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 […]

Take Back the Control Plane

Much has been said about how Software Defined Wide Area Networks (SD-WANs) let IT better control the flow of traffic over distance, improve security, and lower costs. Over the past months, we’ve had a few conversations with IT managers that point to a perhaps less-discussed, but even greater benefit to this new technology. A few […]

The Top 5 Leaps of Faith When Building a Hybrid WAN

The hybrid WAN is an idea that’s been around for decades now. Prior to being an analyst, I worked in corporate IT and I was building Internet VPN links to connect home office workers, small branch offices, or back up connections. Back in the “old days”, a hybrid WAN was definitely the exception and far […]

Dear MPLS, We Need to Break Up

Dear MPLS, I’ve considered writing this letter for quite some time.  Fifteen years is a long time together, especially in the technology world. Many would say that this is long overdue. We’ve had our ups and downs as many relationships do, but alas, I’ve met someone else. When we first met in the 90’s you […]

Data Acceleration “Worst” Practices

I am constantly getting emails with “Best Practice” advice — for everything from traveling to IT. Well, it got me thinking: why doesn’t anyone provide “Worst Practice” advice? Can’t we all learn from other people’s mistakes? So here goes, this is my top 5 list of misconceptions and things to avoid in the data acceleration […]

It’s All About The RPO

I read with great interest a recent article by InfoWorld contributing editor Matt Prigge titled, “When WAN optimization really boosts network performance.” In general, I agree with the bulk of Matt’s comments — storage vendors are getting better at replication over long distance, some WAN optimization products don’t benefit from every type of replication — […]

The Lack of Innovation in the WAN

There are a number of differences between local- and wide-area networking.  One obvious difference is speed: many IT organizations are in the process of upgrading their data center LAN links from 1 Gbps to 10 Gbps, and they’re aware that 40 Gbps and 100 Gbps technology is under development.  In contrast, due to the prohibitive […]

Make Sure You Get the Right Fit

Have you ever gone into your garage to build or repair something, but were unable to find the tools to do the job. I’ve experienced this more often than I care to remember. But, when I’m able to quickly find the tools I need, it’s not only very satisfying, it makes the project easier to […]

Danger! Overload!

“I have a theory about the human mind. A brain is a lot like a computer. It will only take so many facts, and then it will go on overload and blow up.” – Erma Bombeck. Actually, the same thing holds true for the communication pipelines that drive today’s electronic commerce and business-to-business communications. Virtually […]

Is data center consolidation causing bloating and congestion?

If you answered “yes,” well, I’ve got the remedy. If your enterprise is feeling the ill effects of poor WAN performance, you may assume it’s a bandwidth problem. If you invested in more bandwidth and a bigger pipe to ease the pain, and the problem persisted, the problem may be due to packet loss, latency […]
