You have been asked to assess the LAN at a popular, but cash-strapped children’s museum. Visitors have complained that the video kiosk exhibits, which obtain their content from a server on the local network, are slow to respond and sometimes stall out. Meanwhile, museum staff members often wait several minutes to access large files or retrieve Web pages. The museum’s IT manager confesses that he hasn’t had the time or money to redesign the LAN, which was installed in 1999. It uses small, outdated switches and routers and only delivers 10-Mbps throughput to each client. The IT manager feels confident that he can convince management to support a network upgrade because it’s critical to continuing operations. He says the most important parts of the network are the 10 workstations that supply multimedia content to the exhibits, though it’s also important for the seven office employees to perform their jobs efficiently. He adds that the museum’s connection to its ISP was just upgraded, so it’s only the LAN that needs to be changed. What kind of LAN will you design for this company? Describe its backbone, its physical and logical topologies, what access method it will use, and what media and throughputs you recommend.
