Abstract:
Nodes can run RPL in storing or non-storing modes for downward
routing. When a downward-bound packet traverses a node running in
storing to a node running in non-storing mode, there is a routing
pathology that makes the packet bounce between the two nodes. Due to
this pathology, the packet never reaches the destination if it lies
beyond these nodes in the multi-hop path. The solution is to mandate
that all the nodes parse and interpret source routing headers and
storing nodes to sometimes act like non-storing mode root.
