摘　　要：交换技术应用于企业网络包括局域网交换和广域网交换.局域网交换技术通过在不同网段上的节点之间建立高速的交叉连接,使网络资源由共享变成独占方式,以消除固有的阻塞.广域网交换使数据、话音及视像等各种应用之间可根据需要实时地调节带宽的使用率,并简化了信息传送的步骤.介绍了帧中继、X.25、ATM、第三层交换等交换技术在企业网络中的应用情况.Switching technique's application in enterprise network includes two aspects, i.e. LAN switching and WAN switching. LAN switching technique turns the sharing of network resource into dedicated manner to guarantee the bandwidth user needed through establishing high - speed cross connections between nodes in different network segments. WAN switching realizes the real-time on-demand bandwidth allocation between various applications such as data, voice and video and simplifies the information transfer steps. LAN switching and WAN switching make up the new generation of enterprise network, i.e. switching enterprise network, which consists of WAN switching equipment, LAN prime switching equipment (layer 3 switching equipment) and network segment switching equipment.
