Edge Device

Edge devices are routers, switches, routing switches, integrated access devices (IADs), multiplexers, and a variety of metropolitan area network (MAN) and wide area network (WAN) access devices that provide entry points into enterprise or service provider core networks. On an enterprise network, edge devices may connect Ethernet and token ring local area networks (LANs) to an Asynchronous Transfer Mode (ATM) backbone, where the ATM network provides a bridge between the edge networks. Edge devices also provide connections into carrier and service provider networks.
