本論文目的是以開源軟體實現及驗證Cloud radio access network。5G行動網路即將到來，開源軟體在其中扮演著舉足輕重的角色，它們提供驗證5G構想與演算法的平台。大部分人會使用OpenStack、Docker、OpenAirInterface等開源軟體來實現Cloud-RAN，但不同研究學者建置出來的Cloud-RAN都會有一定程度上的差異。本論文會以Open Stack、Docker、OpenAirInterface、VPN來實作幾種不同的Cloud-RAN架構。我們針對這些架構進行效能測試，藉由測試packet loss、latency、downlink、uplink等數據，來評估不同架構之間的優劣。而根據我們的實驗結果得到，在OpenStack上使用容器化的C-RAN並結合VPN是一個相對靈活的架構，有別於傳統的C-RAN架構建置時間冗長，本論文透過Docker可以讓C-RAN佈建的速度用秒來計算，並透過VPN讓C-RAN可以在任何一個地方使用。對於未來5G環境的建構，本論文提出架構相對可行的解決方案，當中具有挑戰性的地方是我們使用開源軟體的網路架構皆不同，需要深入研究與測試，才能找出最合適的架構。最後本論文提供4種架構與實驗的結果給相關研究人員參考。

This thesis is to verify the different cloud radio access network architectures based on open source software. 5G mobile is coming, andopen source software plays an important role, they provide platform to verify the 5G concept and algorithm. Most researchers will use OpenStack, Docker, OpenAirInterface and other open source software to implement Cloud-RAN, but different researchers to establish the Cloud-RAN will have a certain degree of difference. This thesis will use OpenStack, Docker, OpenAirInterface, VPN to implement the different Cloud-RAN architecture. We evaluate performance for these architectures, assessing the strengths and weaknesses of different architectures by testing packet loss, latency, downlink, and uplink. According to the results of the performance evaluation, the use of containerized Cloud-RAN and combination of VPN on OpenStack is the most flexible architecture, which is different form the traditional C-RAN architecture.For the future 5G environment construction, this thesis proposes a relatively feasible solution architecture.This thesis can make C-RAN be completed in seconds, and the Cloud-RAN can be used in anywhere via VPN. For the future 5G environment construction, this thesis proposes a relatively feasible solution architecture.
