Today: VM on-boarding is measured in minutes

But… today: multi-tier virtual-system connectivity is measured

in days.John Manville, Cisco IT; The Power of a Programmable

Cloud, OFC 2013 (OM2D.2): “It takes about 5 days from an end-

end point of view to provision something like that (a multi-tier system).” Goal is to “get at least

to sub-one day.”

Our Marist SDN Demo will do this in minutes!

What is OpenFlow ?


Separating the Data Plane from the Control Plane:A Useful Analogy

Dataplane are the roads

Control plane is the navigation

Data plane are switches & ports

Control plane is the CPUor network controller

Packet or Flow Switched?

• Ethernet topologies are packet switched

Statistical link utilization

• OpenFlow topologies (today) are flow switched

Application level network control


Do We Want Distributed or Centralized?

12

• Ethernet topologies were built distributed

Scalable but hard to monitor

• OpenFlow topologies (today) are centralized

Control-data separation forces this model

Strengths of one approach are weaknesses of the otherCentralized is better suited for modern cloud applications

• Strategic that there be an open source Controller

• Industry isn’t breaking vendor lock-in just to create vendor lock-in

• Equipment vendors must not be owners of controller

• ADVA will not build an SDN controller

• ODP is the best candidate• ADVA Optical Networking has

joined and is making contributions

• Aligning our WAN Orchestration with ODP

• Common core technologies• Shared core model & extension • Shared tooling• Common Persistence

Currently, enterprises must contract for over-provisioned fixed capacity to meet the multi-gigabit peaks, which results in costly, underutilized capacity during sustained quiescent periods


The High Cost of Overprovisioning

During the storage or virtual machine migration at the beginning of a cloudburst into the provider cloud, bandwidth of 1 to 10 gigabits per second will generally be required. However, for the remainder of that IaaS instance life-cycle, much lower bandwidth, rarely exceeding 200 megabits per second, is required.

Optical Transport and SDN

• Decades of work have yielded today’s agile core networks

• Unfortunately, the information to make intelligent decisions resides at higher layers

• Problem is made worse by today’s flow dominated traffic

Summary

• Optical network virtualization offers cloud providers &

tenants

high-bandwidth, low-latency connectivity on demand.

• Different models for optical network virtualization exist.

• A compromise between hiding the optical complexity and

exposing the optical topology is required.

• Open approaches based on standardized GMPLS or

emerging OpenFlow technologies are possible.
