| Summary: | 碩士 === 國立交通大學 === 網路工程研究所 === 105 === People bring up several shortcomings of 4G mobile network such as high cost, low flexibility, and restricted innovations while the Internet-of-things and AR/VR becoming more and more popular. Software Defined Networking (SDN) and Network Function Virtualization are two popular emerging technologies that possible to solve such problems. However, there are few studies about evaluating virtualized EPC. Most of the studies are about evaluating on one device over virtualization platforms. The results show a gap of network I/O performance between container-based virtualization and native setup.
Network I/O performance is an important metric for the mobile network. This paper evaluates an SDN-based mobile network, Open5GCore, over four different network environments, includes the user plane and control plane tests. These results have shown that the performance of network I/O of Open5GCore for Docker is close to the native setup. There is about 10% overhead for KVM_VirtIO and at most 27% for KVM_rtl8139. The reason for such costs is due to the virtualization techniques have different I/O path and system architecture. The results and analysis are available for network providers.
