Ivan Pepelnjak (CCIE#1354 Emeritus) has been analyzing OpenFlow technology and SDN ideas (and being pretty vocal about their shortcomings) since March 2011, resulting in a number of high-impact events, including chairing the technical roundtable of first-ever OpenFlow symposium in Silicon Valley in September 2011, various presentations and workshops at Interop, Troopers, RIPE and other regional ISP meetings, on-site SDN workshops for large enterprises and service providers, and vendor-sponsored webinars for NEC (describing their ProgrammableFlow solutions and SDN/OpenFlow in general), VMware (the first technical webinar describing VMware NSX after its launch in August 2013) and Nuage Networks (scalability challenges of overlay virtual networks).
Ivan is the author of several SDN-related books, highly praised webinars, and dozens of OpenFlow and SDN-related technical articles published on his blog.
