摘要: 在本論文中,主要提出了一種新的參數控制機制:``EWMA-II''。它彌補了
漏桶 (Leaky Bucket; LB) 用者不佳的監測能力。EWMA-II 機制的主要功
能 均叢聚長度。同時,若使用者因平均叢聚長度增加導致平均封包率上升
時,EWMA-II 機制亦將會獲得一個較 LB甈陛C它的效能分析我們將從數值
方法及計算機模擬兩方面來探討。 EWMA-IID常簡單,因此若EWMA-II 機
制與兩級的 LB責最大封包率的監測,另一級負責 □,我們將可獲得一個完
整的參數控制機制的架構,足以監測任何語音封包的使用者。 □探討了預
支型參數控制機制的效能,包括``預支型滑動視窗機制'' 窗機制''及``保
留-預支型跳躍視窗機制''。同時我們亦探討了非法使用 的變化種類,並
逐一對LB機制及指數加權移動平均(Exponentially Average; EWMA) 機制
做測試,最後我們對Turner 先生[15]所提出的 W寬配置法則及使用參數控
制做了修改,使其更符合實際系統的執行。
In this thesis we propose a new policing mechanism called EWMA-
II compensates the policing capability of Leaky Bucket scheme
topliant sources for which the peak rate and mean rate are
compliant whilelength is over contract. The main feature of
EWMA-II is to police the of a source. Also, when the mean rate
of a non-compliant source increases due to the increase of its
mean the EWMA-II policing scheme can achieve a very good
static behavior and a fast dynamic behavior. The performance of
EWMA-II mechanism is studied by numerical simulation results.
The hardware implementation of EWMA-II is Hence, if EWMA-II is
cascaded with two stages of Leaky Bucket (one policing peak
rate, the other policing mean rate), we any type of non-
compliant on-off sources to prevent network In the rest of this
thesis, we study some other new policing including ``Preuse
Moving Window''(PMW)、``Preuse Jumpingnd ``Reserve Preuse
Jumping Window''(RPJW). Also we classify the non-compliant
sources, and test the performance of LB and EWMA by these
sources to both mechanisms. Finally, we modify theation
algorithm and usage parameter control mechanism for data
packets Turner[15] to make it practical for real systems.
