Rings

A simple ring is just a linear array with the end nodes linked.







It is equivalent to a 1D mesh with wraparound connections. One drawback to this network is that some data transfers may require N/2 links to be traversed e.g. A and B above ( 3 ).
This can be reduced by using a chordal ring This is a simple ring with cross or chordal links between nodes on opposite sides
