With a rapidly increasing number of people, devices, machines and sensors coming online across the Internet of Everything (IoE), global service providers will require new capabilities to lead in the delivery of value-added, cloud-based services and applications. Service providers are recognizing the importance of using intelligent, virtualized networks that efficiently deliver new experiences and expand revenue opportunities. While there are many residential, business and mobile solutions that service providers can offer, network virtualization is also crucial for deployment in developing regions.
The IoE aims to bring the world together through technology and empower those who were once isolated, by transforming the ways they communicate. Access to mobile technology varies and may not be as prevalent in developing regions of the world. However, tablets and mobile phones are beginning to transform how these developing regions obtain and relay information. In fact, mobile phone subscriptions have climbed to nearly 5 billion in the Read More »

I know that I take a different approach to learning new things than most people. At least, I know my approach is different than the way people present them. The good news is that when I get something, I really get it. However, when looking at the juggernaut that is “Software-Defined X,” or even “programmability,” I know that I’m still a long, long way away from feeling like I have a handle on it.
When I wrote the previous blog post on some of the key “Open” terms were in programmability, I was overjoyed to find out that there were a few people who also had difficulty getting a grip on this too.
In other words, I’m not alone!
There is still a bewildering amount of information that I still need to learn, however, and it seems to me that if I resonated with a few people about these high-level topics, there are probably a few more who are curious about what lies beneath as well. Fortunately I work for a company (and with a lot of people) who have been willing to help me. Read More »

Part 2 – Virtualized Services in an EPN World?
In part one of this series Gina covered the basic definition of an Evolved Programmable Network or EPN and its linkage to the Cisco Evolved Services Platform (ESP). Figure 1 offers a quick visual recap.
Figure 1: Cisco’s Open Network Strategy
And here’s a link to part one of this blog series if you need to play catch up.
In this segment we Read More »

Software Defined Networking is at the center of many discussions and debates regarding networking, and right fully so. It means many different things to many different people, and there is a lot of confusion and discrepancy in the term. You can ask 10 different people what SDN means, and you will get 10 different answers. If you ask me, SDN is today what cloud was five years ago. I won’t attempt to define what exactly SDN means, but what I will say is that like cloud, the value of SDN will clarify itself over time with powerful use cases and meaningful applications. Case in point, at the Spring 2014 Open Networking User Group (ONUG) meeting in New York City, the ONUG board of directors proposed nine different use cases that were most likely to be in an RFI/RFQ in the next 12 months. From these use cases, the IT business leader community at ONUG chose Software Defined WAN as the most critical use case in open networking today.
While the idea of SDN in general is exciting and powerful, most companies are in the planning stages of their SDN and automation vision. Most believe it will take at least two to three years to architect and realize the benefits of automation across the enterprise. What’s driving SDN is the promise of the following benefits:
- Management: Manual -> Automated Networks
- Configuration: Box Centric -> Network Wide
- Speed/Agility: Weeks/months -> Minutes
- Interoperable: Closed system -> Open System
Currently, there are very few, if any, companies who have completed their SDN strategy. Partially because it’s quite complex with many permutations, and partially because it’s so important to get it right. While planning for SDN and automation in the enterprise, there are two key things to consider:
- SDN applications must add value to the existing network today
- SDN applications must be able to integrate into the customer’s vision for SDN and automation.
There will be a transition between beginning and end state, but any SDN tool being considered must show value on the network as it is currently deployed and allow for integration with future architectures and platforms. If these considerations can be met, there is a clear reason to begin deployment today. Companies desire a mature solution in global production that enables value through SD WAN, meeting all of the benefits above, not just the promise of those benefits. Glue Networks can provide these benefits. Read More »

As business leaders navigate an increasingly complex world of connections, they need IT to provide a programmable infrastructure that can dynamically respond to their needs. This four-part blog series explores how responsive infrastructure helps IT leaders succeed. The first post in this series, by Colin Kincaid, discusses how Fast IT, a new model of IT, offers a broader focus of next-generation infrastructure. The second post in this series by Jim Grubb highlighted what IT leaders can do now to adopt a roadmap to Fast IT. The third post in this series by Doug Webster discusses how service providers specifically stand to benefit from Fast IT. Today’s post, the final in this four-part series, will explore how a Fast IT model can mitigate common infrastructure challenges.
Many organizations realize that they need to change the way they are networking today and they are looking to SDN as the answer. However, the answer is broader than SDN.
To succeed in a new world of networking, organizations need a Fast IT model. In other words, an infrastructure that embraces technology transitions using programmability, automation, orchestration, virtualization, and security throughout.
As executives look to future-proof their business, many are facing innovation challenges in today’s infrastructure landscape. IT organizations are increasingly expected to drive revenue growth, reduce operational costs, mitigate security risk, and increase innovation – and do it all faster than ever before. Today, it is absolutely critical for IT to partner with the business and continue to be relevant to the organization’s growth.
So, what distinctive differentiation points of a next-generation infrastructure can mitigate these challenges? How can Fast IT help IT organizations deliver greater business value?
Challenge #1: Be More Agile
It’s becoming clear IT needs the ability to respond quickly. There is a growing proliferation of IT as a Service (ITaaS) applications that supplant traditional service models. And in today’s landscape, business agility requires application agility, so IT teams need to provision applications much faster. IT leaders are increasingly measured by their speed to deploy applications because this will determine how successful they are in new markets and new business models.
