An interesting tidbit the list. ZDNet technical editor George Ou
reported today on his trip to Capitol Hill, where he participated
in a panel on network management issues. Also on the panel was an
official from Japan, which has more high bandwidth links to the
home than any other nation on Earth. George reports on Japan's experience:
Next up was Mr. Haruka Saito from the Embassy of Japan. Mr. Saito
explained that Japan had been studying and debating the issue of
Network Neutrality in Japan for about a year and a half and he
offered a lot of hard data gathered in Japan. Japan is one of if
not the most connected nation in the world when it comes to
broadband deployment with 100 Mbps fiber deployments and despite
this abundance of capacity, even I was shocked that they were
running into congestion problems.
When the traffic chart was broken down in to color-coded regions
showing application usage, P2P easily ate the lion's share of
resources and dwarfed everything else on the chart. Mr. Saito
went on to explain that 1% of the users primarily through P2P
consumed around 50% of the total capacity and this pretty much
mirrors every other study I've seen elsewhere in the world
regardless of capacity. The debate in Japan was who was going to
pay for this excessive usage and whether the heaviest users should
start paying more money.
In short, the Japanese experience is that P2P usage grows with
added capacity so that it continues to consume a disproportionate
share of available bandwidth.
For the complete text of George's article, see:
[ This is interesting, but doesn't really move the ball. Within a
decade, perhaps in just a few years, we may well see *legal*
video as the biggest single consumer of bandwidth. Whether
transmitted by P2P or some other means, consumers are going to
demand access to the vast range of video services -- many of
which will be HD -- that are even now being rapidly deployed.
ISPs will view these as direct competition to their own PPV and
free entertainment offerings. Then we're not talking about the
*relatively* small universe of P2P fans, but large streams
pouring in and out of the majority of consumer homes.
P2P as bogeyman isn't going to fly. Just as programs have expanded
to fill available memory and data expands to fill available disk
space, applications -- many of which will be encrypted -- will expand
into available bandwidth. Call the applications what you will,
but it won't matter.
This all implies that concentrating controls on a per-application
basis will be hopeless in the end, and that overall bandwidth
utilization and fairness is a much more fruitful area for attention.
