarm and e-mail to their smart phones so that the network status can always be in hand at any time. The system architecture is easy to operate and it can help other enterprises of similar types to monitor and manage their VPNs effectively so as to make good use of network resources and reduce the possible operating downtime to effectively and promptly solve business network problems.
