A few weeks ago, Cisco introduced our new vision for enterprise-wide network architecture based on the Cisco Open Network Environment (ONE) framework. This approach is not a radical departure from traditional networks, but a transformative architecture that brings unprecedented openness and programmability to enterprise-wide networks (not just data centers) to be ready for the Internet of Everything. It transforms networks making them more agile, high-performing and application-centric, while making the best use of existing network resources (brownfield deployments).
The need for this architecture is predicated upon the increasing number of applications, the complexity of deploying them, and the fast changing business environments that they need to support. These environments include multiple mobile devices users are bringing into the network as well as the sensors and other connected devices we expect will make up the 50 billion networked devices Cisco and GE have predicted for 2020. They also include new cloud-based application deployment models. This complexity is impacting the networks that need to serve these environments. Read More »

Among all the Megatrends that have significant implications from an infrastructure perspective (as discussed here), the one that customers in EMEAR currently expect the most from Cisco is Clouds. Both in terms of technical guidance as well as architectural innovations.
In the Cisco Cloud approach, intelligence in the network can help ensure delivery of cloud services, provide access and services to the right users, and offer the flexibility to connect with public, hybrid, and community clouds.
As shown in the illustration to the right, three main elements must be considered to build an efficient cloud. In addition, the network needs to provide dynamic access to these resources, and the Cloud applications and services must deliver anywhere, anytime access.
With the emergence of Cloud architectures, innovation is required within the network to allow IP to gain two critical features not natively provided by IP today: IP mobility and the Virtual Private Network (VPN). Read More »

Although I’m calling it the software strategy, it really targets the development of two specific standards: software image and configuration template. Choosing the correct software will be a critical factor in the success of a deployment. All the design and best practice efforts will amount to nothing if a critical defect is encountered in software. Software defects have created their fair share of network outages but what’s most frustrating is that many of these outages are caused by well-known defects that could have easily been avoided with a little research!
Software Risk Analysis
It has been my experience that often customers will deploy a hardware platform with the software that came installed from the factory. As you can imagine, this leads to a very diverse deployment of software. In this instance, diversity is not good as it creates a scenario where you cannot manage the risk and it is left to chance. Standardization of your software releases will put you in control of the risk and allow you to properly research software prior to deployment. Read More »

In my previous blog, I talked about building out a lab to help with IPv6 integration testing. It cannot be understated how important it is to test any new feature that is going to be deployed on the network. This statement is true independent of the feature involved. In this case, we are talking about IPv6, but we could just as easily be talking about virtualization or BYOD.
So now that we have the lab build up in progress, what’s next? Read More »

The UTC TELECOM conference wraped recently and the Connected Grid team has had a great time on-site! It’s been exciting for us to demo key components of our product portfolio and connect with many of our core audiences. Centered on the theme of “delivering your future,” the sold-out event served as a great platform for us to discuss Cisco’s efforts within the utility industry and the migration of the grid into a fully IP-enabled world.
