    Abstract: 軟體定義網路(Software Defined Network, SDN)與網路功能虛擬化(Network Functions Virtualization, NFV)的概念被提出後,學界與產業界都爭相投入,但要製作一個具有SDN/NFV實驗環境,是相當需要成本的,因此目前存在許多網路測試平台。網路測試平台內其中一項重要的資源就是Computation node,讓使用者可以作為計算的節點或是做為主機,由於舊有的網路測試平台都是以Hypervisor製作VM來作為Computation node,這樣的虛擬化技術必須載入Guest OS使得每次建立一個虛擬網路都需要很大耗費時間與空間的成本,效率也不佳。
    因此本論文提出以Docker為基礎的Openflow網路測試平台(Docker-based Openflow Network Testbed, DONT),Docker製作Docket container,當作Computation node的資源,而Docket container與前者的VM最大的差別在於,不用再載入Guest OS這樣使得開啟時的效能大幅提升,且執行的效能也比VM來的快速。DONT加入Open vSwitch支援SDN的網路架構,同時也使用Vlan ID隔離各個Slice的資源,且Docker所製作的Docket container同時也能夠當作NFV的一般伺服器,將虛擬化網路功能安裝在上面,例如Apache、Firewall等,因此DONT同時支援SDN與NFV兩個網路技術概念。
    DONT不僅改善了Computation node的製作方式,同時也透過瀏覽器與使用者互動,讓使用者可以繪製拓樸及監控Slice的資源,DONT有別於以往的網路測試平台不同在於,使用者可以直接以圖形化的方式指定每個Slice的資源做操控,加上DONT擁有預約配置Slice與錄製及回放封包的功能,這些功能能夠讓使用者更容易的在DONT上製作實驗,且錄製回放的機制更能讓使用者以不同的面向觀察Slice的資源狀態,以作出不同的決策方式應對,同時以DDoS作為DONT完成之後的測試範例,以驗證本系統能夠承受使用者的網路實驗。
    ;After the concept of SDN (Software Defined Network) and NFV (Network Functions Virtualization) are proposed in the world. Researchers begin to study SDN/NFV but the experiment of SDN/NFV needs many costs of devices so there are many network testbeds proposed literature, currently. The Compute node (CN) is an important resource in network testbed. In the past, network testbed usually makes CN by VM. The VM must loads guest OS but let cost and performance, poorly.
    This paper proposed DONT (Docker-based Openflow Network Testbed, DONT) The CN use Docker Container, Docker Container is different VM, because of it does not load guest OS. Docker Container has good efficiency. DONT use Open vSwitch connects CN and Openflow Controller so DONT can support SDN, Docker Container can be commonly server of NFV. It can install VNF (Virtual Network Function) so DONT can support NFV. In order to user can make experiment easily, DONT support the functions of deployment, interaction and replay.
