具動態拓樸及自動預組態的遠距網路實驗室

遠距實驗室的建置可以為學生帶來便利又彈性的學習方式，以彌補課堂學習的不足，同時遠距實驗室亦可以降低實體實驗室的建置成本，不論對學習者或教學者都有相當程度的助益。網路管理的學習強調理論和實務結合，因此自己動手操作設備完成網路的建置後進行結果的驗證是重要且必需的。雖然遠距網路實驗室的發展已行之多年，但大都侷限於網路路由設備和交換器設定的學習，缺乏系統整合的實驗環境，另外在驗證實習結果上也只是單純的提供Ping的方式去測試網路是否有連結，針對Layer4以上的測試則有所不足。此種方式無法適用在對於需進行Layer 4到Layer 7 的測試驗證和學習。往往會受限於網路實體線路配置，因此在學習上多只能給予固定的網路架構和固定的學習目標，當要更改學習目標時就必需要有管理人員，去改變網路的實體線路連結和相關環境的設定，如此一來對於學習和設備資源應用上亦會造成限制。本研究提出一個學習網路系統整合的學習環境，可以透過控制實驗環境中的電腦進行Laye1~Layer7的測試，且具備動態組態之實驗環境的遠距網路實驗室架構，在此架構下使用者可以透過網頁選擇所要練習的網路拓樸並進行實驗室之預約，系統會自動地去完成該實驗所需的網路架構和基本之環境設定供使用者使用，使用者亦可在實驗途中依照需求隨時透過網頁進行網路架構和學習目標的改變而不需透過管理人員的介入。

A remote network laboratory can provide a convenient and flexible learning environment to the students. It can also compensate the limited resources available in normal classroom. Furthermore, the remote network laboratory can also reduce the cost needed to setup and maintain an ordinary laboratory. It can help both the students and teachers in learning and teaching the network technology because the hand-on experience is very important in the learning process. The concept of remote network laboratory has been addressed for many years. However, most of the remote laboratories developed so far are for studying the routers and switches. Usually the “ping” function is used to verify the correctness of the configuration and setup of the experiment. In this case, it is difficult to study the layer 4 to layer 7 protocols. In addition, the experiments may also be limited by the physical equipment setups and cable connections. The laboratory administrator needs to physically rearrange the equipments and cable connections in order to configure a new experiment. This will limit the usage of the resources. In this thesis, we propose a dynamic configurable remote network laboratory architecture to provide an experiment environment that can let the students perform experiment on layer 1 to layer 7 protocols. In this remote laboratory, the students can register for the available time slot and experiment topic. The underline control system will dynamically configure the equipment connections for the designated experiment at the specified time. The students can also select another experiment when they finished up the current one and the control system can reconfigure accordingly without the intervention of the laboratory administrator.
