Ripley’s Next Exhibit: The Internet Wide Area Network

If you’ve ever been to a Ripley’s Believe it or Not Museum, you’ll know it’s filled with things that are true, but hard to believe. For example, the museum has “ginormous” bugs that you can keep as pets, use to fight one another, or even eat! Hard to believe, but true. They also have microscopic […]

How Should You Be Thinking About Your WAN?

For a twenty year period that began in the mid-1980s the enterprise WAN went through a series of transitions, starting with Time Division Multiplexing (TDM) based on T1 access and then moving on to Frame Relay, ATM, and finally to MPLS. Unfortunately, over the last decade there hasn’t been a new transmission service introduced into […]

Internet Connections Can Be Used For More Than Best Effort Traffic

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 […]

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 […]

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 […]
