Internet Connections Can Be Used For More Than Best Effort Traffic

The topic of WAN transformation is certainly nothing new, but the shift to mobile and cloud computing is making the evolution of the WAN something businesses must make a priority. Prior to being an analyst I ran some fairly large WANs, and for as long as I can remember there has been talk of trying […]

It’s The Software, Stupid! But Also The Hardware And ASICs

The mania around software is at an all-time high. Everyone is a software vendor and it seems no one wants to be in the hardware business anymore. Software is the new, sexy item and people flock to software solutions like teens flock to Taylor Swift — hardware is so last century. However, I think it’s […]

Why CEOs Should Care About Software-Defined Networks

The momentum around Software-Defined Networks (SDNs) continues to be as strong as ever. It’s hard for me to have a discussion with anyone in technology without the topic of “software-defined” something coming up. However, recently I’ve had a few discussions with non-IT individuals about the value of SDNs and why they should care about them. […]

SD-WAN To The Rescue

Sofware-Defined WAN (SD-WAN) technologies are a hot topic right now in the networking world. Here we have a case of two extremes coming together. One extreme is the WAN, which has seen little fundamental development in roughly a decade. The other extreme is Software-Defined Networking (SDN), which has been a focal point for massive development […]

Net Neutrality: Don’t Bet Your Business Against It

Net Neutrality: A Force To Be Reckoned With OTT (Over-the-Top) content (notably video) on the public Internet continues to tie up yet more of the public Internet capacity. Infrastructure providers, however, are wary of investing heavily in new infrastructure capacity since with net neutrality they have little chance of monetizing these investments. On their side, […]

Who’s Who in Virtual Networking: Nick Buraglio

Who is he? Nick is a network engineer at the Energy Sciences Network (ESnet) of the Lawrence Berkeley National Lab (DoE). He’s part of the distributed team responsible for managing a heterogeneous, international, high-performance network consisting of production MPLS/VPLS, L2, L3, and disruptive technologies layers (OpenFlow, SDN and dark fiber) connecting all US Department of […]

Wake Up Your Redundant WAN Link

Many enterprises I speak with are looking to leverage low-cost, Internet lines for backup or even to offload traffic from more expensive MPLS connections. The Hybrid WAN, as this approach is called, is too complex to be built with conventional routing. Here are the three steps you can follow to build a Hybrid WAN in […]

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 […]
