  • 2. What is SDN? • Today, routers control themselves, passing messages between them • SDN separates the Control and Data planes • A separate, centralized controller then takes command Control Control Data Data Control Control Data Data Data Data Control Data Data2 © 2013 ADVA Optical Networking.

  • 3. 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 * http://mattsflight.blogspot.com * http://virtualskies.arc.nasa.gov/atm/6. html * flightradar24.co m3 © 2013 ADVA Optical Networking.

  • 4. Benefits of Data Center Interaction • Decades of work have yielded today’s agile core networks • Unfortunately, the information to make intelligent decision resides at higher layers • Problem made worse by today’s flow dominated traffic Gridless Hybrid ROADM EDFA/RAMAN Amp Intelligent MUX Router Coherent Router Receiver Agile Core Network4 © 2013 ADVA Optical Networking.

  • 5. Example of SP Applications • Telefonica I&D – IP Offloading Manager • When traffic exceeds a threshold, an additional link is provisioned New circuit provisioning timeConfigured Threshold Circuit deprovisioning time  49 second bring-upRollback Threshold  4 second teardown  Fully automatic 5 © 2013 ADVA Optical Networking.

  • 6. SDN for Dynamic SP Infrastructure • Provisioning for peak traffic is losing battle, and only getting worse. • Answer is dynamic network infrastructure. Site B Site A Daytime Configuration 2 x 10G 1x 10G  All Offices/Sites working 1x 10G Nighttime Configuration 1x 10G  Backup between A/B  Double the bandwidth Site C* Details to be announced at Internet2 April 2013.6 © 2013 ADVA Optical Networking.

  • 7. Direct vs Indirect Model • How to best extend SDN to transport layer? • Direct control yields most potential benefits at cost of complexity and latency • Indirect control is easier to implement, but limits potential of future appsOrchestration Layer 7 © 2013 ADVA Optical Networking.
