Network Planning

Overview

A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition
a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important
building blocks for today's networking technology.
When performance bottlenecks are caused by congestion at the network access point (such as the network card for a high-volume
file server), the device experiencing congestion (server, power user, or hub) can be attached directly to a switched port. And, by
using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.
When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count.
However, a switch turns the hop count back to zero. So subdividing the network into smaller and more manageable segments, and
linking them to the larger network by means of a switch, removes this limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet network to significantly boost bandwidth while
using conventional cabling and network cards.

Application Examples

The switches are not only designed to segment your network, but also to provide a wide range of options in setting up network
connections. Some typical applications are described below.

Collapsed Backbone

The NXA-ENET8-2POE is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant
growth is expected in the near future. In a basic stand-alone configuration, it can provide direct full-duplex connections for up to
10 workstations or servers. You can easily build on this basic configuration, adding direct full-duplex connections to workstations
or servers. When the time comes for further expansion, just connect to another hub or switch using one of the Gigabit Ethernet
ports built into the front panel, or a Gigabit Ethernet port on a plug-in SFP transceiver.
In FIG. 9, the NXA-ENET8-2POE is operating as a collapsed backbone for a small LAN. It is providing dedicated 1000 Mbps full-
duplex connections to workstations and 100 Mbps full-duplex connections to power users, and 1 Gbps full-duplex connections to
servers.
