Abstract:	隨著網路技術與規模發展快速，已無法如同以往針對單一設備個別管理，需有一套強而有力的管理機制與架構，協助網路管理者管理網路。另一分面，隨著虛擬機器及雲端運算的興起，以及新網路架構及新網路環境的演進，網路虛擬化需求也跟著水漲船高，網路管理已不再是一、兩個管理者即可勝任。再者，管理者除了同時控管眾多網路設備，賦予使用者不同權限，也需要彈性更動網路架構及網路環境。因此發展適合網路虛擬化架構的網路管理系統，其重要性也隨之增加，而在管理者眾多之環境下，除了網路實體設備與線路之管理外，虛擬設備與線路的管理，甚至於管理者的管理也變成一個重要議題。　　本論文提出虛擬網路之階層式管理系統（Hierarchical Management System of Virtual Network，HMSVN）架構，整合網路虛擬化之架構及階層式網路管理之特性，並將此架構實作在NetFPGA網路開發版上，為企業網路環境或大規模網路提供網路管理解決方案。系統架構主要分成管理中心及被管理設備兩大元件，藉由前端以網頁為基礎之管理介面，搭配後端之被管理設備上NetFPGA相關專案，透過OpenFlow Protocol溝通，完成系統之實作。並藉由實驗確認虛擬網路之間，彼此互相獨立不受影響，也可根據政策（Policy）之制定，精確控管網路流之傳輸，以政策之規範進行網路控管，及確認網路管理系統中，階層式管理架構能讓管理者與實體設備及虛擬網路之間正確互動。With the rapid development of network technology and scale, it is hard to handle each device as the previous management and is needed to have a powerful management system and architecture to help network administrators manage the network. On the other side, with the rise of the virtual machine and cloud computing, and the evolution of the network structure and its environment, the requirement of network virtualization is increasing and network management is no longer a one or two managers can be competent. Furthermore, managers not only control much network equipment in addition to giving users different rights, but also change the network infrastructure and network environment flexibly. Therefore, developing network virtualization framework that suits the network management system, its importance increased; In the numerous administration condition, not only the management of physical and virtual equipment and links be an issue, but also the manager’s management has also become an important issue. This thesis presents the Hierarchical Management System of Virtual Network (HMSVN) architecture, integrated the architecture of network virtualization and the features of hierarchical network management, and implemented on NetFPGA network development platform to provide a solution of network management for enterprise network or large scale network. The system architecture is divided into two major components: managing center and managed device. Managers can control the system through a web-based managing interface and setup NetFPGA on managed devices which communicate through OpenFlow Protocol. There are some experiments to demonstrate the isolation of Virtual Network, including controlling network flows by policies. Finally, a demonstration about hierarchical management architecture shows that it could interaction among managers, devices and Virtual Network in the network management system.
