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...

  11. 11. OpenFlow2008 - 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.
