SD-WAN Benefits: More than Eliminating MPLS
SD-WAN Benefits: More than Eliminating MPLS
/ Aug 3, 2017 0 COMMENTS

Most of the discussion to date on the benefit of SD-WANs has focused on how an SD-WAN enables a network organization to reduce or eliminate its spend on expensive MPLS circuits. That is clearly an important benefit. However, as many early adopters of SD-WANs can attest to, SD-WANs have other important benefits. I am going…

The 2016 State of the WAN report contained the results of a survey in which the respondents were asked to indicate the factors that were having the biggest impact on their WAN. Given that unlike the LAN, the WAN exhibits performance limiting characteristics such as high levels of packet loss and latency, it isn’t surprising…

A recent article identified what Gartner considers to be the top 10 strategic technology trends for 2017, one of which is machine learning. Per that article, machine learning has reached a tipping point and will increasingly augment and extend virtually every technology-enabled service and application. While I agree with that assessment, I don’t think that…

In my last blog entry I pointed out that 2017 will be an important year in terms of the adoption of SD-WANs. In that post I discussed some of the technical characteristics of SD-WAN solutions that network organizations should pay close attention to, since these are the characteristics that will determine whether or not these…

In 2016 SD-WANs were the hottest topic in networking. That raises an obvious question that I will use the next two blogs to try to answer. That question is: What changes can we expect to see relative to SD-WAN adoption in 2017? The multi-year SD-WAN adoption model It is somewhat common in our industry to…

Over the last 18 months one of the hottest topics in IT has been software defined WANs (SD-WANs). One of the advantages of SD-WANs is that they enable companies to leverage relatively inexpensive Internet bandwidth. There is no doubt that having additional bandwidth eliminates some performance problems. However, network organizations that are analyzing SD-WAN solutions…

We have been discussing Software-Defined WANs (SD-WANs) for about eighteen months. As is the case with any new approach to networking, the initial focus of that discussion was on basic topics such as what is meant by the phrase SD-WAN.  As we get closer to the time when a lot of companies will start to…

Everybody in IT is aware of the hype cycle that surrounds the introduction of new technologies and architectures such as a Software-Defined WAN (SD-WAN). There are two key factors that drive that hype cycle. One of the factors, having unrealistic expectations of the benefits of a SD-WAN, was the subject of my last blog. In…

There is a tendency in our industry to associate emerging technologies such as Software Defined WANs (SD-WANs) with a very broad, and often unrealistic set of benefits. This tendency tends to add to the hype that surrounds new technologies and it makes it difficult for network organizations to accurately evaluate the viability of adopting these…
