John Manville, Cisco IT; The
Power of a Programmable
Cloud, OFC 2013 (OM2D.2): “It
takes about 5 days from an endend point of view to provision
something like that (a multi-tier
system).” Goal is to “get at least
to sub-one day.”

10. Separating the Data Plane from the Control Plane:
A Useful Analogy
Control plane is the CPU
or network controller
Dataplane are the roads
Data plane are switches & ports
Control plane is the navigation

11. Packet or Flow Switched?
• Ethernet topologies are packet
switched
• OpenFlow topologies (today) are
flow switched
Statistical link utilization
Application level network control

12. Do We Want Distributed or Centralized?
• 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 other
Centralized is better suited for modern cloud applications

16. SDN Controller: ODP
• 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

joined and is making

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

19. Cloud Bursting Technologies Require Network
Agility
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.

• Unfortunately, the information to make intelligent decisions resides
at higher layers
• Problem is made worse by today’s flow dominated traffic

43. 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.
