Anyone have any experience with these Anagran flow routers? Are they that much of a departure from traditional routing that it makes a big difference?
There's no difference in routing per se. Rather it's in-band signaling of QoS parameters to provide feedback to queue management.
I haven't done a lot of research into flow-based routing at this point, but it sounds like this would be similar to the MPLS approach, no?
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.
