Today’s business is more distributed and mobile than ever. Whether companies are building new data centers, redistributing existing servers, or outsourcing IT functions to public, private, and hybrid cloud delivery models, the network is at the center and a key control point for cost-effective cloud services delivery model.
Cloud computing is the most network-centric compute paradigm to date. A successful cloud service offering will depend on a network foundation that’s elastic, agile, and compute workload optimized enabling organizations to transition IT assets to the cloud securely, and cost effectively. Read More »

In the world of fashion, one-size-fits all has very limited appeal. People come in all shapes and sizes, with tastes, preferences, and needs that are equally diverse. So too are the diverse approaches and use cases that are driving interest in Software Defined Networking (SDN), automation, simplification, orchestration, and other solutions. Service providers are exploring technologies for more efficient, flexible, and cost-efficient network operations that will in turn make their businesses more agile and competitive.
Last year at Cisco Live in San Diego, Cisco introduced a broad vision and strategy ̶ The Cisco Open Network Environment ̶ an evolutionary approach that not only includes SDN but also encompasses an array of solutions, products, and technologies that are applicable to most, if not all, use cases that are much broader than what SDN alone could address. Since then, as part of our “Build, Buy, and Partner” strategy, we have announced newly developed technologies and products accompanied by strategic company acquisitions that add tools to enhance visibility, orchestration, programmability, and other capabilities to Cisco offerings.
At the end of January at Cisco Live in London 2013, we discussed a variety of solutions that we are working on with service providers to start their journey toward making their networks more programmable. From custom routing and traffic processing, to security applications and automation of fulfillment and assurance, here are just a few of the use cases explored and implemented by early adopters of our technologies that were discussed: Read More »

This blog is live from the floor of Cisco Live in London. The highlight for me this year in London has been the introduction, with our partners Ping Identity, of the Identity Cloud Connector, built on onePK, as part of the Cisco Cloud Connectors family of solutions. I’ll go into that in more detail below, but first some other highlights.
Yesterday we delivered a full day workshop on network automation, including EEM and introductions to onePK. Bruno Klauser, Joe Clarke, Jason Pfeifer, with me in a supporting role, helped 29 attendees through a series of exercises to help them get the most out of the extensive automation features on our platforms. The attendees must have liked it, as the score was 4.61/5. Well done guys!
The buzz here in the World of Solutions (WoS) is great. We have onePK demonstrations in the Data Centre and Borderless Network architecture zones, and we have been talking to customers and partners non-stop, all day. The Open Network Environment (ONE) strategy has really gripped people’s imagination, and it has been very exciting, and fun, to engage in some serious conversations about what ONE can do for our customers’ businesses.

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:

The constant need for more speed, mobility, and insatiable demands for access to information, continues to strain the capacity of service provider networks around the globe. In essence, whatever capacity made available will be consumed.
An open question on the minds of the operators -- how can they leverage SDN to not only keep up with these demands but maintaining a highly profitable network business? Such was the topic of conversation amongst operators and our CTO, David Ward, during a panel discussion at the recent Broadband World Forum (BBWF) in Amsterdam.
What lies in the balance for operators — a plethora of Read More »
