摘要: 
本篇論文將針對ATM網路中具有自相似性的視訊,發展出回授式流量控制
器.此控制器的核心部份是由多重漏桶演算法所構成.我們假設,自相似交
通流量經由累加之後具有統計多工增益.,我們將同一個虛擬通道中的所有
漏桶予以整合,亦及共享各漏桶的漏失率及緩衝區,以期網路資源得以被更
有效地利用.

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.
