Why is everyone interested in SDN?
Agile, automated, shared infrastructure
Mobile Cloud Big Data Agile enterprise
Provisioning time today
Servers Networking
Customers are looking for • Programmability & automation for
innovation & agility
• Multi-tenancy for sharing infrastructure
• Network services independent of HW, location & topology for flexibility
• Open standards & interoperability for lower CAPEX
• Simpler management & control for lower OPEX

Traditional Model SDN Model
• Problem: Current networking model limits innovation, flexibility, scale & agility
• SDN separates control plane from data plane
• Benefits expected from SDN – Scale and evolve control plane independent of network devices
› Faster innovation
– Programmability of the network: better control/visibility on network traffic › Flexibility & Simplified management
– Network virtualization and service orchestration at a large scale › Scale & Agility for shared infrastructure

2009
• Current version is 1.4 (Aug 13th )
• Enables researchers to run experimental protocols in the campus networks we use every day.
• Vendors do not have to expose the internal workings of their network devices.
• Drive network innovation

Benefits of SDN
• Control plane performance and scalability can be increased independent of CPU and memory limitations of network devices
• Scale-up
• Scale-out
• In-line control protocols can be eliminated entirely, and replaced with centralized control logic
• Sophisticated traffic management and network control can be implemented more easily
• Network device operations are made simpler, and easier to manage
• The network devices potentially become less expensive to build

Dell Active Fabric Automation for high performance & cost savings
recommends fixed form factor switches “as an alternative to chassis-based switch architectures”**
Reduce capital costs up to 70%, operational expense by up to 30%
Traditional chassis-based architectures drive power, cooling, and cost up
Traffic is forced into a multi-tier pattern, adding latency

Traditional and Dell Active Fabric Compared
Core
Aggregation
Access
Scalable Start with minimum Spine and Leaf nodes, add more as needed (up to 8000+ ports)
Supports large layer 2 and Layer 3 networks
Resilient
No spine node carries significant percentage of core traffic (100/n %)
A 16 spine design results in 6.25% traffic loss versus a 50% loss in the case of a centralized two core box solution
Efficient
With a 16 spine design 93.75% total network utilization available on a node failure versus 50% with traditional Dual Chassis core design.
