Implementation and Evaluation of VXLAN Gateway-based Data Center Network Virtualization

摘要

To achieve platform-independent network virtualization among multiple service infrastructures in service providers' data centers, we propose hardware gateway-based data center network virtualization architecture where we place a gateway on each service infrastructure and inter-connect them using overlay network virtualization. By considering a type of VXLAN gateway for this architecture, integration method with server virtualization environment and management mechanism for virtual network among service infrastructures, we propose the implementation method of our proposed architecture. We evaluated and confirmed feasibility of the proposed architecture based on our prototype. We also confirmed that the proposed architecture does not have any performance issue on our network throughput measurement evaluation.
