摘　　要：交换技术是一种采用软硬件结合的方式,主要利用硬件设备,将网络中传输的数据信息包直接转发到相应的目标地址的技术.透明网桥作为网络交换技术中的关键设备,对用户是透明的,其内部使用的是生成树算法.本文通过对透明网桥的生成树算法的全面分析,提出了几点改进办法.A network bridge is an abstract device that connects multiple network segments along the data link layer. An example of a bridge in a computer network is the network switch. A bridge forwards frames between the connecting networks on the basis of information contained in the data- link header. As Data- link Layer of the OSI Reference Model, bridge is transparent to Network - Layer protocols. （A bridge differs from a muter, which forward packets between different network topologies and determines the best path between the two. A muter operates at the Network Layer of the OSI Reference Model）The bridge also functions as a filter, discarding packets intended for the originating network and sending on packets intend for the destination network.
