With much debate circulating about how to manage high-bandwidth services, one analyst has explained providers' problems.
Commentating on the PlusNet blog, Dave Tomlinson has recently offered a breakdown of some of the costs associated with offering high-speed broadband services.
Technology columnist Charles Arthur at the Guardian has called it a "fascinating explanation of the real costs" faced by UK internet service providers (ISPs).
Figures cited include a monthly breakdown of supplying 200,000 people with broadband services, which Mr Tomlinson notes can cost ISPs as much as £1.7 million.
These costs arise from the monthly line rental fees that many ISPs pay BT to connect customers to telephone exchanges.
Cost problems highlighted by recent debates about the success of BBC's iPlayer and similar services are also enumerated, with customers using high-bandwidth services such as video streaming and online gaming found to cost ISPs as much as £150 each per month.
The BBC announced recently that its iPlayer service saw a 66 per cent increase in video-streaming volumes since December 1st.
