摘要

因現今企業導入虛擬化技術的普及，使得傳統網路架構更加複雜，為改善並簡化傳統網路架構，本文提出讓傳統網路能夠遷移到SDN網路的建議方法和步驟，並嘗試運用SDN網路整合傳統網路中的防火牆、虛擬化網路和網路監控系統，透過集中管理交換機和虛擬化網路，結合合同(Contract)的設定，達到阻擋和過濾封包的效果，並且也能使用SDN控制器監控整個網路環境。
實務結果顯示，本論文所提出的SDN整合防火牆、虛擬化網路和網路監控系統來達到統一管理之概念能正確運作，有效降低維護設定所需之人工作業和排錯時間，減少管理人員管理企業網路環境的負擔，提升工作的效率。

Due to the popularity of virtualization technology introduced by enterprises today, the traditional network architecture is more complicated. In order to improve and simplify the traditional network architecture, this paper proposes the recommended methods and steps to enable the traditional network to migrate to the SDN network, and try to use the SDN network. It integrates firewalls, virtualized networks and network monitoring systems in traditional networks. Through centralized management of switches and virtualized networks, combined with contract settings, the effect of blocking and filtering packets can be achieved, and SDN can also be used. The controller monitors the entire network environment.
The practical results show that the SDN proposed in this paper integrates firewalls, virtualized networks and network monitoring systems to achieve the concept of unified management can operate correctly, effectively reduce the manual work and troubleshooting time required for maintenance settings, and reduce management personnel management. The burden of the enterprise network environment, improve the efficiency of work.
