Abstract

In the Input Buffer Switch using the intial stage FIFO memory structure, It has pointed the Throughput limitation to the percent of 58.6 due to HOL(Head of Line) blocking in the DBP(Dedicated Buffer with Pointer) method, During that time, To overcome these problems, The prior papers have proposed the complicated Arbitration algorithms and Non-FIFO memory structures. and These showed the improved Throughput. But, Now, To design high speed ATM Switch which need to the tens of Giga bit/s or the tens of Tera bit/s. It has more difficulty in proceeding the priority of majority and the complicated Cell Scheduling, because of the problem in operating the control speed of the ratio of N to scanning each port and scheduling the Cell. In this paper, To overcome these problems, We could show more the improved performance than the existing DBP Window policy to design high speed ATM Switch.
