3 In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications open standard that enables researchers to run experimental protocols in campus networks. Provides standard hook for researchers to run experiments, without exposing internal working of vendor devices Cisco and/or its affiliates. All rights reserved. 3

6 A way to optimize link utilization in my network enhanced, application driven routing An open solution for VM mobility in the Data-Center A way to reduce the CAPEX of my network and leverage commodity switches A solution to build virtual topologies with optimum multicast forwarding behavior A platform for developing new control planes A solution to automated network configuration and control A means to get assured quality of experience for my cloud service offerings An open solution for customized flow forwarding control in and between Data Centers A solution to build a very large scale layer-2 network Develop solutions at software speeds: I don t want to work with my network vendor or go through lengthy standardization. A means to do traffic engineering without MPLS A means to scale my fixed/mobile gateways and optimize their placement A way to distribute policy/intent, e.g. for DDoS prevention, in the network A way to optimize broadcast TV delivery by optimizing cache placement and cache selection A way to configure my entire network as a whole rather than individual devices A way to build my own security/encryption solution A solution to get a global view of the network topology and state A way to scale my firewalls and load balancers Simplified Operations Enhanced Agility New Business Opportunities 2012 Cisco and/or its affiliates.
