优先级业务量管制机制及其性能模拟

Priority Traffic Policing Mechanisms and Their Perfomance Simulations

提出６种可以用来对含不同优先级别信元的业务流量进行管制的机制，它们彼此在信元缓冲器共享、令牌掠夺、先进先出，以及队头效应方面存在不同，通过模拟对其性能进行了比较，结果表明采用“缓冲器共享”、“前跳”和“令牌掠夺”的第６种机制具有最好的综合效果．

Six mechanisms for policing traffic with different priorities of cells are presented. They are different from each other in the following aspects: cell buffer sharing, token grabbing, FIFO and HOL effect. Their performance evaluations are obtained through simulations. Simulaiton results show that the sixth mechanism which uses buffer sharing, token grabbing and jumpahead policies reaches the best comprehensive performance.
