Peering and Transit Tutorials: Open-IXSDN Umbrella IXP Fabric
•
1 like•907 views
The document discusses the migration of the Toulouse Internet Exchange Point (TouIX) in France to an OpenFlow-based fabric called TouSIX. It describes how traditional IXP switching fabrics have issues with broadcast traffic and limited monitoring/filtering capabilities. The OpenFlow-based TouSIX fabric addresses these by enabling no broadcast traffic, edge filtering, monitoring from the control plane. It also provides redundancy and scalability. The document outlines how TouIX was migrated to the new TouSIX topology using Open vSwitch and OpenFlow 1.3. It invites participation in the TouSIX-Manager open source project and notes future research partnerships.
