OFC/NFOEC: Software Defined Optical Networks
- 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

- 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

- 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

- 6. SDN for Dynamic SP Infrastructure
• Provisioning for peak traffic is losing battle, and only getting worse.
• Answer is dynamic network infrastructure.

- 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 apps
