Abstract

Today's networking environment is characterized by significant traffic variability and squeezing profit margins. An adaptive and economics-aware traffic management approach is needed to cope with such environment. An adaptive traffic management system is proposed that acts on short timescales (from minutes to hours) and employs an economics-based figure of merit to rellocate bandwidth. The tool works in an MPLS context. Both underload and overload deviations from the optimal bandwidth allocation are sanctioned through the economical evaluation of the consequences of such non-optimality. A description of the traffic management system is provided together with some simulation results to show its operations.
