Cisco’s Nexus 1000V-based Programmable Virtual Network Overlays

Listen to the Podcast

This is the fourth and last podcast in a four part series on Cisco’s Open Network Environment or Cisco ONE. Cisco ONE utilizes the multi-hypervisor Nexus 1000V virtual switch to create virtual network overlays and will be enabling programmability through programmatic interfaces to its virtual supervisor module (VSM), enabling automation-centric provisioning. To make virtual overlays functionally equivalent to physical data center networks, virtual Layer 4-7 application network and virtual security services are added via its virtualization stack of related protocols and layered products. Gary Kinghorn, Senior Manager, Data Center and Cloud Solution Marketing at Cisco Systems joins me to discuss Cisco’s approach to virtual network overlays.

Duration: 22 minutes and 37 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:36 sec: Gary, would you like to add anything to my virtual network overlay discussion in the intro that’s unique to Cisco?

Question 2 @ 3:45 sec: What are some of the misperceptions that most need to be cleared up?

Question 3 @ 4:42 sec: Gary, you and I talked before about a network virtualization stack early this year, and now the conversation appears to have shifted to this virtual overlay concept. Are these really the same things that Cisco has been talking about for a while? Or what’s different and what’s behind the evolution?

Question 4 @ 7:11 sec: There’s a lot of discussion in the industry now about the virtual switch being a key strategic battleground going forward, and that presumably extends to virtual overlay infrastructures overall. We know that VMware acquiring Nicira gives them an overlay story as well that could lead to competition with Cisco specifically in this area. Is this a “battleground”, and if so, what makes Cisco’s approach different or unique?

Question 5 @ 16:23 sec : Lets talk use cases. When do you go from a physical network to a virtual one, when do you need overlays, and what are the applications that are going to be built on top of these new SDN API’s?

Question 6 @ 18:19 sec: Which use cases does Cisco see as virtual network overlays offering the most value today?

Question 7 @ 20:59 sec: The perception is that a lot of this SDN stuff is really out in the future? When and how do data center architects start to implement Cisco’s virtual network overlays?
