The Importance of Setting Network Baselines
/ Oct 27, 2016 0 COMMENTS

The networking industry is in the midst of a transition to the digital era. The network plays a critical role in the success of digital businesses as many of the digital building blocks, such as IoT and the cloud, are network-centric. This is one of the reasons why there is currently so much focus on…

Is Your Network Paying the Price for Internet Backhaul?
/ Dec 18, 2015 0 COMMENTS

In the traditional approach to branch office networking, organizations backhauled their Internet traffic to one or more of their data centers. The advantage of backhauling is that it gives network organizations the ability to secure this traffic relatively easily. The disadvantages of this approach are that it adds delay and cost. These disadvantages are clearly…

Is Hybrid WAN an Unnecessary Step to a Broadband WAN?
/ Dec 2, 2015 0 COMMENTS

A few weeks ago I presented on the state of Software-Defined Networks (SDN) at this years Open Networking User Group (ONUG) conference. During the section on SD-WAN I made a comment that I thought that hybrid WAN was an unnecessary step on the journey towards a broadband WAN. It appears I touched a nerve on…

To Maximize The Value Of SD-WAN, Look Past Hardware Savings
/ Oct 6, 2015 0 COMMENTS

I moderated a workshop on the topic of software defined WANs (SD-WAN) last month and I’m continually baffled that the focus of software-defined networking remains on the hardware for so many individuals. This is clearly a hangover from the early days of SDN when many of the start ups were hammering home the point that…

Where Do We Stand With The WAN?
/ Jul 30, 2015 0 COMMENTS

A lot has been written over the last year about how SDN will fundamentally change how enterprise WANs are architected. While I generally agree with that statement, I think it is important to not get too far ahead of ourselves. Before we implement any new networking technology or architecture we always have to answer a…

Metro Ethernet Can Be Part Of A Broadband WAN
/ Jul 14, 2015 0 COMMENTS

The concept of the broadband WAN is becoming a reality to more and more organizations every day. However, when I talk to network managers and IT leaders about the broadband WAN, cable and DSL tend to dominate the conversation. One broadband technology that never seems to get its due is Metro Ethernet. Metro Ethernet isn’t…

It’s Time For Network Operators to Embrace Internet WANs
/ Jun 25, 2015 1 COMMENTS

Disrupt or be disrupted. That was one of the key messages that Cisco’s outgoing CEO, John Chambers, gave in his keynote at the company’s user event, Cisco Live, earlier this month. The message is short and clear: the business climate is changing and you can either change with it or become irrelevant. One area that…

New EdgeConnect is a Breakthrough in Building SD-WANs with Broadband
/ Jun 15, 2015 0 COMMENTS

Despite the mounting frustration with MPLS, many customers still do not believe the Internet can provide the security and performance needed for today’s business-critical traffic. And while current conversations around leveraging the Internet for the enterprise WAN have focused primarily on the ability to use multiple network connections, and in some cases, zero-touch provisioning, we…

How Can You Go From WAN Theory to SD-WAN Reality?
/ Jun 11, 2015 0 COMMENTS

In the last few months a lot of articles have been written about the WAN in general, and about Software-Defined WANs (SD-WANs) in particular. These articles typically point out the well-known limitations of the current approach to wide area networking and discuss how to apply a variety of techniques, both old and new, to the…
