Campus Configuration

The section gives an example of ATM within a campus environment. The diagram shown in Figure 5-2 on page 5-3 demonstrates a balance between cost and performance requirements.

Building A shows how you can concentrate IBM 8721 Nways Ethernet LAN Switch Model 612 and 624 devices using an IBM 8271 Nways Ethernet LAN Switch Model 712. All traffic internal to Building A is switched over Fast Ethernet. In addition, an ATM link to the campus backbone provides high speed access to remote services.

Building B shows how you can configure a building in a cost efficient manner, while retaining connectivity to the campus ATM network.

Only one ATM Module is required to connect the IBM 8271 Nways Ethernet LAN Switch Model 624 and Switch Model 524 devices to the ATM network. This provides connectivity for 48 Ethernet ports to the ATM backbone.

Building C shows you a building similar to Building A, but with additional campus-wide, high performance access to directly connected ATM servers.
