Most of the Spanning Tree Algorithm(STA) failures occur due to the excessive loss of BPDUs causing the blocked ports to transition to forwarding mode.

大多的生成树算法（STA）失败发生由于过多的丢失BPDU导致阻塞端口转换为转发模式。

This scheme greatly decreases the possibility of loss and duplication packets by a number of measures including BS buffering, forwarding mechanism and duplication elimination mechanism etc.

该方案通过基站缓冲、前向发送机制和重复包消除机制等措施，极大地减少丢包和重复的包。
