Load Balancing Routers

What is a load balancing router?
A load balancing router is a router which can use more than one Internet connection simultaneously to provide internet access to devices connected to it.

One of the benefits of load balancing is that it allows a network to utilise more bandwidth than a single connection can provide but also it allows a site to gain resilience by relying on more than one network connection and removing a potential single point of failure.

Another benefit of load balancing could be to direct traffic to a different network connection based on the destination that needs to be reached. An example could be one WAN which is connected to a private network and another WAN which connects to the public internet.

The best load balancing routers will give flexibility on the load balancing rules which they can be configured with and will support multiple different connection types to gain diversity so that it’s unlikely that a network outage affects multiple connections simultaneously. For example if both connections use the same street side cabinet and a lorry knocks it out and takes both offline simultaneously.

A common approach could be to use one connection on FTTC & one on Mobile broadband (4G / LTE), or one FTTC and one FTTP so that the internet load balancing router is using different types of connection that are unlikely to be simultaneous affected by the same network outage.
