Open-Cloud Computing Platform Design based on Virtually Dedicated Network and Container Interface

Abstract

Companies that perform services based on the data center use server virtualization technology to reduce costs. Most companies use hypervisor-based server virtualization technologies, which require hardware virtualization to handle many I/O and resources at the kernel level. Methods/Statistical analysis: hypervisor-based technology is limited by low speed, which can be resolved by using container-based virtualization technology. However, container-based network also has issues. It is difficult to construct flexible container-based network, and data transmission performance declines if the existing container network interface is used. Findings: To solve these problems, this paper uses SDN Technology and Kubernetes, which is used as a container orchestration system. Furthermore, network configuration is linked with CNI of Kubernetes and virtually dedicated network (VDN) application based on the Open Network Operating System (ONOS) Controller for SDN. In other words, we have developed a new CNI by deleting the overlay network and a virtual bridge used in the existing Kubernetes. The newly developed CNIs are directly connected to the host network for high-performance network operations. Improvements/Applications: The Interconnection of VDN and Kubernetes provides high performance and flexible networking capability. We compare the network performance of the existing CNIs and the newly developed CNI in this paper, which describes the superiority of the new CNI in terms of the measured network throughput results.
