Mesh network

In this structure, there is random connection of nodes using communication links. In real life, however, network connections are not made randomly. Network lines are expensive to install and maintain. Therefore, links are planned very carefully after serious thoughts, to minimize cost and maintain reliable and efficient traffic movement. A mesh network may be fully connected or connected with only partial links. In fully interconnected topology, each node is connected by a dedicated point to point link to every node. This means that there is no need of any routing function as nodes are directly connected. The reliability is very high as there are always alternate paths available if direct link between two nodes is down or dysfunctional.
