The traditional design for wide area networks uses point-to-point dedicated
circuits. Dedicated circuits provide guaranteed bandwidth with high perform-
ance. With point-to-point circuits, Fleet Call could still implement the two-
tiered network described above. However, the point-to-point circuits offer
only a single circuit on the backbone, so Fleet Call would need to implement
a meshed network of multiple point-to-point circuits to achieve any kind of
link redundancy. A sample mesh network is shown in figure 2.
Figure 2. Point-to-Point Meshed Network
Circuit costs are based on distance, and Fleet Call’s wide geographic
dispersion would mean sizable monthly circuit costs to effectively run a
meshed network between the backbone sites. In addition, Fleet Call would
be solely responsible for the troubleshooting and problem isolation in a
point-to-point circuit network. This requires a higher level of technical
sophistication and knowledge from the Fleet Call network staff.
