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 […]

Riverbed Admits Scaling Limitations

Riverbed and Silver Peak don’t usually agree when it comes to matters of WAN optimization scalability and for good reason. We’ve offered it; Riverbed hasn’t. But now in a recent blog, Riverbed has decided to tell us why its products don’t scale. Apparently, it’s because they’re like lattes. Let me explain. There’s been this misconception […]

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, […]

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 […]

Look Into the Crystal Ball for 2015 Networking Predictions

If you could peer into a crystal ball and see the end of 2015, what do you think you’d see? In the networking industry, 2015 is poised for more disruption than ever before. Whether it’s the growing interest in SDN, or the rapid emergence of SD-WAN, or even the growing frustration around the high cost […]

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

This site, like many others, has focused on the need to evolve the WAN. 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 […]

Understanding Service Chaining

One of the emerging topics of conversation related to Software-Defined Networking (SDN) has been something called “service chaining”. The topic has gotten a fair bit of media focus of late, resulting in an increase in the amount of inquiry on this topic. From the questions I’ve been getting, though, its become obvious to me that […]

Smaller, Quieter WAN Optimization for the Branch

A major challenge for distributed enterprises is providing branch office users with consistent application performance and reliability. But in many of these remote office locations, often in the retail space, some hardware just won’t fit in the smaller telco racks in their stores. And in environments where a networking closet doesn’t exist, fan noise can be a […]

Is NFV Just for Service Providers?

A lot of people that I talk to regard NFV as something of interest only to service providers. I think that perception comes in large part from the service provider orientation of some of the high-visibility organizations that have formed to drive the evolution of NFV. This includes an industry specification group (ISG) that the […]
