Network Aggregation Plan

With 24 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision domains), a Gigabit switch stack can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.

In the figure below, the 10/100/1000BASE-T ports in a stack of 48-port Gigabit Ethernet switches are providing 1000 Mbps connectivity through stackable switches. In addition, the switches are also connecting several servers at 10 Gbps.
