SDNCentral ConfidentialVirtualization and CloudAdoption – 60% of allenterprises will have adoptedsome form of cloud computingin 2013 (Gartner), re-engineering the way theyarchitect their infrastructureand orchestrate the networkto deliver applications.Cost Containment – thereis a big network componentto the consolidation andoptimization initiativesundertaken to help scaleIT within budget.Big Data – generating valuefrom all the enterprise data isthe challenge, and it’s onlygoing to get bigger (consider IPTraffic alone is Growing at anAnnual Compound Growth Rateat 29% through 2016 (CiscoVisual Networking Index). Thenetwork will need to be morereliable, resilient and flexible.

    8. 8. Why SDN Is UsedTo Slice up the Network forMore Flexible ConfigurationsDynamically SegregateTopologically-EquivalentNetworks Across a Data CenterScale the Network Beyond theTypical Limits of VLANs(approx. 4,000 today)BenefitsMaximize Utilization of DataCenter Resources: 20-30%Better UseFaster Turnaround Times whenCreating Segregated Networks –Automated APIs Can Be Used toCreate New Networks in MinutesVersus WeeksData Center – Slice Up the Network in Virtualizedand/or Multi-Tenant Environments8Copyright 2013.

    9. 9. Why SDN Is UsedTo Create Location-AgnosticNetworks Across Data CentersTo Create Location-AgnosticNetworks Across RacksTo Leverage VM Mobility andthe Dynamic Reallocation ofResourcesBenefitsSimplified Applications Are MoreResilient, Without ComplicatedCodingImproved Recovery Times inDisastersBetter Use of Resources, as VMsare Transparently Moved toConsolidated WorkloadsData Center – Stretch the Network in a VirtualizedEnvironment9Copyright 2013.

Why SDN Is UsedSpeed TroubleshootingGain VisibilityFor Any Port in a Multi-SwitchDeployment, Without the Useof Multiple, Expensive NetworkPacket Brokers (NPB).BenefitsDramatic Savings: $50-100K per24 to 48 switches in theinfrastructureCost Reductions: Less Overheadin Initial Deployment, No Need toRun Extra Cables from NPBs toEvery SwitchData Center/Campus Access Networks – GainVisibility with Tap Aggregation10Copyright 2013.

Why SDN Is UsedTo Bypass Expensive InspectionDevices When Moving LargeAmounts of Trusted DataProvide Dynamic, YetAuthenticated ProgrammableAccess to Flow-Level Bypass,Using APIs to Network Switchesand RoutersBenefitsSavings: Hundreds of Thousands ofDollars in Unnecessary Investment in10Gbps or 100Gbps L4-7 Firewalls,Load-Balancers and IPS/IDS thatprocess traffic.Maximize Utility of InspectionDevices: Focusing Them on Trafficthat Poses a Risk to the NetworkReduce Operational Expenses:Automate and Orchestrate DeliveryAcross All ResourcesEdge – Dynamic WAN Re-Routing11Copyright 2013.
