Chapter 1 Introducing the Switch

1.1.2 Bridging Example

The Switch can connect different company departments (RD and Sales) to the corporate
backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks.
All users that need high bandwidth can connect to high-speed department servers via the
Switch. You can provide a super-fast uplink connection by using a Gigabit Ethernet/mini-
GBIC port on the Switch. Moreover, the Switch eases supervision and maintenance by
allowing network managers to centralize multiple servers at a single location.

1.1.3 High-performance Switched Example

The Switch is ideal for connecting two networks that need high bandwidth. 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.
In the following example, two Switches use trunking to connect two networks.
