Umbrella : a deployable SDN-enabled IXP Switching Fabric

Abstract : Software Defined internet eXchange Points (SDXs) are a promising solution to the long-standing limitations and problems of interdo-main routing. While proposed SDX architectures have improved the scalability of the control plane, these solutions have ignored the underlying fabric upon which they should be deployed. In this paper, we present Umbrella , a software defined interconnection fabric that complements and enhances those architectures. Umbrella is a switching fabric architecture and management approach suitable for the topology of any existing Internet eXchange Point (IXP). Umbrella improves the overall robustness limiting control plane dependency. We validate Umbrella through a real-world deployment on two production IXPs, TouSIX and NSPIXP-3, and demonstrate its use in practice, sharing our experience of the challenges faced.
