With this large address table, SPM port modules can serve the needs of medium-sized to large networks. The address tables are flushed periodically to update the network status and to purge any inactive stations from the tables. See the figure and table that follows:

Segment 1

Segment 2

(Inside of Hub)

Segment 1’s packets are forwarded when the destination addresses are NOT in its address table.

Segment 1’s packets are filtered when the destination addresses are in its address table.

2.Throughput Increase / Software Transparency

By selectively forwarding packets from the mixed-media hub’s ports (or hub stack’s ports) to the rear-connector port based on its switching logic, an SPM increases the available bandwidth for the users on both the hub side and the rear-segment side of the network. As shown in Figure 2.5b, it keeps the local traffic on each side contained, preventing unnecessary packets and bad packets from traveling to the other segment and using up bandwidth needlessly. This results in more available network bandwidth on both sides and a throughput increase for all users on both segments. An SPM needs
