Why we need SDN?
Networks are...
The truth about SDN…
§ It is: § A way for applicaTons to consume network services
very quickly, using a fundamentally new operaTonal model
§ It is not:
§ The answer for every networking problem known to mankind
IT’S TIME TO LIFT THE CLOUD OVER
SDN…
SDN OBJECTIVES
Does SDN = = Openflow?
First Step (circa 2011) § SeparaTon of control &
data planes (ONF, OF) § Logical centralizaTon of
control plane
A GOOD FIRST STEP... But.. Does focus on OF as network level API deliver on the promise of SDN?

§ Replace CLI & script driven EMS w/ centralized cloud based management pla^orm
§ Centralized NMS allows for § End-‐2-‐end service configuraTon § Network APIs can be OF, SNMP, XML, Scripts
Does SDN = = Next-‐Gen EMS?
Does Next-gen EMS go far enough to deliver on the promise of SDN?

Does SDN = = TE (Traffic Engineering)?
§ ObjecTve: Run the Network hober § Enhance path computaTon with:
§ End-‐2-‐end Topology & Path costs § ApplicaTon requirements § Time-‐of-‐day requirements
§ Use OF/PCEP to map flows to opTmal paths
Does an off-line TE fully deliver on the promise of SDN?

SDN = = A new approach to networking
§ For the past decades: The NETWORK has been the “product”
§ Now & looking ahead: APPLICATION DELIVERY is the “product”
As application & user needs change, so should our approach to networks…

In Conclusion
§ To deliver business agility, network virtualizaTon & automaTon are becoming the foundaTon for private clouds
§ To support this trend, a new class of modern SDN soluTon is needed § AbstracTon & AutomaTon with full Control & Visibility
§ Policy-‐driven automaTc provisioning
§ Boundary-‐less automaTon across Data Centers & VPN
§ For all virtualized and bare-‐metal workloads
