3 What is Software Defined Networking

4 Open Networking Foundation The Open Networking Foundation (ONF) is a non-profit consortium dedicated to the transformation of networking through the development and standardization of a unique architecture called Software-Defined Networking (SDN), which brings direct software programmability to networks worldwide. The mission of the Foundation is to commercialize and promote SDN and the underlying technologies as a disruptive approach to networking that will change how virtually every company with a network operates.

5 Open Networking Foundation on SDN 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 5 Source: opennetworking.org

6 SDN to Achieve Agility Ability to Apply Business Logic to Network Behavior in Dynamic Fashion SDN Architecture Application Layer Control Layer Infrastructure Layer Business Business Applications Applications Business Applications Deliver open programmable interfaces to automate orchestration of network services (e.g. OpenStack, CloudStack) Cloud Orchestration Programmable Open APIs (Northbound) Network Network Applications Applications SDN Applications Separate control and data plane; abstract Network Services control SDN Controller plane of many devices to one Control & Data Plane Programmable Interface (e.g. OpenFlow) Open standard-based programmatic access to infrastructure Network Device Network Device Network Device 6

7 What is the value of Software Defined Networking

8 SDN/Openflow potential Better resource utilization; greater scale, multi-tenancy Adoption of Cloud Services; integration into cloud orchestration frameworks Simplified Management Intelligent automation across infrastructure & applications: common open API s Remove vendor dependencies and product roadmaps.. What are yours..? 8

9 SDN Architecture Simple technology use case Traffic Classification Network Resource Scaling (Firewall/IPS) Efficient Multipathing Application Layer Distributed Load Balancing Application Adaptive Load Sharing Shared Intelligence with Resource Classification Control Layer SDN Controller Infrastructure Layer OpenFlow Switches Network Servers FW/IPS Routers Extends scalability beyond traditional limits Remove traffic bottlenecks Improved resource utilization Standards-based using OpenFlow 9

10 How can Software Defined Networking benefit Research and Education

11 Research and Education History and Benefits History of Open Networking Foundation/Openflow lies inside academia OpenFlow development started in 2007 led by Stanford University and the University of California at Berkeley; Ethane Delivering common infrastructure abstracted for multiple faculty/departments usage Network Development and Deployment Initiative (NDDI)/Open Science, Scholarship and Services Exchange (OS3E) Indiana Center for Network Translational Research and Education (InCNTRE) 11
