alleviate user contention for bandwidth and eliminate server and network
bottlenecks. Before segmentation, 88 users had a total bandwidth of only 10 Mb/s
available. After segmentation, 92 users have 40 Mb/s, four times the previous
bandwidth, while adding 22 dedicated 100 Mb/s connections. This configuration
can be extended to add more segments without degrading performance.
