1.2.4 High Performance Switching Example
The Switch is ideal for connecting two networks that need high bandwidth. In the following example, use
link aggregation (trunking) to connect these two networks.
Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most
people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring
your network and complex maintenance. The Switch can provide the same bandwidth as ATM at much
lower cost while still being able to use existing adapters and switches. Moreover, the current LAN
structure can be retained as all ports can freely communicate with each other.

1.2.5 IEEE 802.1Q VLAN Application Examples
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical
networks. Stations on a logical network belong to one or more groups. With VLAN, a station cannot
directly talk to or hear from stations that are not in the same groups unless such traffic first goes through
a router.
