There's no difference in routing per se.  Rather it's in-band
signaling of QoS parameters to provide feedback to queue management.

There is no setup phase.  Signaling is in-band and periodic.  The
theory is that every once in a while a control packets is sent, with
the same src/dst as the regular data packets.  Whatever paths the
packets take, the control packets will take the same paths.
