First Field Demonstration of Cloud Datacenter
Workflow Automation Employing Dynamic Optical
Transport Network Resources Under OpenStack &
OpenFlow Orchestration

Introduction
• Datacenter tenants and operators exploit
dynamic compute, storage and networking
resource through virtualization within datacenters
• Software-defined Networking (SDN) allows
programmable control of virtual transport network
resources between datacenters
• We extend SDN flexibility to datacenter and
optical transport network resource orchestration
using open source software:
• OpenStack Orchestration
• OpenFlow SDN controller
• We report a PoC field demonstration using
OpenStack and OpenFlow workflow automation of
key use cases

OpenStack – an Open Cloud OS &
Ecosystem
We extended the use of OpenStack from elastic compute, storage & networking
within the datacenter to elastic transport networking between datacenters

Experimental Results
Frequency distribution of provisioning
time. Each use case was repeated 250
times.
Use case
• Bandwidth Flexing (BF)
Lightpath setup
• Bandwidth Steering (BS) –
Reconfiguration of lightpaths
• from A  B to A  C
• from A  C to A  B
• Time includes
• Lightpath teardown (only BS)
• Lightpath setup
(incl. Opt. Power Balancing)
• Layer 2 connectivity detection
• L3 UDP packet transfer

Summary
• We demonstrated the first fully open, SDN-based
orchestration of datacenter and optical transport network
resources over field installed fiber
• Open source software OpenStack and OpenFlow used to
control commercially available optical transport equipment
• Successful workflow automation of key use cases
• It paves the way towards a synthesis of dynamic
datacenter virtualised applications and optical transport
network automation.
• Timing performance is tens of seconds (without
optimization) which is already a major improvement over
typical provisioning time currently (days, months)
