The Role of SD-WAN in the Change of Traditional WAN

BY futurefirewall

SD-WAN's relationship to regular WAN.For businesses that are interested in a wide-area network (WAN) to improve their operations, especially those operations with multiple locations, a WAN might seem like a good idea. At least it does until its close cousin, the software-defined wide-area network (SD-WAN), steps in. The SD-WAN does improve on the traditional WAN pretty substantially, but is there still life left in the standard WAN in the face of its software-defined cousin?

The SD-WAN’s Role in the Future of WAN

There’s no non-subjective way to talk about the future of anything, but some trends seem to have emerged.

The regular WAN is dead? To hear some talk about it, the standard WAN really doesn’t make that much sense anymore against the SD-WAN. That’s mainly because the WAN requires so much more legwork than the SD-WAN does. A WAN requires leased lines, as well as privately-owned routers. The SD-WAN, being software-based, doesn’t really need that so much as it does a standard internet connection.

Improvements on the base. While the traditional WAN may no longer be so useful in the face of the SD-WAN, the SD-WAN would not exist without the WAN’s earlier efforts. With SD-WAN, users get access to higher capacity, better reliability, and a better overall experience as well. And often, it’s all for significantly less expense and effort than a WAN would have required.

Issues to be considered. While an SD-WAN is actually a healthy improvement over the WAN in several ways, there are still points to watch. For instance, many SD-WAN providers will push lower costs but not factor into account the quality of the internet connection involved. This can reduce the overall quality of the experience, so it’s a point to consider.

Global companies have the toughest time. If you’re a company operating in several countries, or even on multiple continents, SD-WAN can have some issues here too. The laws of physics remain constant, and so too does lag caused by issues in the speed of light. There is a maximum limit to signal transfer speeds, and the farther apart the locations, the more noticeable the lag is.
