The Value of Nuage Networks
§ Taking the datacenter as it stands
§ Policy-‐Based Network Auto-‐instan]a]on
§ Virtualizing Networks not islands
§ Within & across Datacenters & branches
ANY APPLICATION, ANY CLOUD, EVERY TIME.
§ SDN Controller § Instantaneous programming of the network
Virtualized Services Controller (VSC)
§ Event-driven automation § Integration of bare-metal assets
Virtual Rou;ng & Switching (VRS)
§ Business/IT policy engine (definition of rules) § Analytics & service templates
