It occurred to me today, that in all the years I have been posting about common ways to speed up your Internet, I have never really written a plain and simple consumer explanation dedicated to how a bandwidth controller can speed up your Internet. After all, it seems intuitive, that a bandwidth controller is something an ISP would use to slow down your Internet; but there can be a beneficial side to a bandwidth controller, even at the home-consumer level.
Quite a bit of slow Internet service problems are due to contention on your link to the Internet. Even if you are the only user on the Internet, a simple update to your virus software running in the background can dominate your Internet link. A large download often will cause everything else you try (email, browsing) to come to a crawl.
What causes slowness on a shared link?
Everything you do on your Internet creates a connection from inside your network to the Internet, and all these connections compete for the limited amount of bandwidth which your ISP provides.
Your router (cable modem) connection to the Internet provides first-come, first-serve service to all the applications trying to access the Internet. To make matters worse, the heavier users (the ones with the larger persistent downloads), tend to get more than their fair share of router cycles. Large downloads are like the school yard bully – they tend to butt in line, and not play fair.
So how can a bandwidth controller make my Internet faster?
A smart bandwidth controller will analyze all your Internet connections on the fly. It will then selectively take away some bandwidth from the bullies. Once the bullies are removed, other applications will get much needed cycles out to the Internet, thus speeding them up.
What application benefits most when a bandwidth controller is deployed on a network?
The most noticeable beneficiary will be your VoIP service. VoIP calls typically don’t use that much bandwidth, but they are incredibly sensitive to a congested link. Even small quarter-second gaps in a VoIP call can make a conversation unintelligible.
Can a bandwidth controller make my YouTube videos play without interruption?
In some cases yes, but generally no. A YouTube video will require anywhere from 500kbs to 1000kbs of your link, and is often the bully on the link; however in some instances there are bigger bullies crushing YouTube performance, and a bandwidth controller can help in those instances.
Can a home user or small business with a slow connection take advantage of a bandwidth controller?
Yes, but the choice is a time-cost-benefit decision. For about $1,600 there are some products out there that come with support that can solve this issue for you, but that price is hard to justify for the home user – even a business user sometimes.
Note: I am trying to keep this article objective and hence am not recommending anything in particular.
On a home-user network it might be easier just to police it yourself, shutting off background applications, and unplugging the kids’ computers when you really need to get something done. A bandwidth controller must sit between your modem/router and all the users on your network.
