PERFORMANCE ANALYSIS OF LEAKY BUCKET POLICING WITH PRIORITY MANAGEMENT IN ATM NETWORKS
-
摘要: 本文利用推广的流体流方法分析了具有优先级管理的ATM网漏桶监管器(PLB)性能.这种PLB将部分缓冲共享(PBS)的选择丢弃优先级管理策略用于业务监管,对高、低优先级信元区别对待,从而保证高优先级信元的低丢失率。文中针对突发业务分析了此种监管方案的性能.理论计算及仿真实验结果表明了该方案的有效性。通过性能分析可望选取合适的PLB参数进行有效控制。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.
