Western Trucking operates a large fleet of trucks that deliver shipments for commercial shippers such as food stores, retailers, and whole- salers. Their main headquarters building and sec- ondary building are shown in Figure 8-10. They want to upgrade to a faster network. Design a new net- work for them, including the specific backbone and LAN technologies to be used. Assume that the main office building is 170 feet by 100 feet in size and that the secondary building is 100 feet by 50 feet. The two buildings are 100 feet apart.
