===Mesh===

A mesh topology consists of links between only two nodes, but each node has dedicated links to multiple other nodes.  In a full mesh, each node has a dedicated link to every other node, thus the number of links will climb exponentially with the number of nodes.  This is the most expensive topology for a given number of nodes, but also has the highest bandwidth.  In partial meshes, the nodes have links only to some of the other nodes.  This provides a slightly less expensive network with lower, but still significant, bandwidth.  A mesh with only two or three nodes is indistinguishable from a ring.
