1.4.3 High Performance Switched Example
The switch is ideal for connecting two networks that need high bandwidth. In the following
example, use 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.
