Integration of Data Center Network Technologies VxLAN, BGP, EVPN

Abstract

The implementation of network overlays, such as Virtual eXtensible Local Area Network (VXLAN) as the data plane and Border Gateway Protocol/Ethernet VPN (BGP/EVPN) as the control plane for virtual network distribution[5], plays an important role in the integration of VXLAN BGP EVPN technologies in modern Data Centers, allowing a better flow control over the network. With this regard, the enhancement of dedicated networks, and, furthermore, of switching and routing capabilities has been achieved, thereby reducing the costs of device-by-device implementation and management towards a more centralized, integrated system. This paper presents the new network architecture, along with its related protocols, not only for control plane, but also for data plane, demonstrating the need to replace the traditional network architectures and protocols, such as Spanning Tree Protocol and vPC.
