OpenFlow enabled Integrated Routing and Bridging over Ethernet Virtual Private Networks

Abstract

Ethernet Virtual Private Network is an emerging Data Center Interconnect technology, which relies on Multiprotocol BGP and an encapsulation protocol over IP, such as Virtual Extensible LAN. It enables the creation of Layer 2 overlays on top of provider IP networks, which can be interconnected through the symmetric or asymmetric Integrated Routing and Bridging extension. In this work, we present our testbed implementation of these technologies using OpenFlow and we compare the advantages and disadvantages of the symmetric and asymmetric solutions. © 2020 IEEE.
