21、更高的性能和更有效的传输效率。 帧中继广域网的设备分为数据终端设备(DTE)和数据电路终端设备(DCE)，Cisco路由器作为 DTE设备。帧中继技术提供面向连接的数据链路层的通信，在每对设备之间都存在一条定义好的通信链路，且该链路有一个链路识别码。这种服务通过帧中继虚电路实现，每个帧中继虚电路都以数据链路识别码(DLCI)标识自己。DLCI的值一般由帧中继服务提供商指定。帧中继即支持PVC也支持SVC。 帧中继本地管理接口(LMI)是对基本的帧中继标准的扩展。它是路由器和帧中继交换机之间信令标准，提供帧中继管理机制。它提供了许多管理复杂互联网络的特性，其中包括全局寻址、虚电路状态消息和多目发
