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 […]
Broadband WAN
Southernitman, a self-identified IT manager on Reddit, recently posted his dilemma on choosing between MPLS or an SD-WAN solution, commonly referred to as WAN Virtualization. Here’s how I thought he and anyone else considering MPLS should analyze the technology. THE QUESTION Southernitman said on the […]
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 […]
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 […]
The commonly used means of providing internet access to remote or small offices is via a wired (or fiber) connection. From ISDN through ADSL to T1 and DS3 lines, much money has been spent on provisioning and operating such lines. However, times are changing, and […]
Many IT shops are looking at ways to adapt their corporate infrastructure to a Software-Defined Wide Area Network (SD-WAN) that enables an open networking ecosystem across multi-vendor equipment. The October 2014 report from the ONUG (Open Networking User Group) SD-WAN Working Group, entitled Software-Defined WAN […]
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 […]
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, […]
