Network Topology - Mesh and Partial Mesh
Mesh
This network topology is quite expensive to setup, because it requires too much cable… because every node is physically connected to all the other nodes on the network, with cable. This type of network is used in WAN’s (Wide Area Networks). When you add a new node, you have to connect it to all the other nodes on the network, therefore the more nodes you add, the more cable.
But in some cases particular links can be removed, and you will still have low risk of network failure, this is called Partial Mesh.
