2.4 Applications
Magnum 500-Series Switching Hubs offer a great deal of performance and
flexibility, and are easily used in a variety of ways including client/server applications,
departmental networks performance upgrades and collapsed backbone applications.
Example 1 : Magnum 508
In a typical 10Mb network performance upgrade, multiple cascaded 10Mb hubs
connect all networked devices using one 10Mb traffic domain. The Magnum 508
Switching Hub provides eight 10Mb traffic domains for increased performance. It
connects all 10Mb equipment, hubs and servers, in the existing network while providing
full 10Mb bandwidth to the network segment on each separate port.
The Magnum 508 switch filters and forwards packets from one segment to
another, containing the local traffic and allowing only the packets which need to be
forwarded to go outside to the appropriate other segments. This provides several 10Mb
traffic domains rather than only one as before, greatly increasing performance. This is
ideal for a central departmental switch that has branches out to workgroup and/or
Personal Hubs

with users attached, and provides dedicated 10Mb ports for commonly
used servers. Figure 2.4 illustrates this example.
