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

Networking

(SDN)

• Open: multi-vendor

interoperability

• Modular: scalable,

economical

• Programmable: rapid

provisioning of new services

• Abstraction layer: decouple

hardware/software

• Decouple business applications

• Decouples control plane

• Decouple virtualized configuration Abstraction

• Enable innovation/differentiation

• Accelerate new feature and service introduction

Programmability

• Simplify provisioning

• Optimize performance

• Granular policy management

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

Some Initial SDN Implementations

• Overlay SDN with existing networks

• Sequester new services

• Deploy in own IT organization

14

What Can You Do?

• Expedite: urge your vendors to supply SDN

• Experiment: trial and build your expertise

• Engage: join ONF to drive standards

Drive SDN Standards

Collaborate with the

innovators

Gain visibility in the

community

Influence the future of

networking

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
