[[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.

you may want to look at the relationship between the japanese
government and the industry, and the various societal players
in between, before taking this at north american face value.

but 100meg ether to the home and office (in the urban centers)
and more innovative use of media have fostered much faster
increases of bandwidth needs in japan and korea than in north
america.

and shuresh, when you have some good automated technology for
"clamping down on worm traffic / assorted junk from zombies
and open proxies etc," i suspect many folk in those countries
and the rest of the world will deploy it or something like it.
in the meantwixt, our sympathies that your monopolistic telco
environment has not fostered enough bandwidth deployment that
your country could become a worm ... problem :-).

Heh, if there was one such, I'd deploy it .. at least to sleep peacefully at night if not to retire rich on the proceeds :slight_smile:

The monopolistic telco was a few years back. Right now there are a bunch of outfits large enough to provide (sort of) DSL - 512k .. and quite a few fat pipes coming into India. [one of which, Flag Telecom, was recently bought by one of the Indian telcos - Reliance Infocomm]

If there was no worm problem yet, I guess there will be now.

With the current facilities as they are, a simple calculation shows that
actual communications traffic will exceed the backbone's maximum
capacity as
soon as five years from now.

Since when is this is a good indicator? If we ignore any of the growth in facility capacity in the last 5 years, wouldn't we all be in capacity -plus situations right now? I know we are moving more than our total capacity from 5 years ago.

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.

Sounds like a great place to deploy an HFR-class router if you had to do it this year. In 5 years, a PC might be able to do it.

I suggest that folks re-read and heed the words of Sage Bush. This announcement is simply official marketing
to support a few facts: a) the government is officially acknowledging the exponential growth of the Internet,
something that all here understood long ago, b) the government is now supporting the development of a router
in Japan and this is the rationale for them to provide governmental support for the 'lucrative' core router
market.

This would depend on the netcode of the engines involved, but historically
it's always been relatively low throughput per-client but high pps.

P2P decimating transit links is more likely to be the offender imo.
