Research on sharing buffer managing strategy of dynamic threshold based on short-packet first
基于短包优先的动态阈值共享缓存管理策略的研究*

To reduce the packet loss ratio and flow destroy ratio in the packet switching system with sharing buffer management, this paper proposes Sharing Buffer Managing Strategy of Dynamic Threshold Based on Short-Packet First, every packet sharing the same buffer. For SPBDT, we use two dynamic thresholds for each queue. According to the contrast of the length and the threshold of the queue, we could decide whether receive the new packet or not. Compare with DADT, SPBDT policy has lower packet loss ratio and lower flow destroy ratio in the more inputs and more outputs switching equipment.
