Segment Switch Application

Figure 1-7 shows the BayStack 410-24T switch used as a segment switch to

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, 114 users have 40 Mb/s, four times the previous

bandwidth, while adding 22 dedicated 10 Mb/s connections. This configuration

can be extended to add more segments without degrading performance.
