Abstract--This contribution aims at performing a longitudinal
study of the evolution of the traffic collected every day for
seven years on a trans-Pacific backbone link (the MAWI dataset).
Long term characteristics are investigated both at TCP/IP layers
(packet and flow attributes) and application usages. The analysis
of this unique dataset provides new insights into changes in traffic
statistics, notably on the persistence of Long Range Dependence,
induced by the on-going increase in link bandwidth. Traffic in the
MAWI dataset is subject to bandwidth changes, to congestions,
and to a variety of anomalies. This allows the comparison of their
impacts on the traffic statistics but at the same time significantly
impairs long term evolution characterizations. To account for this
difficulty, we show and explain how and why random projection
(sketch) based analysis procedures provide practitioners with an
