CableForum.co.uk has details on a traffic shaping trial underway in the Swansea area.
ntl:Telewest is experimenting with a system that will limit its 10Mbps service customers down to a maximum of 5Mbps between 4pm and midnight if the individuals usage exceeds what ntl:Telewest considers is fair under the firms Fair Use Policy (FUP).
Figures from ntl:Telewest suggest that around 10% of its customers are actually using 70% of the available bandwidth capacity at any time. If the company goes ahead with faster products like 20Mbps and 50Mbps which are believed to be under trial, it is possible this 70% may increase further. Estimates from the company suggest that over 95% of customers should not notice the new system.
From what we can see it looks like the restriction is a daily thing, which should mean those affected do not need to wait too long before downloads can resume at faster speeds.
What is interesting to those following the growth of usage policies in the UK, is that the ntl:Telewest move is not linked to any BT Group pricing, since the cable broadband network does not use BT Central products. The BT Centrals are a key component in the BT Wholesale ADSL products and can be a significant cost for broadband providers.
