There are multiple ways in which SDN is being deployed today, with OpenFlow controller- based approaches leading, cited by 33 percent of respondents. 31 percent of respondents said that they were using overlay-based SDN approaches, which include VMware's NSX and Juniper's Contrail. 27 percent of the study's respondents said that they were using an SDN controller with multiple protocols and APIs By Sean Michael Kerner | Apr 2, 2014 http://www.enterprisenetworkingplanet.com/netsp/interop-whats-driving-sdn-today.html Vendor A Vendor C Vendor B Academia Start-up 1 Start-up 2 Start-up n …..
  3. 3. 2014-04-14 3 2014 OpenFlow Korea All Rights Reserved News News News ONF on OpFlex Posted on April 3, 2014 by Dan Pitt ONF Executive Director Dan Pitt offers his thoughts on OpFlex, openness, and the southbound interface. Many people have approached ONF for feedback on Cisco’s announcement of OpFlex. While some are making this a battle between standards, others are simply asking what the role could be for both OpFlex and OpenFlow in SDN. While we’ll have some additional commentary on OpFlex in the days to come, I’d like to share a few thoughts with you now on the importance of being truly “open” and what we see as the essence of SDN. “Open Network Linux” could boost viability of vendor-neutral switches by Jon Brodkin - Apr 4 2014, 10:50am +0900 LAS VEGAS—The Facebook-led Open Compute Project has spent the past year building an “open” switch that can boot nearly any type of networking software, giving customers more alternatives to proprietary switch vendors like Cisco. Intel, Broadcom, Mellanox, and Cumulus Networks jumped on board last November, contributing specifications and software that will bring the project closer to a finished design. They weren’t alone, though: Software-defined networking vendor Big Switch Networks, in January, donated what it calls Open Network Linux (ONL) to the project. http://arstechnica.com/information-technology/2014/04/open-network-linux-could-boost-viability-of-bare-metal- switches/?utm_content=buffer54af9&utm_medium=social&utm_source=linkedin.com&utm_campaign=buffer https://www.opennetworking.org/blog/ 2014 OpenFlow Korea All Rights Reserved ETSI + ONF = SDN4NFV • ONF and ETSI announce strategic collaboration for SDN support of NFV https://www.opennetworking.org/blog/
