FUNCTIONS

BUS  TOPOLOGY

vIt is a multipoint topology.

vOne long cable acts as a backbone to link all the devices in the network.

STAR  TOPOLOGY

vEach device has a dedicated point-to-point link only to a central controller.

vIt does not allow direct traffic between devices.

ring  TOPOLOGY

vEach device has a directed point-to-point line configuration.

vMessage will  be passed to each device until it reach the destination.

mesh  TOPOLOGY

vA mesh topology provides redundant communication paths between some or all devices.

vTwo categories of Mesh Topology :

Ø Full Mesh Topology :Normally use went we found a compelling reason to inner connect multiple location for direct connectivity to every other location.

Ø Partial Mesh Topology : At least one device maintain multiple connection to the other devices, however other connection do not have to be maintain directly to every other devices.

tree  TOPOLOGY

vA tree topology integrates the star & bus topologies in a hybrid approach to improve network  scalability.

hybrid  TOPOLOGY

vThe combination of two or more topologies.
