    • 隨著網路的發展，傳統網路架構已經無法滿足新應用和功能的開發部署，在此前提下，軟體定義網路(SDN)/OpenFlow被提出來解決這一問題。
    本篇論文描述了一種基於目前最新的NetFPGA-CML平台開發的OpenFlow交換器的設計與實現，這一平台的實現彌補了現有可編程平台上擴充空間不足的問題，讓SDN研究者們可以在可編程硬體交換機上做進一步研究。我們還進一步設計了可配置的服務品質(QoS)保障的功能。通過實現QoS調度器，計量表和可調性，我們的平台能提供給SDN控制器更多的訊息，並且允許SDN控制器對硬體交換器進行配置從而保障QoS。我們可配置QoS機制通過展示QoS功能的實現，SDN研究者們可以在我們的平台上實現他們想要的功能。
    我們的平台取得了比其他硬體平台更豐富的功能特性而且擁有更大的研究潛力，另外我們的平台也比擁有相同特性的軟體平台擁有更高的帶寬。

    This thesis described a practical OpenFlow switch designed for the state-of-the-art NetFPGA-CML platform. With implementation of this OpenFlow platform, we provide a more extendable research platform to those OpenFlow researchers who couldn’t extend functions on existing platforms. Moreover, we developed practical extension features to guarantee QoS. With implementation of QoS scheduler, meter table and configurability, our platform achieved more available information and configurability support for OpenFlow controller that makes our platform better than other available programmable hardware platform.
    The finished work achieves that our OpenFlow switch platform is practical as well as has enough ability to extend additional functions and integrates configurable QoS guarantee to researchers. Our work also presents to researchers and users how to realize function what they want.
