Nortel Networks 10BASE-T manual Segment Switch Application

Using the BayStack 410-24T 10BASE-T Switch

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.
