Solution
switched backbone:
Switched backbone networks use a star topology with one
device, usually a switch, at its center. The traditional
backbone circuit and set of routers or bridges is replaced
by one switch and a set of circuits to each LAN. The
collapsed backbone has more cable, but fewer devices.
There is no backbone cable. The backbone exists only in
the switch, which is why this is called a collapsed
backbone.
Advantages:
Switched backbones: Performance is improved. With the
traditional backbone network, the backbone circuit was
shared among many LANs; each had to take turns sending
messages. With the collapsed backbone, each connection

into the switch is a separate point-topoint circuit. The
switch enables simultaneous access, so that several LANs
can send messages to other LANs at the same time.
Throughput is increased significantly, often by 200% to
600%, depending upon the number of attached LANs and
the traffic pattern.
Disadvantages :
Switched backbone:Because data link layer addresses are
used to move packets, there is more broadcast traffic
flowing through the network and it is harder to isolate and
separately manage the individually attached LANs. Layer 3
switches can use the network layer address, so future
collapsed backbones built with layer 3 will not suffer from
this problem. Collapsed backbones use more cable and the
cable must be run longer distances, which often means
that fiber optic cables must be used. If the switch fails, so
does the entire backbone network. If the reliability of the
switch has the same reliability as the reliability of the
routers, then there is less chance of an failure. For most
organizations, the relatively minor disadvantages of cable
requirements and impacts of potential switch failure are
outweighed by the benefits offered by collapsed backbones
Routed backbone:
Routed backbonesmove packets along the backbone based
on their network layer address ( layer 3 address). The
