Throughput Enhancement with Overlay Network Virtualization Using Commodity Devices

Overlay network virtualization provides virtual networks over IP networks. Building virtual networks over IP networks achieves high mobility to realize a multi-tenant network. Although the encapsulation protocol, such as VXLAN, is widely used to implement overlay network virtualization, the encapsulation process degrades throughput. Therefore, we propose to combine NoEncap and Hoverboard model to improve throughput in commodity devices. NoEncap achieves performance enhancement of overlay network virtualization for commodity devices using non-encapsulation but increases the control plane overhead. The Hoverboard model reduces the control plane overhead. This paper presents the evaluation of the throughput enhancement by the proposed method.
