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

Listen to the Podcast

September 15th, 2012

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?

Cisco To Offer Campus Slicing via SDN/OpenFlow

Listen to the Podcast

September 15th, 2012

This is the third of a four part podcast series on Cisco’s Open Network Environment or Cisco ONE. Cisco ONE consist of three initiatives; OnePK, Campus Slicing via SDN/OpenFlow and Virtual Overlay. In this podcast I talk with Phil Casini Product line manager for Cisco’s SDN controller development about Cisco’s Campus Slicing functionality thanks to Cisco ONE’s implementation of Software Defined-Networking and OpenFlow.

Duration: 13 minutes 28 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:09 sec: Phil lets start with the Cisco controller and OpenFlow agents. What functionality will the controller have and which Cisco switch families will be equipped with OpenFlow agents?

Question 2 @ 4:54 sec: Is Campus Slicing primarily for the university market or was the design center focused on both academic and enterprise.

Question 3 @ 8:04 sec: Is Cisco’s key added value in Campus Slicing focused on the ability to logically slice a piece of an operational network for researchers to perform their experiments?

Question 4 @ 11:00 sec: What campus slicing use cased do you foresee in the enterprise market?

Cisco’s OnePK Opens up Networking to Programming

Kevin Woods, Cisco Systems

This is the second of a four part podcast series on Cisco’s Open Network Environment or Cisco ONE. Cisco ONE consist of three initiatives; OnePK, Campus Slicing via SDN/OpenFlow and Virtual Network Overlay. In this podcast I talk with Kevin Woods Director of Product Management at Cisco Systems about Cisco’s OnePK programing environment for developers and its potential impact on networks and business process.

Duration: 13 minutes 20 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:00 sec: Kevin lets first talk about why Cisco is offering OnePK? From the briefing I received its clear that this programming environment had to be in development for a few years, so Cisco must have been hearing this requirement for some time. True?

Question 2 @ 2:44 sec: What drove the decision to expose the network to developers via OnePK?

Question 3 @ 3:45 sec: What kind of network information and control will be exposed to developers and what type of applications will benefit from OnePK?

Question 4 @ 5:47 sec: Is there a Cisco OnePK developer ecosystem in development and how will OnePK applications be supported?

Question 5 @ 7:07 sec: What are the implications for the skill set requirements for your customers who will use onePK?

Question 6 @ 8:36 sec: How does onePK differ from OpenFlow?

Question 7 @ 10:56 sec: Will API verbs be consistent across Cisco’s OSs and when will the OnePK SDK be available?

Cisco on VXLAN For Logically Isolating Virtual Subnets At Scale

Listen to the Podcast

August 6th, 2012

Scalability issues have overcome what VLANs were designed to provide. In multi-tenant cloud computing environments with each tenant having many applications many of which require their own logical network segments, the 4k limit of VLANs does not scale. And as cloud networks grow beyond data centers, logically isolated subnets have to be expanded to include geographic scale. Challenges include application mobility over very large resource pools that cover multiple sites, while ensuring the same consistency and logical network policy constraints. Enter VXLAN, jointly announced last summer by industry heavy-weights Cisco Systems, VMware, Red Hat, Arista and others. Han Yang Senior Product Manager at Cisco Systems joins me to discuss VXLAN in virtual networking and the challenge to logically isolate virtual subnets in highly scalable, multi-tenant data centers.

Lippis Report 195: CiscoLive, GigaOm Structure and IBM DOVE, Oh My

July 2nd, 2012

June could not have been a busier month for the networking industry. Cisco launched Cisco ONE, Cloud Connect and Unified Access at CiscoLive. IBM System Networking launched an SDN stack tied into the IBM PureSystems computing platforms of Expert Integrated Systems. And the folks at GigaOm delivered another great Structure conference that brought in cloud thought leaders. In this Lippis Report Research Note, we highlight some of the more significant June of 2012 announcements.
