Sample ATM Network
D-3
Hardware Devices
Bay Networks provides various ATM hardware devices. Each of these devices
provides a different form of access within the ATM network. The ATM sample
network in this appendix uses the following Bay Networks ATM hardware
devices:
LattisCell switches
EtherCell switches
Backbone Node containing an ATM ILI pair
In addition to the Bay Networks equipment, the example requires UNIX
workstations to operate ATM network control software.
Function of the LattisCell Switch
Working in conjunction with network control software, the LattisCell switch acts
as the backbone of the ATM network (refer to Figure D-1). Multiple LattisCells
can interconnect using network-to-network interface (NNI) links. These
interconnecting LattisCells form larger ATM networks called ATM domains.
In addition to linking together with other switches, the LattisCell can also connect
to user-to-network interface (UNI) clients. UNI clients (for example, routers,
hubs, servers, and workstations equipped with ATM interfaces) reside on the edge
of an ATM network. Some of these UNI clients (that is, the routers, hubs, and
servers) can connect to other local or wide area networks.
For additional information regarding LattisCell features and how to install and use
the LattisCell, refer to Using the Model 101xx LattisCell ATM Switch.
