Show 71 – OpenFlow, SDN, Controllers, VXLAN & Wishing for Fishes

A wide ranging discussion this week following the Applied OpenFlow Symposium on Wednesday and the Network TechFieldDay on Thursday/Friday where we talked about the week and the much argued about purpose of VXLAN.

Probably much more relevant to network engineers, I talk to Ivan Pepelnjak and discuss his conversion to believing in OpenFlow/SDN after he co-hosted the event with me. Big thanks to Marko Milivojevic for being willing to ask questions that the listeners would ask ( It takes a lot of courage to ask questions like he did)

Much fun, and herd discussion occurred.

    Put 3 or 4 super-nerds in a room, turn on the recorder, throw in an MPLS bomb followed by a couple of virtual grenades, a VXLAN mortar and or course the OpenFlow nerve gas and “OpenFlow” gets a new meaning relating to the flow of ideas and opinions. Warning: Nerd level hits 9.5 at times. Great podcast!
