2 Agenda Traditional Networking vs. SDN Intel Open Network Platform (ONP) Introduction SDN Use Cases Future of ONP

3 Traditional Networking Tenant 2 Tenant 3 Tenant 1 Network overlay methods are being introduced to build virtualized infrastructure Each switch must learn the network environment Control plane software doesn t change this state information Multi-tenant environments Increase network complexity (VMs, VSw, EVB, VxLAN, NVGRE) Require frequent network updates which are slow to converge 3 *Other names and brands may be claimed as the property of others

4 More Limitations Lack of real-time visibility into the network Lack of standard way to change traffic flows to Lack of tools to dry run new services Changes to the network are difficult, slow, and risky. 4

5 SDN Network Provides a centralized view of the network Enables network virtualization Reduces capital and operating expenses Unifies control of multi-vendor network equipment Traditional Network SDN Based Network Forwarding Tables, Policy, Topology, Congestion, Discovery Forwarding Tables, Policy, Topology, Congestion, Discovery Forwarding Tables, Policy, Topology, Congestion, Discovery Forwarding Tables Forwarding Tables Forwarding Tables Decision, Policy, Topology, Congestion, Discovery SDN Controller 5

6 Control Interfaces Network lications Northbound API: Describes the area of protocolsupported communication between the controller and applications or higher layer control programs. Key examples: Big Switch Big DB, Cisco ONE PK, Open Daylight SAL Controller Controller Node Top of Rack Switch Node Network liances Node Media Gateways Node Cloud Server Node CDN Node DPI Southbound API: Enables communication between the SDN controller and the network nodes (both physical and virtual switches and routers) so that the router can discover network topology, define network flows and implement requests relayed to it via northbound APIs. Key Examples: OpenFlow, Open vswitch, I2RS, ONS API, Proprietary *Other names and brands may be claimed as the property of others.

7 CapEX 1. Virtualizing network functions on COTS HW 2. Reduce dependency on proprietary comms hardware OpEX 1. Automation 2. Uniformity of the physical network 3. Running production, test, service upgrades on same infrastructure 4. Reduced Energy Consumption Service Revenue 1. New Services 2. Broader ecosystem for faster innovation 3. Faster TTM to deploy new services 4. Targeted services per Geo/Customer Type Intel Confidential
