Listen to the Podcast

August 27th, 2012

Rakesh Saha, Director of Product Management for Advanced Technologies at IBM System Networking and Samrat Ganguly, Chief Network Architect for NEC’s ProgrammableFlow join me to help us make sense of the fast paced evolution of Software-Defined Networking and predict its future.

Duration: 12 minutes and 26 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:19 sec: Rakesh, There are a few approaches to SDN including overlay virtual networks, OpenFlow control of physical and virtual switches plus a hybrid. How do you see these implementations evolving over time?

Question 2 @ 5:10 sec: Samrat, There are a range of protocols to use for the overlay of virtual networks to tunnel through physical L2/3 networks, such as GRE, VXLAN , NVGRE, etc. How will this space evolve?

Question 3 @ 6:34 sec: Rakesh, There’s discussion in the industry about how SDN can be used to configure a converged LAN/SAN fabric. Can you talk to this?

Question 4 @ 7:58 sec: Samrat, there are multiple approaches for SDN controllers, be it in a hypervisor, an appliance, part of a cloud stack, etc. How do you see the role of the controller evolving over time?

Question 5 @ 9:17 sec: Rakesh, How do you see SDN evolving and how does programmable networking fit in?

Question 6 @ 10:52 sec: Samrat, same question. How do you see SDN evolving and how does programmable networking fit in?
