【摘要】 讨论了一定监控算法下最差通过流的概念，强调了最差通过流的参数特性是评价一种业务监控算法的最重要指标之一．对基本漏桶和缓冲漏桶算法进行了比较．基于改善最差通过流特性及减小信元缓冲器数量的考虑，提出了二级漏桶算法．分析和计算机仿真结果表明：本算法下最差通过流特性较缓冲漏桶算法有所改善，同时所需缓存器数量也比缓冲漏桶算法减少．更多还原

【Abstract】 The concept of worst case source and worst case traffic for a policing algorithm is discussed. Emphasis is given to the importance of worst case traffic analysis in performance evaluation of a policing mechanism. Basic leaky bucket and buffered leaky bucket are analysed and compared for worst case traffic. A new algorithm of two stage leaky bucket is proposed. Simulation results show that the algorithm is superior to the buffered leaky bucket in worst case traffic and less cell buffers are needed.更多还原
