THREE KEY ELEMENTS
1. PROGRAMMABILITY
• Link between application and network
• Orchestrated activity to optimize performance
• Cross-referenced performance visibility
2. FROM APPLICATION AWARENESS TO APPLICATION FLUENCY
• Network automatically reacts to virtualized workloads
• Dynamic tuning of network traffic handling
3. GLOBAL CONTROL VIEW
• Improve local decisions making
• Export view to application control

WHAT IS SDN TO ALCATEL-LUCENT ENTERPRISE?
• Evolution of our AFN Strategy
• Solving Automation needs Today
• Delivering Standards-based Interfaces:
• Across the entire portfolio – Campus & Data Center
• Investment Protection leveraging software upgrades to deliver
• Enable our Enterprise customers to move to SDN at their own pace
• SDN Technology not currently compelling for majority of Enterprises
• BUT: Enterprises want to know that you’re products will fit into the SDN Framework if/when they may move towards it.
• Providing Practical Use Cases on how SDN can solve issues in today’s Enterprises

NOW IT IS ALL ABOUT AUTOMATION
• Computing is now completely flexible
but the data center network is not
• The network and the applications are
operating effectively in silos
The network today has little awareness
of applications
Virtual application control systems are unaware
of the network
• Any attempt to improve resource utilization
likely delivers a suboptimal result
