using fBm, you can obtain self-similar 'time series' (and it will be used
for "rate" soocastic process(serieses of throughput)) , but what we
want to obtain is 'point　process' (a couple of timestamp and packet size).

So, if you want do synsetize self-similar traffic, you have to think
about how to use "self-similar time serieses".

I think aggregation of Pareto On/Off traffic is good for synthesizing
self-similar trarric.
