Internet Load balancing is the act of spreading a large workload or capacity across multiple sources.
In computing, it is the spreading of work across multiple computing resources such as computers and central processing units.
In network load balancing, traffic is spread through multiple servers, so one server does not bear the full workload. This is especially helpful in websites today where it is commonplace to receive considerable amount of traffic to a site. All those requests must be distributed so they are spread over a collective of servers.
Among the types of load balancing there is also internet load balancing. This is the spreading of internet traffic over two or more connections and is the type of load balancing that we will further delve into.
As it relates to spreading internet traffic over various connections, internet load balancing or more specifically Dual WAN (wide area network) load balancing is where two or more internet connections, (typically broadband connections such as fibre or cable) are connected to a load balancing router’s WAN port. The WAN port is simply what connects to the external internet, hence those two internet connections are WAN connections. The internet traffic is managed in the most ideal and efficient way across the WAN connections.Your internet traffic is shared through these internet connections which you have connected to your desired WAN ports on your router.
So who exactly employs load balancing? Who is it useful for?
Well, fundamentally anyone can take advantage of this method. Businesses with a lot of internet users, or even for simple home use. It is important to note, it is not perfect, while there are numerous benefits to applying this method, inversely certain limitations exist. You are limited to the speed you choose for your connections. Two 4mbp/s (megabits per second) connections through your dual WAN load balancing router does not mean you now possess a combined 8mbp/s connection capacity for your internet. This is a common misconception about load balancing. A 6mbp/s video stream can be viewed because one holds two 3mbp/s connections, you are still limited to only viewing at best a 3mbp/s video stream.
Your business or home internet can still profit from load balancing. The advantages are bountiful in contrast to the limitations.
For starters, implementing more than one internet connection may seem daunting and high priced. The reality is, prices have changed a lot in recent years in relation to the internet. You may find you are hardly paying extra in addition to what you may already fork out for your services, if at all you end up paying anything additional. Therefore, it is a fairly cost effective and viable method for consideration. Moreover, it provides the ability for your internet to utilise internet failover. This means when one of your internet connection’s goes down, the other will take over. This alone grants more benefits in itself. You would now have reduced downtime in your home or business internet, which leads to an increase in productivity.
