We propose a new Dynamic Multicriteria Alternative Routing (DMAR) method that applies to reservation-oriented networks. DMAR combines a dynamic alternative routing scheme with a periodic update of alternative paths according to a multicriteria algorithm that aims to balance the traffic between traffic flows in single-service networks and also between services in multi-service environments. We conducted extensive simulations to compare the performance of DMAR with that of other reference alternative routing schemes in single- and multi-service networks with several topologies and load scenarios, namely with non-stationary traffic. We show that DMAR efficiently adjusts to traffic changes while often presenting better network performance than the reference alternative routing schemes, particularly in the multicriteria sense.
