Using the BayStack 450 10/100/1000 Series Switch1-20 302401-D Rev 00Segment Switch ApplicationFigure 1-7 shows a BayStack 450-24T switch used as a segment switch toalleviate user contention for bandwidth and eliminate server and networkbottlenecks. Before segmentation, 88 users had a total bandwidth of only 10 Mb/savailable. After segmentation, 92 users have 40 Mb/s, four times the previousbandwidth, while adding 22 dedicated 100 Mb/s connections. This configurationcan be extended to add more segments without degrading performance.Figure 1-7.
