ADSL Speed and Performance Part 3 : Traffic and Shaping

 

Everything you need to understand about traffic shaping and optimization and how usage thresholds affect you.

 

That's a pretty self-explanatory picture, but let's run through it from the top:

 

First off we make sure our business customers are well taken care off. This split between business and consumer traffic does not mean our consumer customers are getting the short straw, but in the event of any serious network outages this split allows us correctly manage the network redundancy features that we provide our business customers to make sure they are kept up and running at all times.

Next off with our consumer clients we keep gaming voice and video traffic right at the top to make sure that MWEB customers can enjoy buffer free video and music streaming of the highest quality and lag-free gaming.

Next up we put the workhorse protocols in the middle of the pack. The browsing, emailing and patch downloading are not sensitive traffic and they can tolerate some shaping. This doesn't by any means make these activities go slowly and you'll probably never even realize that they're shaped, it just helps everything to run more smoothly, both on our network and for our customers.

Let's say for example you were downloading the latest version of IOS on your iPad and you decided to start streaming a video from YouTube on your smart TV. The traffic optimization would automatically adjust the speed of your IOS update to allow the video to stream smoothly.

Finally we all know that many of our customer enjoy their share of bulk downloads, which come in many different flavours. We certainly don't want to play policeman wit this type of activity, or stop customers from doing it, but we do know from experience that bulk downloading if unchecked can quickly take over the whole Internet. This is why, when we optimize, we give this type of traffic the lowest priority and it is quite normal for these types of activities to slow down at certain times of the day.

Throttling and Acceptable Usage Policies

The last factor that can affect ADSL speeds is the throttling that is in place to enforce our acceptable usage policy. Since the inception of our uncapped ADSL products several years ago we have tried several methods to enforce acceptable usage policies and we have found that throttling is by far the most sensible approach to take. It allows us to keep network costs down and effectively manage our bandwidth allocation, it curbs the behaviour of the handful of users who do tend to be very heavy handed with their download queues, without initiating unpleasant warning and abuse processes and most importantly it has absolutely no effect on the average customer who stays within the acceptable usage boundaries.

Without further discussion here is a quick summary of how the acceptable usage policy is enforced:

Reduce Speed when throttled

If you have managed to exceed the limits and gotten your self throttled then your overall speed will be temporarily reduced based on the product that you have.

These are the approximate reduced speed values at the time of publishing. Note these values are discretionary and are subject to change without notice :

Finally. If you are a potentially heavy downloader here are the throttle limits per ADSL product. Note once again that these are approximate discretionary values which are subject to change without notice:
