Over the last several months, since Cisco announced its Open Network Environment strategy, there has been considerable progress on multiple fronts:
- Early field trials (EFTs) with several Enterprise and Service Provider customers
- Proof-of-concepts (PoCs) and customer feedback providing more insight into use-cases and product evolution
- Several acquisitions have been announced that complement the strategy we outlined
- Our engagement and leadership in all the standards bodies around various aspects of open networking continue to grow
During all of these activities and customer interactions, what stood out was the considerable appetite amongst customers and others to learn about these emerging concepts in a more structured way. They expressed a strong desire to break through some of the hype cycle that has pervaded the industry around some of these topics, causing some degree of confusion. They also asked Cisco to present information in an easily consumable manner.
Given the breadth of our portfolio and the diversity of our customer base, this was a bit of challenge for us. A lot of this information was disbursed across different landing pages, blog sites etc. So we had to take a fresh approach to accede to this request.
Based on efforts over the last several weeks, the team has built two foundational portals that serve the purpose of both information aggregation as well as hopefully a watering hole for knowledge seekers -
The Cisco ONE Knowledge portal: This is a centralized aggregated information repository of all the content that we are generating around the topic of open networking across the portfolio, whether it is more formal and structured, or more informal and social. The information here is organized in a more structured way, based on type of content and the chronology.
Check this out at www.cisco.com/go/one and click on the “Knowledge Portal” tab.
What you will see is some quality content manifest itself over time, as we bring the consolidated efforts from various Cisco thought leaders, customers, analysts etc. and assets including more demos, deployment use-cases, case-studies etc. We are also initiating a series of webcasts on this topic to do a deeper dive on technology topics with roughly a 4-6 week cadence, with Cisco CTOs across various technology groups mostly leading the sessions. The intent is to Educate in a more structured manner. For example, we’re kicking off the first of these Cisco ONE webinars with “An Introduction to OpenStack”. (If you have not registered for the webcast yet, please do so).
We sincerely welcome your feedback on how to continue to improve the content as well as experience with the Cisco ONE knowledge portal.

As expected a lot of talks, sessions and interest this year about the reality of the cloud deployment and hybrid cloud at Gartner DC Las Vegas.
Cisco is now perceived as a very credible player in cloud – In fact a quick electronic poll from the audience during one of the key notes speechs ranked Cisco as the number 2 amongst the vendors.
As a proof point of Cisco influence in the cloud computing evolution, both David Yen , Cisco SVP & GM Data Center Group, and John Manville Cisco SVP , Global Infrastructure for IT, presented Cisco vision and achievement in terms of infrastructure and foundation for cloud : Network programmability , and convergence infrastructure are at the core of the efforts driven by these Cisco executives and solution teams to deliver robust infrastructures for both our customers and Cisco IT organization.
If you are interested to know more about these sessions, stay tuned. I will post in the following days on this same blog the slide decks from David and John ,as well as two short and very interesting videos that I did these days:
-One one hand a short dialog between Giuliano Di Vitantonio, Cisco VP Marketing Data Center and Cloud, and David Yen.
-On the other hand a summary of the presentation by John Manville (see introduction blog from Omar Sultan Living with the Programmable Cloud)
Along the same lines , I also invited a panel of bloggers and tweeps , who attend Gartner DC to share with us their reaction to these presentations and their view on the current challenges faced by the IT organizations.
In this video you will hear from Presidio Steve Kaplan (@ROIdude), VCE Jeramiah Doodley (@jdooley_clt) , Cisco Jason Schroedl (@Jschroedl) and Todd Brannon (@tobranno) .

Now that we covered how LISP Routing works in Part 1 and Part 2 of this series, let dig into some of the things you can do with it. I would suggest you go back and read the first two posts if you are new to LISP since I am not going to cover that material again. So, lets look at three of the most popular use cases: 1) VM mobility, 2) IPv6 migration, and 3) smarter multi-homing. I am going to cover the generic use cases, then wrap with some real-world customer use cases.
Since it seems to be the hottest topic, let start with the mobility solution. From a networking perspective, there are a couple of things that are important with a live migration (ex. VMotion): we want to try and preserve TCP sessions (note: this does not mean “packets don’t get dropped”) and we want to maintain optimal routing (note to server folks: you too care about these things). We would also like global mobility—basically the server admin should be able to move her VM wherever she want and not be constrained by IP addressing considerations.
Let’s build on the scenario we have been using in the prior posts, where we have a host 192.168.1.12 is chatting with a VM 172.16.4.7. Assume that we have gone through the whole map-request/map-reply process, so we have something that looks like this:

So, lets dig into LISP Routing a little more. If you have not done so, I would recommend you read my first post, since I am not going to review the concepts here. In this post, I am going to break things down into three steps: 1) how packets are forwarded (i.e. the data plane operation), 2) how mapping information is propagated (i.e. control plane operation), and 3) how we internetwork with non-LISP locations.
For starters, lets head into the weeds and take a look at the LISP header format. In the last post, I mentioned there is some flexibility in how handles IP addressing. The two examples below show a couple of scenarios: pure IPv4 and a IPv4/IPv6 hybrid:

As the OpenStack Summit in San Diego is about to start, I wanted to look back upon this past year and talk about Cisco’s future with OpenStack.
When first learning about Rackspace and NASA coming together to create OpenStack, we saw an opportunity for Cisco to contribute to an important open source project to build a new platform for cloud computing. Since then, we’ve seen the community grow and more companies get involved to build on OpenStack as a platform for their own cloud services.
During this time, our OpenStack@Cisco team has contributed expertise and code to advance the platform. Working with several other vendors at the Santa Clara design summit in 2011, we started the Quantum networking service as an incubation project which I’m pleased to say has now moved into core with the Folsom release. This project makes networking a first class citizen alongside compute (Nova), and storage (Horizon), representing a significant step forward in how cloud computing platforms are built and operated.
