Bridging Or Fiber Optic Uplink Example Application; High Performance Switching Example - ZyXEL Communications XMG1930 Series User Manual

1.2.3 Bridging or Fiber Optic Uplink Example Application

In this example, the Switch connects 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 through the Switch.
You can provide a super-fast uplink connection by using a Gigabit Ethernet or SFP port on the Switch.
Moreover, the Switch eases supervision and maintenance by allowing network managers to centralize
multiple servers at a single location.

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.
This helps you switch to higher-speed LANs without the need for replacing all existing Ethernet cables
and adapter cards, restructuring your network and complex maintenance.
