  The last decade has witnessed an ever-growing user demand for a better QoS
(Quality Of Service) and the fast growth of connected devices still put high
pressure on the legacy network infrastructures. To improve network
performances, better manage the resources and have a greater control over
traffic transmission, intelligent routing procedures are increasingly demanded.
Modern applications in the dynamic context of new emerging networks have their
own routing requirements, in terms of set of metrics to consider, their
importance and thresholds to respect. The objective of this work is to design
an approach based on MCDM (Multi-Criteria Decision Making) to decide complex
routing problems when assuming threshold constraints on metrics. We give the
mathematical framework to capture such requirements and to decide the routing.
A case study is presented to advocate the benefit of using our approach.
