Figure 7 shows the CoreBuilder 9000 ATM Enterprise Switch deployed with two
servers and numerous workstations.
Figure 7 The CoreBuilder 9000 ATM Enterprise Switch in a Simple Workgroup
Each server and workstation has an ATM adapter, allowing full rate use of
IP over ATM and eliminating the need for any other network protocol.
The CoreBuilder 9000 ATM Enterprise Switch has up to 22 OC-12/STM-4
or 88 OC-3/STM-1 MMF or SMF interface ports, allowing connections or
a large number of servers and workstations.
Multiple Switch IP
Routed Network
In addition to the simple workgroup configuration described previously,
you can configure a Classical IP ATM network to contain multiple
CoreBuilder 9000 ATM Enterprise Switches at the core, which you
segment into IP subnet works. A router supporting ATM connectivity with
RFC-1577 compliance provides connectivity between these subnet works.
The NETBuilder II router also supports connectivity to non-ATM protocols
through the IP layer by converting the IP over ATM protocol to Ethernet,
Token Ring, FDDI, and so forth. In addition, the router can be used for
WAN connectivity.
Figure 8 shows a network incorporating multiple CoreBuilder 9000 ATM
Enterprise Switches and a NETBuilder II router, as well as access to a
Network Management Station (NMS) for SNMP management (for
example, Transcend
®
ATM Manager) via a hub.
