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.
