Cord-Cutting Comes to the Enterprise WAN

The advent of low cost, high-speed Internet connections to the home paired with online streaming services such as Netflix has started a trend known to many as cord-cutting. Cord-cutters — those who choose to eliminate their subscription to expensive cable TV services — have quickly realized that they can reduce costs and still maintain high […]

Hybrid WAN — It’s Time To Do The Math

With more applications hosted by SaaS providers and businesses constantly looking at ways to drive down costs, without sacrificing performance, companies are looking at ways to augment or replace their costly MPLS WAN infrastructure with the Internet. MPLS networks have long served the needs of the enterprise, however more businesses are realizing that they are […]

SD-WAN Economics: What Will You Do With a 5% Increase in Budget?

Tony made an interesting point about the inclusion of SD-WAN within Gartner’s Magic Quadrant for WAN optimization controllers.

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 […]

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 […]
