跨層之網路管理系統：以輔仁大學為實例

Abstract

網路管理一直是網路研究一項重要的課題，本文設計實作了一個具跨層管理功能的網管系統，該系統將網路管理者的管理方法與模式，轉換成自動化的管理方式，如此有助於增加網路營運管理的穩定性。一般的管理者自行研發網管系統往往藉由第二層的交換器進行異常的處理，鮮少結合第二層與第三層協同處理，本文中對異常處理，提供跨層管理的功能，如此對於網路環境異質度高的系統，提供了更有效率並更具彈性的作法。經實際上線啟用，證實此系統能更快速處理使用者IP位址使用問題、校內蠕蟲發作及校內外異常連線等問題，並有效節省管理者對其他異常處理判斷的時間。Network management is one of the important issues of network researches. This work investigates and implements a network management system with the following properties: cross-layer design and automatic management. While exceptions occur, most previous management systems rarely take both layer-two and layer-three into consideration at the same time; this work provides cross-layer design solutions which is more efficient and flexible under heterogeneous network environments. After some experiments in practical environments, this system can quickly diagnoses and deal with problems, such as abnormal used IP addresses, worms and unusual connections therefore save managers a lot of time.
