In this thesis we proposed a feedback rate regulator for self-
similar VBR traffic in ATM networks, based on multiple leaky
buckets (MLB) mechanism.A basic assumption was made that the
multiplexing gain does exist for aggregated self-similar VBR
traffic. Therefore, unlike the conventional leaky bucket (LB),
the leaky rate and buffer capacity oa all LBs are shared in the
smae virtual path, in order to use network resouces more
effectively. In our mechanisms, the leaky rate and buffer
capacity of ecah LB are dynamically adjusted base on the buffer
occupancy. To validata the performance of our mechanisms, ten
real world MPEG1 traffic traces and synthesizeself-similar data
series are used in our experiment. The simulation results show
that the cell loss rate has three or more than ten thousand
times improvement comparing to the conventional leaky bucket
method. Moreover, when the protection policy intregrated with
feedback rate regulator is added to the MLB, it can totally
prevent the malicious sources from degrading the quality of
services of all established conncetions.
