Real-time network virtualization based on SDN and Docker container

Cloud computing platform is a data-centric architecture, which utilize virtualization resource scheduling technology to integrate and distribute the processing power of distributed server cluster and other network devices distributed over the network, and uses service-oriented architecture to provide users with highly reliable, highly available, and efficient application data services. Although the cloud platform application based on various requirements has become a research hotspot in cloud computing technology, in some high Real-time requirements application scenarios, the research on how to guarantee the real time performance of cloud platform is few. Compared to traditional resource virtualization such as CPU and memory, Docker only provides a small portion of network resource virtualization. The four network modes provided by Docker officially have a single function, which makes it very difficult to apply to cloud platform scenarios with complex network bandwidth requirements and high real-time requirements. Based on Docker's traditional NAT communication method, this paper proposes a network virtualization solution based on SDN and Docker containers. Through comparison experiments, it is proved that the scheme can guarantee the Real-time performance of the container cloud platform.
