Cisco Confidential 1  Goal –Simplify and Streamline Operational Models – Global View and Global Impact –Improved SLAs enhancing the User Experience – “Best Effort”?? –Reduced Capital Expenses based on total network optimization - >60% savings –Increase Service Velocity – Months to Minutes –Allow multi-vendor / multi-domain operation – From a single controller  Today –Network Planning performed in silos –Network Architectures are viewed in Layers –Operations are Layer Focused –When talking about Optimizing it is not about the network but the layer  Requirement –The Network must be treated as ONE, although respect layered expertise –Hide Network Complexity from User © 2013 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 2  Depending on who you talk to –SDN solves all “unsolvable” issues Time Travel Teleportation Extracting sunlight from cucumbers etc…  Realistically –SDN separates Control Plane from Data Plane –Provides lower level abstractions Application drives network Software provides functionality or service constraint to act on lower level abstraction © 2013 Cisco and/or its affiliates.

Cisco Confidential 3  Utilizing Centralized SDN controller to View: control Optical TransportCisco networks Provisioning App • Layered SDN in not enough ONE is key are Technology Resources Capabilities  OpenFlow appears to be the interface Etc. • Flexible NE interfacing is required of choice Router Optical • Hybrid Control is Key  Application drives controller to act on Optical Transport network• A Trusted path to the End Goal is important • Netconf Yang would be preferred  Network elements expose Switching, Treat Xconn, BW.
