1 The SDN Revolution: Transforming Next Generation Carrier Networks Rick Bauer, Managing Director Open Networking Foundation

2 Overview An Introduction to Software Defined Networking SDN Value Proposition Introduction to the Open Networking Foundation 2013: The State of SDN 2

3 Drivers for SDN Mobile Computing Cloud Computing On-Demand Services Tsunami of Data 3

4 Why Traditional Networking Isn t the Right Solution for Carrier Clouds Not Cost-Effective CAPEX OPEX Not Agile Enough for On-Demand Time-to-market Rapid service provisioning Not Designed for Virtualization East-west traffic support Bottleneck for server virtualization 4

5 New Networking Approach: SDN Current network equipment design monolithic/tightly integrated Network Apps Custom Control Plane Network Applications OpenFlow Controller Custom Silicon (remember mainframe computers?) Distributed Traffic Forwarders 5

6 API API API API SDN Architecture Open: multi-vendor interoperability Applications Modular: scalable, economical Control Plane Network Operating System Software Defined Networking (SDN) Programmable: rapid provisioning of new services Abstraction layer: decouple hardware/software Data Plane Hardware Abstraction Layer Switching Silicon/HW 6

7 Key SDN Principles Abstraction Decouple business applications Decouples control plane Decouple virtualized configuration Programmability Enable innovation/differentiation Accelerate new feature and service introduction Centralized Intelligence Simplify provisioning Optimize performance Granular policy management 7

8 OpenFlow: Instruction Set for SDN Programmable API that allows external software ( controller ) to control the data path of a switch OpenFlow Controller Programs the network, bypassing conventional L2/L3 protocols Prepopulate or send instructions dynamically SDN Controller (Server Software) OpenFlow Ethernet (or Hypervisor) Switch Control Path OpenFlow Data Path (Hardware) 8

9 SDN in the Network Apps Apps Apps Orchestration Hypervisor OpenFlow Controller Compute & Storage 9 Forwarding Devices

10 Real-World Applications for SDN Enterprise Cloud Carrier VM Migration Distributed Campus Networks Ultra-low Latency Hyperscale Data Centers Disaster Recovery Multi-tenancy On-Demand Network Services Traffic Steering Content Distribution 10

11 Examples of SDN in Carrier Networks Seamless Roaming for 3G/4G/WIFI Mobile Edge Span Public and Private Clouds Service Migration to Cloud Automated provisioning, centralized network view Service Monitoring Content Delivery Services Traffic Steering 11

12 Value of SDN/OpenFlow Traffic Steering Self Provisioning Programmable Network Network Control & Scale Uniform Cloud API Effective delivery of network services Additional revenue opportunity Automation & SLA delivery Automate VM mobility Migration of traditional carrier services to the cloud Cost-effective expansion of mobile services OPEX savings OPEX savings Network scalability/elasticity Reduce TCO 12

13 Some Initial SDN Implementations Overlay SDN with existing networks Sequester new services Deploy in own IT organization 13

14 What Can You Do? Expedite: urge your vendors to supply SDN Experiment: trial and build your expertise Engage: join ONF to drive standards 14

15 Why Join the ONF? Drive SDN Standards Influence the future of networking Collaborate with the innovators Gain visibility in the community 15

16 ONF: Leading the SDN Revolution Founded: March 2011 to standardize and accelerate SDN Global organization: Over 85 member companies Board: Google, Facebook, Yahoo!, Verizon, Deutsche Telekom, NTT Communications, Microsoft, Goldman Sachs Guiding principles: Driven by you architects and users of next-generation networks Standards developed by those closest to implementation Open, interoperable standards based on real-world implementations Run like a Silicon Valley startup company 16
