Energetic debates of what SDN is and the expanding scope of what it can do for our customers continue to race along in a chaotic frenzy. In addition, the overall SDN market is somewhat fragmented in terms of both vendor positioning and marketing. Collectively, the conversation really comes down to improving business agility and the efficiencies gained in bringing new services to market. Essentially, the goal is to enable operators to make their networks and services go much faster.
While software defined networking (SDN) technologies continue to drive significant entropy in our industry, Network Function Virtualization (NFV) recently rose up and became a key focus of many discussions at Mobile World Congress in Barcelona last month. Read More »

I had the great privilege of participating on a panel at Mobile World Congress 2013 along with our customers, Deutsche Telekom and Vodafone, and my peers from Ericsson and Huawei. We discussed the evolution of the Network Architecture for mobile service providers.
From the infrastructure to the user, everyone agrees that the future will both bring and be driven by significant changes to the Network. In particular, by bringing together access, network and cloud we will create new business opportunities and enhanced user experiences.
Let’s start with some technology trends and market transitions: Read More »

Human beings are nomadic, social creatures by nature. Throughout the course of human history, we have innovated new communication technologies to help us stay in touch with our social networks while we roamed the globe. In today’s digital connected world, we have become “addicted” to mobility because of all the ways it enriches our life experiences. As proof of this fact, just watch how quickly passengers turn on their smartphones upon landing when you take your next flight.
Cisco is at the very center of the mobility technology revolution that is connecting the previously unconnected to benefit how we work, play, live, and learn. Our technologies and solutions have helped service providers build out their network infrastructure to give reliable mobile access to people and things in the places that matter most. Not far off on the horizon, mobile connections will be seamless and ubiquitous and the network infrastructure will be heterogeneous and transparent to the user.
Today, Cisco is Read More »

In my previous post, I talked about how networking was a large part of the discussion at the oVirt Kickoff Workshop. Increasingly, the network is elevating itself to be a first-class citizen in large open source infrastructure and cloud projects, including open source projects like OpenStack and now oVirt. In OpenStack, the Quantum project is the result of these discussions. Newborn community projects such as oVirt are starting to look at elevating the network to provide advanced functionality as well. It was no surprise a large portion of the last day of the workshop was spent on networking, with an early focus on Quantum.
The last day of the workshop started out the morning with an overview of SDNs and Quantum by Lew Tucker, CTO of Cloud at Cisco. Lew drew a nice overview of cloud networking on the white board, presenting an app-centric view of cloud and virtual networking. In the cloud network model, apps care only about connectivity to the network, not how that connectivity happens, thus the focus on apps as the center of this world.

After Lew was done, Dan Wendlandt, project lead for Quantum, presented his Quantum slides. This was helpful to level-set everyone at oVirt with regards to Quantum and OpenStack. One of the main pain points with looking at how Quantum can be shared from OpenStack into oVirt has been the difference in the networking models. OpenStack presents a very cloud-centric view of networking, whereas oVirt wants a more datacenter-centric model. Quantum was designed to generally be agnostic to the deployment model, so using it in oVirt should be a matter of fitting it into the architecture.

After Dan was done giving a broad Quantum overview, Ram Durairaj from the Cisco OpenStack team presented on Quantum L3 Services. Currently, Quantum is designed to address the L2 abstraction of the network. Quantum L3 Services are meant to expose L3 concepts such as subnets and gateways into Quantum and the plugins. It would also allow for routing between tenant domains.

Now that the oVirt Kickoff Workshop is over, watching how the networking story with oVirt evolves will be interesting. The success of oVirt will be the result of the community around it, and the ecosystem for third party vendors it creates. With regards to networking in oVirt, the interactions between the Quantum community and the oVirt community have only just begun, and the future looks like a very collaborative affair between the two projects.

The formation of a new community in the Open Source world is an exciting time. We at Cisco were lucky enough to participate in the formation of one such community while hosting the oVirt Kickoff Workshop at our San Jose headquarters. In making the decision to Open Source their RHEV-M product, Red Hat also decided to create a community, and ultimately an ecosystem around oVirt. The workshop filled up early after being announced, and the presentations and discussions have given the new community a look at the assets Red Hat is placing under the oVirt umbrella.
One area generating a significant amount of discussion was the network. The discussion revolved around elevating the network as an equal to other components of oVirt. If this sounds familiar, it is because the exact same discussion was recently undertaken in the OpenStack project, the result of which is the Quantum project. Quantum is an attempt to create a standalone network service, capable of provisioning virtual and physical networks. In OpenStack, it works with Nova to create networks and bring up interfaces, attaching them to those networks. Given Quantum was created to be standalone, looking into how it could integrate with oVirt seems logical. Quantum has the potential to become a clear way to consolidate the handling of network topologies and overlays, both hardware and software, for OpenStack and oVirt. With it’s plug-in architecture, vendors can provide value with their hardware or software plug-ins, writing a single plug-in to enable their network technologies to work on both OpenStack and oVirt.
With one day left of the Workshop, the workshop will shift to BoF sessions, as well as roadmap and release scheduling. Cisco is excited to not only be a part of this community, but also to be a strategic partner with a board seat. Going forward, we hope the excitement level demonstrated at the workshop will carry over as the community drives to the initial release of oVirt.
