Both the dedicated circuit and frame relay approaches have merit. For the
final wide area topology, Fleet Call selected a combination of these
solutions. For the high-speed network backbone that provides mission-
critical connections, a frame relay network is used. For links to the tail sites,
point-to-point dedicated circuits running back to the backbone are suitable.
The wide area design is shown in figure 4.
Figure 4. Fleet Call WAN Topology
Each office site is equipped with 10Base-T networks running Novell NetWare
to provide local file and disk sharing. Except for electronic mail transfer, the
NetWare traffic is localized within each office, preserving the bandwidth of
the WAN for the TCP/IP host-directed traffic.
Fleet Call will use the HP OpenView Network Management system. It allows
Fleet Call to monitor and manage all the network devices that have IP ad-
dresses or can be queried with SNMP. This includes the routers, network
hubs, print spoolers, PCs running the PC/TCP software, UNIX workstations,
and Macintoshes running TCP software.
