3 What is Software Defined Networking Switch/Router MANAGEMENTPLANE Responsible for managing the device (CLI) CONTROLPLANE Responsible for controlling traffic (IGMP, OSPF ) DATAPLANE Responsible for forwarding traffic (ASIC) 3

4 What is Software Defined Networking Switch/Router MANAGEMENTPLANE CONTROLPLANE DATAPLANE Each device: - Has its own control plane - Has its own management plane - Each device makes its own forwarding decisions 4

5 What is Software Defined Networking Imagine a large network with a lot of devices MANAGEMENTPLANE CONTROLPLANE DATAPLANE 5

6 What is Software Defined Networking Imagine a large network with a lot of devices Inefficient: - Control traffic - Management on each device 6

7 What is Software Defined Networking What if: - We centralize the control plane (decouple from the device) - We centralize the management plane Switch/Router DATAPLANE MANAGEMENTPLANE CONTROLPLANE 7

8 What is Software Defined Networking A single point of configuration and control 8

9 What is Software Defined Networking So what does this give you: - A single point of control of the whole network - A single point of configuration of the whole network - Simplification of the network hardware (lower cost) 9

10 HP definition of software defined networks Following ONF definition 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 Network Network Applications Applications SDN Applications Separate control and data plane; abstract control SDN Controller plane of many devices to one Control & Data Plane Programmable Interface Open standard-based programmatic access to infrastructure Network Device Network Device Network Device 11

11 SDN ARCHITECTURE HP definition of software defined networks SDN architecture built on an open framework APPLICATION SDN Application REpresentational State Transfer aka REST SDN Application SDN Application Open programmable API s CONTROL Virtual Application Networks SDN Controller OpenFlow Open programmable API s INFRASTRUCTURE Network Device Network Device Network Device Network Device 12

12 Virtualization Mode (Hybrid) Allows both Production and OpenFlow VLAN instances A VLAN in Virtualization Mode must be a Member of an OpenFlow Instance APP APP APP CONTROLLER VLAN Management / Controller HP OpenFlow SWITCH VLAN Production VLAN OpenFlow 13
