Enter Software Defined Networking

• De-Couple Forwarding and Policy Decisions From Network Transport and Topology

• Single, Consistent Policy and Management Model

• Campus edge to DC server edge and into the mobile carrier edge

Where Are The Deployments?

• Mostly Early Trials

• Large Universities, Large Enterprise Campus, DC and Cloud

• Across all geographies

• Building Knowledge, Expertise and Comfort

• Solutions still evolving

• Eco-system integration evolving

• But, With Growing Interest…

• Reflecting the growing pain points

Looking To the Future

• OpenFlow becomes the Android of networking

• Open network OS for Ethernet switches and routers

• OpenFlow and related specifications all available as Open Source

• Apps for every need

• From QoS, to PBR, to Identity Management, to Mobility Management, to multi-tenancy and so on

• Controller vendors eventually become application developers

• Apps come in free, premium, and freemium models

• Switch vendors continue to build and sell switches

• Much like phone vendors continue to sell phones

• ONF facilitates the Marketplace for OpenFlow and SDN Apps?
