【摘要】 提出了一种用于分组交换机中的缓存管理算法DT+SMA,该算法把DT和SMA结合起来,具有两者的优点。通过理论分析和仿真,得知在单优先级情况下DT+SMA比SMA的公平性更好,在多优先级情况下SMA比DT更易于实现,而且同时也能获得和DT相近的性能。更多还原

【Abstract】 In this paper a new buffer management scheme called DT+SMA is presented. This scheme combines sharing with minimum allocation (SMA) and dynamic threshold (DT) arithmetic,and we find it has the benefits of both DT and SMA. Through analysis the scheme in theory and simulation we can see that actually DT+SMA is better than SMA in fairness in single priority, and is easier to apply in multiple priorities model than DT when achieving the similar performance with DT.更多还原
