隨著科技的進步，網路系統更是被廣泛的運用，然而網管人員而如何有效率的去管理網路系統，並取得適當的網路拓樸資訊，是一個非常重要的研究方向，本論文針對嵌入式系統，並且利用SNMP(Simple Network Management Protocol)這個管理協定來達成網路管理與拓樸分析的功能。

由於本系統是以具備LCD且硬體資源較為低階的嵌入式系統作為使用平台，所以選擇使用QT作為開發工具，以便能以較少的資源使用之下，提供一個跨平台且具備使用者圖形界面的系統，此外嵌入式系統可透過無線網路來即時的對網路作管理與監控，大大的提升了網管人員的便利性與即時性。

在本系統中，網段搜尋功能可於指定網段中，搜尋所有的網路裝置，並顯示裝置的基本資料與位置，並且可對單一裝置進行管理與分析，網路拓樸分析功能可以探索內部網路的連接狀態，讓網管人員易於管理，Trap訊息接收功能則是針對異常的網路裝置，讓網管人員可以即時的控管，所有功能皆透過SNMP來完成，以降低系統的負擔。

現今的網路管理系統，大部份都是以桌上型電腦作為平台，並且整合了許多的功能，但對於網管人員反而是造成了使用上的困難，此外管理人員也必須在有電腦時才能使用，本系統提供了網路管理上主要的功能，並可在嵌入式系統中使用，搭配無線網路的運用，可達到隨時隨地都可監控與管理網路系統的能力。

Because of the advance of technology, the Internet has been used widely. In addition, the research direction of how to manage the Internet system by network management workers and access the proper information of network topology are very important. This paper aimed at embedded system and made use of the SNMP (Simple Network Management Protocol) to achieve the functions of Internet management and network topology analysis.

Because this system is equipped with LCD hardware and lower levels of the embedded system as the user platform, it uses QT as a developed tool that offers a system which has cross-platform and users' graphic interfaces. Besides, embedded systems can manage and monitor the Internet synchronously through wireless network which enhances the convenience and synchronicity of Internet management workers.

In this system, Internet-part searching can hunt every Internet device of appointed Internet part and show the profile and location of the device. In addition, it can manage and analyze any single device. Network topology analysis can explore the connection status of intranet in order to be managed easily by Internet management workers. Trap message aims at unusual internet device and is used by Internet management workers to manage immediately. All functions of our system are completed by SNMP in order to lower the burden of the system.

Nowadays there are almost Internet management systems worked on desk-top computers only. However, it causes the difficulty in using the system by Internet management workers. In addition, Internet management workers can use the system exclusively by computer. The system in this study offers the main functions of Internet management which can be used in embedded systems. With the wireless network, the users can manage and monitor the Internet synchronicity.
