Collapsed Backbone; Network Aggregation Plan - Nortel BES50GE-12T PWR User Manual

The BES50FE-12/24T PWR and BES50GE-12/24T PWR 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 in the following sections.

Collapsed backbone

The switches are ideal for mixed Ethernet, Fast Ethernet, and Gigabit
Ethernet installations where significant growth is expected in the near future.
You can easily build on this basic configuration, adding direct full-duplex
connections to workstations or servers. When the time comes for further
expansion, you can connect to another hub or switch by using one of the
Ethernet ports built into the front panel.

switch is operating as a collapsed backbone for a small LAN. It is providing
dedicated 10/100/1000 Mbps full-duplex connections to workstations, PoE
devices, and servers.

Network aggregation plan

With 12/24 parallel bridging ports (that is, 12/24 distinct collision domains),
the switches can collapse a complex network down into a single efficient
bridged node, increasing overall bandwidth and throughput. In the figure
