Example operation of the network code of Section 4, with 
. The transmissions of all nodes in the time slots 
are depicted. Different transmissions by the same node are separated by a comma. Note, that the symbol transmitted at 
by the node with dotted border can be obtained by summing all transmissions from nodes with a dashed border in earlier time slots. All nodes in the interior of the network perform this simple coding operation.
