以OpenStack建立可擴充式物聯網系統雲端平台

我們運用OpenMTC物聯網平台軟體、結合OpenStack以建置可自動擴展雲端運算平台。本論文以OpenStack為IaaS基礎架構，整合物聯網系統軟體OpenMTC與OpenStack的插件LBaaS(Load Balancer as a Service)，利用OpenStack相關的API指令，控制虛擬機器的開關機與負載平衡成員的加入與刪除，達成自動擴展(auto scaling)物聯網服務的目的。我們使用Jmeter測試軟體，模擬多個連線同時存取所建置的物聯網系統，以測試其效能。透過效能的模擬測試，當NSCL(Network Service Capability Layer)個數增加時，平均回應時間可以有效下降，提升系統的效率，尤其是在同時有許多連線數的情況之下，更能顯著地提升效能，降低平均回應的時間。

This thesis aimed to explore the issues on developing an auto-scalable M2M service on the NCTU OpenStack private cloud (with OpenStack’ load balancer module, LBasS, installed) by using the OpenMTC software platform. For performance evaluation, we adopted the Apache JMeter benchmark program for conducting the stress test. From the simulation results, we could find that the average response time is greatly reduced as the number of NSCLs (Network Service Capability Layer) is increased (i.e., changed from one to eight) gradually.
