Two Major Themes: Convergence and Mobility Ethernet 3G / 4G WLAN LAN Data Center The Cloud Seamless User Experience WIRED Information WIRELESS Content Applications 3G / 4G Businesses Are Being Mobilized SDN Can Deliver High Value & Make This a Reality2 © 2012 Extreme Networks, Inc.

  5. 5. 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 Internet “Virtual” John User Traffic User Traffic VDI Session “Physical” John Access Edge Core Network Data Center Data Center Wiring Closet ToR VM Servers5 © 2012 Extreme Networks, Inc.

  6. 6. VDI Provisioning: The Lines Are Blurring • Controls needs to be applied at Access Edge and within the Data Center 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 Internet “Virtual” John User Traffic User Traffic VDI Session “Physical” John Access Edge Core Network Data Center Data Center Wiring Closet ToR VM Servers6 © 2012 Extreme Networks, Inc.

  7. 7. 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 Ethernet 3G / 4G WLAN LAN Data Center The Cloud Software DefinedExperience Seamless User Networking WIRED Information WIRELESS Content Applications 3G / 4G Businesses Are Being Mobilized SDN Can Deliver High Value & Make This a Reality7 © 2012 Extreme Networks, Inc.

  8. 8. Where Are The Deployments? • Mostly Early Trials • Universities, Enterprise Campus, DC and Cloud • Building Knowledge, Expertise and Comfort • But, With Growing Interest…8 © 2012 Extreme Networks, Inc. All rights reserved.
  9. 9. 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 Approach9 © 2012 Extreme Networks, Inc.

  11. 11. Looking To the Future – OpenFlow App Store? • OpenFlow becomes the Android of networking • OpenFlow and related specifications all available as Open 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 developers11 © 2012 Extreme Networks, Inc.
