網路管理為管理裝置及獲取裝置資訊最重要的機制。本論文使用電信等級網路管理系統OpenNMS 管理佈署在國立宜蘭大學 (即校園環境) 的無線網路基地台。OpenNMS 提供了很多方便的功能，但是OpenNMS 並沒有包含可以設定網路裝置組態的SNMP 功能，所以我們將SNMP 設定以及SNMP 輸入功能整合至OpenNMS。藉由整合的SNMP 功能，當網路裝置發生問題時OpenNMS 便可以設定及重開網路設備。同時為了管理上的方便，新增群組管理功能至系統，將同區域內的設備歸類於同群組，當同群組內設備發生問題時即可在同一時間全部重新啟動。另外在錯誤通知部分，OpenNMS 所使用的電子郵件不能即時的通知管
理者。為了解決此問題，本論文整合二種主動式通知機制 (即簡訊與即時行動郵件)至OpenNMS。當警告事件發生時，OpenNMS 能夠在最短時間發送簡訊或是即時行動郵件通知管理者。最後，本論文針對簡訊及即時行動郵件進行效能分析及成本評估。藉由結果，管理員可以選擇最有效的方式發送通知。

Network management is an important mechanism which is used to manage network devices and obtain status from the devies. This thesis utilizes OpenNMS,which is a well-known and carrier-grade network management system, to managewireless access points (APs) deployde in National Ilan University (i.e., a campus environment). OpenNMS provides many convenient features, but does not include the SNMP set function that is used to configure the network decices. We develop and integrate SNMP set and SNMP input functions into OpenNMS. Through these functions, OpenNMS can configure and restart wireless APs. The wireless APs work within the same region can be classified in the same group. When a problem occurs in a region, the APs with the same group can be restarted at the same tme. Therefore, we also integrate group management function to the OpenNMS. The E-mail notification in OpenNMS does not inform the manager in real time. To solve this problem, we integrate two active notification mechanisms (i.e., short message and PushMail) into OpenNMS .When warning events are happended, OpenNMS sents short message or PushMail to notify the manager. Finally, this thesis analyze the performance and cost of sending short message and PushMail. With the results, managers can select the most effective way to send notifications.
