  Flow-Aware Multi-Topology Adaptive Routing (FAMTAR) is a new approach to
multipath and adaptive routing in IP networks which enables automatic use of
alternative paths when the primary one becomes congested. It provides more
efficient network resource utilization and higher quality of transmission
compared to standard IP routing. However, thus far it has only been evaluated
through simulations. In this paper we share our experiences from building a
real-time FAMTAR router and present results of its tests in a physical network.
The results are in line with those obtained previously through simulations and
they open the way to implementation of a production grade FAMTAR router.
