Addressing Business Outcomes Through The Intercloud

At this year’s Cisco C-scape EMEAR analyst event, the vendor downplayed its hardware product launches, focusing instead on its rapidly evolving business credentials. Cisco, with its oft-repeated message of massive Internet traffic growth, talked this time about business outcomes, and delivering all the elements – hardware, software, and professional services — to make that happen.

Should Enterprise Take a Big Bang Approach To NFV?

As the interest in SDN continues to increase, we are also seeing growing interest in a related network architecture: Network Functions Virtualization (NFV). Organizations that are evaluating the viability of NFV have to make a key decision early on: Should they go forward with a piecemeal approach or should they go for a big bang […]

The Software-Defined WAN and WAN Optimization: Networking’s Dynamic Duo

Today’s WANs have become remarkably complex. What used to be relatively straightforward point-to-point links have multiplied, meshed, and hybridized, as well as gaining layers of management and optimization to overcome the inherent weaknesses of telco connections and wring more capacity from them. At the same time, more and more users and services are moving off […]

Operational Challenges Continue To Plague Legacy WANs

Much of the value proposition for the shift to a hybrid WAN is to improve application performance, which is often poor over WAN. However, the challenges with a legacy WAN go beyond application performance. Operational issues are as big or a […]

Security-Focused Shift to SD-WAN Threatens DC Supremacy

Enterprise adoption of the Software-Defined Wide Area Network (SD-WAN) architecture opens up significant improvements from an operations, cost, and flexibility perspective. But it’s a big forklift infrastructure shift, where company size, and thus network complexity, are crucial factors in any decision to embark on the SD-WAN journey. What Will Drive SD-WAN Adoption? The work done […]

Where Do We Stand With SDN?

I wrote my first analyst report on SDN back in 2012. Since then there have been more analyst reports, white papers, and blogs written on SDN than I or anybody else could ever count. The sheer volume of documents on SDN can lead networking professionals to become SDN-weary. However, since it is often the case […]


The commonly used means of providing internet access to remote or small offices is via a wired (or fiber) connection. From ISDN through ADSL to T1 and DS3 lines, much money has been spent on provisioning and operating such lines. However, times are changing, and rather than regarding an organization as a grouping of central, […]

4G LTE Plays Well In The SD-WAN Infrastructure

Many IT shops are looking at ways to adapt their corporate infrastructure to a Software-Defined Wide Area Network (SD-WAN) that enables an open networking ecosystem across multi-vendor equipment. The October 2014 report from the ONUG (Open Networking User Group) SD-WAN Working Group, entitled Software-Defined WAN Use Case provides input for enterprise planning efforts. High quality […]

All I Want For Christmas Is Some Dumb IP

Well, it’s that time of the year – the time when we’re thinking about what we want for Christmas, and what we will get our friends and family. If you’re looking for the perfect gift for that network manager in your life, try getting some dumb IP, otherwise known as plain old Internet services. Why […]
