If you are a cloud computing provider, soon you might start facing problems with the network part of it. Conventional solutions for network doesn't apply very well for Cloud environments. SDN give us a new way of thinking about network, embracing Inovation. In this session, you will see how Locaweb implemented SDN to solve their network problems after 3 years providing Cloud Solutions in Brazil. A new era for network on the way...

15. OpenFlow
2008 - The OpenFlow Switching specification
was created in 2008 to evangelize and
support OpenFlow. Although hosted at
Stanford University, our goal is for OpenFlow
to be owned by the community – for the
betterment of research and innovation in
networking.

28. Future
• Better network simulations
• Openflow based Routers
• NAT
• Firewall
• DHCP
• Arp proxy
• Security
• Anti-SPAM
• Load Balance

29. Summary
• SDN
o +15% cloud SDN
o 3900 flow/seg (average)
o 6000 flow/seg (peak)
o Low impact implementation
o Physical switches compatibility (Openflow 1.0)
o Better self-demand driven
o Unified Management (API)
