【摘要】 目前已证明，在同样大小缓冲区的条件下，基于中央排队的交换系统具有较好的性能．文中对在中央排队交换系统中如何实现多址传输及解决多址传输与单址传输冲突的方法进行详细描述，提出了一种称为具有输出缓冲和屏蔽优先级的单写单读方案，实现多址传输并解决多址传输与单址传输的冲突，降低信元丢失率和信元延时．最后给出该方案的仿真建模方法．更多还原

【Abstract】 It has been proved that center buffer based ATM switch offers better performance under conditions of identical memory size. Here described in detail are the approach to multicast cells and the way to solve the collision between multicast and unicast in switching system. A new solution to multicasting cells called single write and single read with output buffer and output mask, is put forward,thus avoiding cell loss, and reducing cell delay. Finally, the way to setup a model of simulation is also given更多还原
