生成树协议在局域网中的应用

Configuration of Spanning Tree Protocol in Local Area Network

交换网络环路是为交换网络提供冗余链路时形成的,环路的存在导致了交换网络中广播风暴的产生,致使交换网络的MAC地址系统失效。这是冗余链路最大的问题所在,而为了避免单点故障引所起的网络中断,在网络当中又必须要求具备冗余备份链路。该文讨论生成树协议在具有冗余链路的交换网络中的工作实现,及随着网络应用要求而改进的生成树协议技术,即快速生成树协议和多生成树协议的工作实现,从而达到在交换网络中既保障了网络冗余链路,又避免了环路危害的目的。

Switched network loop is a redundant link for the switching network, which causes the generation of broadcast storm inthe switching network. The MAC address system of the switched network is invalid. This is the biggest problem of redundant link,and in order to avoid the single point of failure caused by the interruption of the network, in the network must be required to haveredundant backup link. In this paper, we discuss the implementation of spanning tree protocol in switched networks with redundantlinks, and the work of improving the network application requirements, namely, the fast spanning tree protocol and multi spanningtree protocol.
