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
