Graph of non-circular that briefly DODAG be reincarnated, a graph is just a root. In other words, all the directions just to a node, i.e. the root of the graph leading up. From the graph DODAG in the algorithm, routing RPL in the network such as the Internet of things is used.

The Roots on the graph (DAG) to the node are applied, that no mane, the output is not.
