摘要: 本文利用推廣的流體流方法分析了具有優(yōu)先級管理的ATM網(wǎng)漏桶監(jiān)管器(PLB)性能.這種PLB將部分緩沖共享(PBS)的選擇丟棄優(yōu)先級管理策略用于業(yè)務監(jiān)管,對高、低優(yōu)先級信元區(qū)別對待,從而保證高優(yōu)先級信元的低丟失率。文中針對突發(fā)業(yè)務分析了此種監(jiān)管方案的性能.理論計算及仿真實驗結(jié)果表明了該方案的有效性。通過性能分析可望選取合適的PLB參數(shù)進行有效控制。Abstract: The performance of leaky bucket policer with priority management (PLB) in ATM networks is ananlyzed using extended fluid flow method. This PLB scheme introduces PBS selective discarding priority management into service policing. It guranties lower loss probability for high priority cells. The analysis and numerical experiments show that this scheme is useful. By the performance analysis, suitable PLB parameters for efficacious control may be obtained.
