What is WAN Bonding?

Let’s understand WAN Bonding.

You may have heard of Internet bonding. It is really quite a simple concept. Two or more Internet connections can actually be taken and combined into a more powerful singular connection. Why would anyone do this? Well, simply put, one singular connection is simply not enough these days, especially if something were to happen to that connection. 

A lot of businesses these days implement Internet failover techniques even, which itself is not to be confused with Internet bonding. Internet failover simply switches your primary connection to a secondary one when the primary fails, ensuring you are always online. However, it is common for companies to skimp on the secondary connection to save money effectively making the solution not up to par in the end.

Load balancing, another technique employed to enhance the Internet is confused with Internet Bonding as well. Load balancing balances the traffic of the internet flow efficiently but differs to Internet Bonding. Internet Bonding does this but more efficiently and with the added benefit of a more powerful connection enabling a business to conduct its operations with the utmost of ease. It is a solution that far outdoes common techniques as aforementioned utilised commonly with the pursuit of enhancing an Internet setup.

Internet Bonding however, can be done efficiently through WAN bonding, specifically even through SD WAN. For those unfamiliar with SD WAN, SD WAN is software defined networking in a wider area network, which refers to a network spread over a large area connecting technologies. SD WAN is an implementation of software defined networking which is a structure used to make networks more flexible. 

Software defined networking or SDN for short, enables service providers and relevant companies utilising the structure to respond fairly quickly and efficiently to changing business demands and requirements. It increases the agility of networks, where traditional networks are more rigid and complex to operate, effectively attacking this problem point. An example of SD WAN is seen below.

Bonded WAN serves as an excellent solution to common problems suffered by business today. Deplorable connections that drag down operations seem to be corrected. But how is the connection powerful, how does it work? It’s quite as simple as adding two connections together really. Say you have a 3mb/s connection and one that is 7 mb/s, combine them and now you have 10mb/s. Through an extra port, you are able to bond two lines belonging to different internet services together i.e, NBN connection with another NBN connection or even NBN with a fibre connection, usually requiring extra equipment and installation. An instance of this is seen below

Newer SD WAN appliances can take multiple Internet connections and combine them together to create a more powerful connection that also has only one IP address. It gives businesses this option despite the internet options available in their area. Case in point, if a business or someone were living in a rural area they are able to combine multiple internet connections that are available to them to create something more powerful and suitable to their needs. Meaning, they simply don’t have to suffer with a very slow connection in a rural area with no hope of running their organisation efficiently.

Improving the resilience of your Internet connection, and enhancing the efficiency are among the many benefits of utilising WAN bonding by combining different internet connections through your WAN router, you are guaranteed a faster and more optimal speed set to enhance business functions. While it may be slightly more costly than a singular regular internet connection, the cost is greatly outweighed by the benefits provided. Internet bonding is most definitely a method best suited to be utilised for you or your organisation’s needs.
