摘　　要：网络交换机对广播报文的处理即所有端口对该报文复制转发,若此时网络上有广播报文,则环路的形成会导致广播报文永远无法消除且被复制的越来越多,并在环形网络中形成广播风暴。因此,分析了冗余网络存在的问题,重点介绍了生成树协议(Spanning Tree Protocol,STP)算法的工作原理和核心思想,并提出STP算法在ARM9200处理器与BCM53115交换芯片上实现的具体方案。最后,通过组网测试验证了STP算法能够解决广播风暴问题的正确性。The processing of broadcast messages is all the ports in the network switch for copying and forwarding,if there are broadcast messages on the network at this time,then,the formation of the loop will lead to the broadcast messages can never be eliminated and more and more copied,forming a broadcast storm in the ring network.In this paper,the problems existing in redundant network are analyzed,the working principle and core idea of Spanning Tree Protocol(STP)algorithm are introduced,and the specific scheme of STP algorithm in ARM9200 processor and BCM53115 exchange chip is proposed.Finally,the correctness of STP algorithm in solving the problem of broadcast storm is verified.
