VDI Provisioning: The Lines Are Blurring
• Demarcation of the Access Edge no longer in the Wiring Closet
• Access edge border now extends within the Enterprise Data Center … the “virtual wiring closet”
• That’s where Virtual Desktop Machines are located
• User sessions are now initiated within the Enterprise Data Center

VDI Provisioning: The Lines Are Blurring
• Controls needs to be applied at Access Edge and within the DataCenter ToR
• Identity, Roles and Mobility pervasive across Campus and DC
• Mapping Identity to Physical Desktop Machine and Virtual Desktop Machine
• Dynamic roles, policies, and identity need to be consistent

Enter Software Defined Networking
• De-Couple Forwarding and Policy Decisions From Network Connectivity and Topology
• Centralized, Consistent Policy and Management Model
• Campus edge to DC server edge and into the mobile carrier edge

Where Are The Deployments?
• Mostly Early Trials• Universities, Enterprise Campus, DC and Cloud
• Building Knowledge, Expertise and Comfort
• But, With Growing Interest…

Challenges
• Lack of Maturity
• Standards Changing/Evolving Quickly
• Limited Silicon Support
• Vendor Commitment
• Lack Of Vendor Interoperability• Controller, Switch, Security, Policy
• The Proverbial Departmental Divide
• Misplaced Expectations
• Demonstrable ROI v/s Existing Vendor Approach

OpenFlow
Technology Adoption Cycle

Looking To the Future – OpenFlow App Store?
• OpenFlow becomes the Android of networking
• OpenFlow and related specifications all available asOpen Source
• Apps for every need – From QoS, to PBR, to Identity and mobility, to multi-tenancy
• ONF becomes the Marketplace for OpenFlow Apps?
• Controller vendors eventually become application developers
