"One of the technologies Vice President Al Gore is pushing is the information superhighway,

which will link everyone at home or office to everything else—movies and television shows,

shopping services, electronic mail and huge collections of data.“

How Does SDN Fit Into The Data Centre?


SDN in a Single Sentence• The hope/expectation of better efficiency/utilization through

identifying flows of packets and making smarter holistic decisions

• A good analogy would be the Air Traffic Control system

Inside vs Outside the Data Center

Inside Google’s Iowa Data Center Outside Google’s NC Data Center


Inside the Data Center

• Virtualizing Switching• Storage and Compute are virtualized.• Switching is only thing remaining.

• Common Management• Different Vendors• Different Functions• One Control

• Commoditized Routers• Open hardware platform.• Dumb hardware does as told.

Inside Google’s Iowa Data Center


Outside Google’s NC Data Center

Outside the Data Center

• Smarter Transport Switching• More dynamic use• Less overprovisioning

• Common Management• Among Transport Vendors• Among Switch Vendors• Among all equipment in network

• Virtual Sandbox for 3rd Party Apps• Open Layer 1 Transport to innovation.• Ability to host simulaneous sessions.


Virtualization & Programmability


The Promise

• The “SDN” mantra

• The ability of software to program the network’s forwarding plane in real time

Programmability

• Separation of features from HW realization

• For network applications this is NFV

• For resources sharing this is Hypervisor

Virtualization

• Rapid Service Definition and Deployment

• Service Automation

• Viable SW Sources

Service Agility

• Simplified Operations

• Platform Consolidation

• Savings in Application and HW

Reduced Cost


• Function Virtualization• Rework of network

applications to run on arbitrary hardware, independent of custom networking hardware

• Resource Virtualization• Functionality to logically abstract

a single set of network resources and make them usable as independent networks

• Present Mode of Operation• Forwarding Plane is under the

control of embedded control plane and device provisioning

• SDN Mode of Operation• Forwarding Plane is programmable

NetworkHypervisor

Finding the appropriate level of abstraction is key to virtualization

• Direct model envisions SDN API’s placed on every optical switching element

• Exposes SDN Controller to analog complexities of optical network

• Only viable in simple networks

• Overlay model abstracts the optical network and presents it as simple elements to the controller

• Hides analog optical complexities from controller and apps


Virtualization in Optical Networks

SDN Controller A

Resource Virtualization

NetworkHypervisor

Network Hypervisor creates programmable and virtualized optical network

• Overlay model can be extended to abstract the network into multiple networks, for multiple controllers

• Allows tenant controllers to control virtualized slices of the carrier network

• Function Virtualization is not a hot topic in Optical
