SDN: Networking technology that decouples control plane from data plane
•Control plane: Decides where data traffic is sent
•Data plane: Executes data transfer

Introduction SDN: Networking technology that decouples control plane from data plane • Control plane: Decides where data traffic is sent • Data plane: Executes data transfer API Control Plane Communication Protocol Interface (e.g.,OpenFlow) Data Plane  Software-defined networking allows centralized control of traffic  Controller is abstracted, treats each data packet differently  Network switches no longer need to be programmed individually 3 © 2014 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL

Differences: Traditional vs SDN • SDN suited to anywhere, anytime and any device data access • Traditional network suited to client-server architecture Traditional Network Software-defined Network Dynamics Quickly adapts to changing business needs Policies & Security Network wide policy application needs device-level changes Policy application becomes simplified and consistent Scalability Network scaling is unsustainable after a point due to high complexity Easily scalable due to agile centralized control Device Control 4 Becomes highly complex in multidevice and mobile environment Incomplete control because changes are subject to vendors’ product cycles Vendor-agnostic, control can lie entirely with enterprise © 2014 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL

Key Benefits SDN technology increases network flexibility and improves uptime while lowering operating costs and capex Technical Benefits Virtualizes entire network; simplifies upgrade procedures Agile and flexible in experimenting with new configurations Better security for apps and devices at the lowest level Manageability improves due to greater integration Expedites automation & compliance initiatives Reduced opex, since network is a single programmable entity rather than collection of diverse components Reduced capex, since hardware (routers, switches) must now compete on price 5 © 2014 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL

SDN in Action Partnering with an experienced SDN vendor helps in faster and cheaper implementation with minimal risk to existing processes For a new network deployment Switchbased  Campus: Consistent IT policy enforcement and optimal user experience  Data center: better scalability, easy to integrate with storage SDN Deployment Models Hybrid Combination of overlay and switchbased models 6 Areas where SDN adds value: Overlay For deployment over existing IP network  Cloud: Flexible resource allocation enables rapid provisioning of cloud services © 2014 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL

Conclusion  SDN: next big thing after ethernet, IP internetworking and wireless LANs  Positive impact on bottom line and on IT/networking risk  Better suited to new technologies: Mobile, Cloud  Existence of legacy systems means market acceptance will take 5-10 years 7 © 2014 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
