In order to ensure the evolution of the Internet, it is essential
that to understand the effects of growing residential traffic.
Focused on high penetration rate of fiber-based broadband access,
this paper firstly reported aggregated traffic measurements collected
over 21 months from sever ISPs covering 42% of the Japanese
residential traffic which increased 37% in 2005. Further, paper
investigated residential per-customer traffic in one of the ISPs by
comparing DSL and fiber users, heavy-hitters and normal users, and
geographic traffic matrices.

Cooperated with ISPs, data was collected. It's important to draw a
strict line for grouping: residential/business and domestic/
international, on the global Internet. The result were obtained by
aggregating all traffic logs provided by the seven ISPs. The growth
of residential broadband traffic has already contributed to a
significant increase in commercial backbone traffic. In the study,
residential broadband traffic accounts for two thirds of the ISP
backbone traffic and is increasing at 37% per year, which will force
significant reevaluation of the pricing and cost structures of the
ISP industry.

The study was furthered to residential per-customer traffic in one of
the ISPs, and authors investigated differences between DSL and fiber
users, heavy-hitters and normal users. The result is that a small
segment of users dictates the overall behavior. The distribution of
heavy-hitters is heavy-tailed without a clear boundary between heavy-
hitters and the rest of users. In the geographic traffic matrices,
authors indicated that a surprisingly large portion of traffic is
domestic communication where both ends and either domestic
residential users or other domestic address. The possible explanation
is language and cultural barriers. This could be common to other non-
English speaking countries to some extent.

This paper is also a research work based on trace and measurement.
The work is focused on the networks in Japan with the special
characteristic. There are some implication The increase of the
Internet traffic may be caused by new Internet content delivery
systems, like P2P file-sharing system. That is also the reason why
the peak hour changes from daytime to evening. In fact, the current
total traffic volume is heavily impacted by extreme heavy-hitters so
that a slight change in the algorithms or charging policies could
have a significant impact to backbone traffic. So, how to control the
heavy-hitters is very important. Another problem is this paper is
that the traffic from external international is small because the
language and culture. So does the research in this paper make sense
to analyze the impact of the growth in residential user-to-user traffic?
