- 1. Router Project with NETFPGA By Ali Farahany 1
- 2. Router Layer : Software Based
- 3. Router Layer: Hardware Based
- 4. Difficult to develop, always behind industry Difficult to program, constrained environment Too expensive Long TTM … Custom Hardware
- 5. Software Router PC + Multi-Port NIC Total capacity: Only ~10Gb/s Software Base: Easy to develop Limited Capacity Not Scalable Easy to Upgrade …
- 6. SDN and Open Flow Concepts Implementation
- 7. Traditional Computer Networks Track topology changes, compute routes, install forwarding rules Control plane: Distributed algorithms
- 8. Traditional Computer Networks Collect measurements and configure the equipment Management plane: Human time scale
- 9. Software Defined Networking (SDN) API to the data plane (e.g., OpenFlow) Logically-centralized control Smart, slow

- 15. Link between switches facilitates coordination, fail- over Redundant switches increase system availability, eliminates single point of failure Nodes support redundant links, one to each switch Number of routed channelsTwo dedicated system slots for switching resources ATCA Backplane – Fabric topologies – Dual Star
- 16. Data throughput capacity scales with each added node board, large capacities possible Fabric links are inherently redundant, highly available All system slots are identical. No dedicated hub slots. All slots are hub capable Switching services and managment are distributed across all system slots ATCA Backplane – Fabric topologies – Mesh

Editor's Notes
- Maybe this is a better picture… though need some details of what happens in each plane… like in next slides… or, have both?
