In the previous post, we have learned the basics about SD-WAN. Today, we are going to learn more about why many multi-location businesses choose SD-WAN and how secure it is comparing to traditional WAN connectivity. Let’s get to it:


A short answer would be: SD-WAN can offer you a seamless, secure connectivity across your multiple communications platforms efficiently with lower costs.

Traditionally, when you have multiple branch offices connected to your headquarter, the traffic from each branch is pulled across the WAN links to your main site. This process is very inefficient and expensive. Now with SD-WAN, you have a direct Internet connectivity that gives you consistent performance to your applications at lower costs.

One of the biggest advantages of SD-WAN is that it can act like a sensor that provides intelligent path control to make smart real-time decisions to prioritize your tasks/ traffic and assign just the right amount of space for each task. (no waste at all!)

Better yet, This capability can be set at a single control center and then push out to all SD-WAN devices at the same time. This makes your network extremely efficient and it will highly improve your quality of service (QoS)! Learn more about QoS here.


How secure is SD-WAN?

Most SD-WAN solutions will be able to complement and supplement your existing security environment and protocols. This makes SD-WAN more reliable and secure than WAN connectivity.

Traditional WAN solution handles security through multiple appliances at each of your branch offices which makes it more time-consuming and difficult to manage. However, with SD-WAN solution, you will have the ability to define, monitor, and enforce network policies all from a single managed center.

The WAN connectivity is already in the past. If you have remote offices or branches but you are not using SD-WAN yet, you are really falling behind!

Learn More about SD-WAN

If you are one of the billion VoIP users in the world, you must have heard about SD WAN by now. It is surely a big buzzword lately as we are more aware of the importance of VoIP security and call quality. So let’s find out what’s all the buzz about!

What is SD WAN?

SD-WAN stands for “Software Defined Wide Area Network”. It is a new technology that centrally connects and manages multiple locations using a variety of internet connections.

How SD WAN Works

When SD-WAN is utilized on the Cloud-based controller, it doesn’t matter how many locations you have or how far they are from each other, as long as the devices connect to your SD-WAN provider, you’ll have a singular infrastructure to manage your entire network easily. Now you can remotely program edge devices and reduce provisioning time and costs!

Unlike a traditional system, SD-WAN senses the quality of all your connections and routes the traffic to the best path to optimize your call quality and make sure your system is up and running seamlessly at all times.

I’ll admit it. The term “Software Defined” or “SD” is as big a buzz phrase as “The Cloud.” I’m not a huge fan of buzz nomenclature, but sometimes it is the best way to describe a concept in a familiar way, especially when discussing technology. If I were playing devil’s advocate, I’d ask: Isn’t everything software defined? Yes, mostly it is, but when you say SD, or SDN (software defined networking), you imply a new iteration of conventional thinking. A new way of doing things, a more flexible, better way.
No longer are we bound to the holy gospel of Cisco, or dedicated internet circuits. We can do things with more intelligent, dynamic, and overall thoughtful methods. Gone will be the days of individually configuring routers and switches because they will all be centrally managed and monitored. Yes, Cisco already participates in SDN, but I’d argue that it’s not always affordable for the average SMB.

Software Defined WAN (SD-WAN) is a concept of centrally connecting and managing multiple sites or branches using a variety of internet connections. For example: DOCSIS (cable modem), 3G/4G, or line of sight wireless. The internet is to reduce dependency on technologies like multi-protocol label switching, which traditionally required leased lines from the same provider. If you’ve had to purchase one, you know that leased/dedicated lines are expensive. You can use SD-WAN to augment an existing MPLS connection or discard it all together which will generate significant savings for your business.

SD-WAN (also referred to as vMPLS) is a feature on services like SimpleWan and can be utilized on their cloud based controller. When you purchase a firewall from them and a subscription to their service, you achieve a single sight picture of your entire network regardless of how many branches you have. Also, I’d like to re-emphasize that SimpleWan, and subsequently SD-WAN is carrier agnostic. So, it does not matter if you have multiple locations from one end of town to the other, or from New York, to Beijing. As long as the devices can connect to SimpleWan, you have a singular infrastructure with potentially very diverse internet connection methods.

security-imageYou might be thinking: Why not just use VPNs? Well, you are, but with SD-WAN you’re using a variety of technologies that perform the configuration for you, and establish redundant meshed paths that can decide which direction to send traffic based on bandwidth. Like I said before, SD is a new iteration of the conventional.

What does any of this have to do with VoIP? Well, if you’ve read ANYTHING regarding SIP and NAT, you’ve found out they don’t traditionally get along. Leveraging SD-WAN allows you to bypass any NAT traversal increasing your success with two-way audio. A SIP phone is much happier when it can talk to another local IP and the other end. I’d also be remiss in not mentioning that Quality of Service (QoS) in an integral part of SD-WAN which can prioritize voice and video applications.

Give SD-WAN (from SimpleWan) a chance if you’re considering cutting the cord from your expensive MPLS circuits. As always, thanks for reading and happy VoIPing!
