    Abstract: 隨著物聯網技術的成熟與興起,不同機器與設備之間的溝通所使用的通訊協定也有了更多的選擇。而當中DDS是一項適合用解決Mission-Critical問題的通訊協定,它有著強大的功能與豐富的QoS策略作選擇,讓DDS這項通訊協定通過參數之設定與策略之應用能對應不同需求與環境。然而,當中參數的設定是否合理、選用的策略是否適當,都需要等到實體機器佈署完成後才能經由測試作確認。
    ;With the rise and develop of Internet of Things, there are much more choices for protocol between machines and devices. Among of all, DDS is suitable for resolving the problem of Mission-Critical. It has multi-functions and different QoS policies so that it could apply to parameter setting and policies accordingly. However, whether parameter setting is reasonable and whether applied policy is suitable should be confirmed after the real machine conducts and is tested.
    Therefore, our research presents a system to emulate the environment under DDS protocol, which could reduce the waste of time and cost caused in a real environment. Users could set parameters in this emulated environment accordingly based on different data flows, frequency of publishing messages, dimensions of message and, several QoS policies in DDS. During the transmission, users could observe and record the related information of hardware and message receiving as well. Finally, this data and information turn out to be a report for users to analyze and study, so as to check whether the setting of parameters could satisfy users’ requirements and constraints
