It’s been a few months since VMware acquired Nicira and Cisco launched Cisco ONE. But at the sleepy Interop NY show, IBM and HP expanded their SDN portfolios with the addition of SDN controllers. To date, there are just a few firms with controllers, including VMware, Big Switch Networks, Cisco, HP, IBM, NEC and Nebula. VMware put a value on SDN overlay controllers at $1.26B, which peaked the interest of every venture capitalist as well as network executive; so there’s no surprise to see more controllers entering the market. But what’s occurring is that the controller market is segmenting into OpenFlow and Overlay controllers with little to no awareness and/or interoperability between the two control plains. In this Lippis Report Research Note, we examine the new SDN controllers from Cisco, IBM, Big Switch Networks and HP with an analysis of their evolution.
