[Fwd: [IP] Japan facing bandwidth shortage due to take-up in broadband]
I wonder how much of this is bandwidth that could be saved by clamping down on worm traffic / assorted junk from zombies and open proxies etc, before investing in new bandwidth on a national scale - and in upgrading routers and other kit for that purpose.
And I do believe that a lot of the bandwidth for broadband (true broadband that is, not what the average US ISP would call "dsl" or "cable") there is online gaming traffic... bandwidth requirements for that would be increasing steadily if I don't miss my guess.

Prediction of Communications Crisis Prompts Japan's Telecom Ministry to
February 23, 2004 (TOKYO) -- Japan's Ministry of Public Management, Home
Affairs, Posts and Telecommunications (MPHPT) is taking the initiative
establish a study group in order to circumvent a potential
crisis that could occur in Japan due to a sharp increase in data
Predicting that the spread of broadband communications may cause
shortages in existing communications infrastructures as soon as five
from now, and strong possibilities of triggering interruptions, the
plans to launch countermeasures aimed at reinforcing the communications
infrastructure. The study group expects to release a midterm report this
According to the report, data communications traffic across the country
been expanded nearly 1,000 times as large as that observed in the last
years. If it continues to increase at this pace, the domestic data
communications traffic should reach as much as 1,024 times the current
volume in the next 10 years.
With the current facilities as they are, a simple calculation shows that
actual communications traffic will exceed the backbone's maximum
soon as five years from now.
That is not the only problem. Capacity limits of devices -- routers and
switches that constitute communications networks -- are coming within
In order to handle huge communications traffic without any delay,
large-capacity routers of more than 10Tbps are required. To deal with
growing data communications traffic, it is imperative to reinvest in the
communications infrastructure, such as an expansion of relay-network
capacities by adding new optical fibers and communications equipment.
