Segment Switch Application - Nortel 325-24T Configuration Manual

Segment switch application

Figure 12 and
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, 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.
