Network entity such as a LAN segment, host, or router that connects to a LightStream 2020 ATM switch via an edge card. Edge devices send and receive the data that passes through the ATM network.
1. A physical device thatis capable of forwarding packets between legacy interfaces (such as Ethernetand Token Ring) and ATM interfaces based on data-linkand network layer information. An edge device does not participate in therunning of any network layer routing protocol, but it obtains forwardingdescriptions using the route distribution protocol. 2. Any device thatisn't an ATM switch that can connect to an ATM switch.
an end point of a sensor- based architecture, such as a Radio-Frequency Identification (RFID) reader, a dry contact, an laser diode, carousel, scale, robotic picker, or indication devices such as light sticks or message boards
A physical device which is capable of forwarding packets between legacy interworking interfaces (e.g., Ethernet, Token Ring, etc.) and ATM interfaces based on data-link and network layer information but which does not participate in the running of any network layer routing protocol. An Edge Device obtains forwarding descriptions using the route distribution protocol.
A physical device which is used to forward packets between desktop network interfaces (such as Ethernet or Token Ring) and backbone transport facilities (such as ATM or trunked gigabit ethernet). This forwarding is based on either data-link or network layer information. Edge Devices typically reside in wiring closets (IDFs) and are the meeting point for the horizontal wiring (copper) and the riser cables (fiber).
A device that can pass packets between a legacy type of network such as an Ethernet network and an ATM network, using data-link layer and network layer information. An edge device does not have responsibility for gathering network routing information, but simply uses the routing information it finds in the network layer using the route distribution protocol.
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.
