  • 1. Thomas Szyrkowiec, Achim Autenrieth, Paul Gunning, Paul Wright, Andrew Lord, Jörg-Peter Elbers, Alan Lumb PD4.F.1 – Thursday 26th September First Field Demonstration of Cloud Datacenter Workflow Automation Employing Dynamic Optical Transport Network Resources Under OpenStack & OpenFlow Orchestration
  • 2. © 2013 ADVA Optical Networking. All rights reserved. Confidential.22 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 Software-Defined Networking Cloud Services & Big Data

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 Frequency Distribution Comparison Time in Seconds Density 0.0 0.1 0.2 0.3 20 40 60 80 Bandwidth Flexing A-B to A-C A-C to A-B Tail caused by L2 connectivity reconfiguration Time difference due to different ROADM configurations and lightpath routing Bandwidth Flexing finished in ~ 18 sec on average (median: 17.41s)

Confidential.1111 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)
