Multicast plays an important role in supporting a new generation of applications. At present and for different reasons, technical and non-technical, multicast IP hasn't yet been totally adopted for Internet. During recent years, an active area of research is that of implementing this kind of traffic in the application layer where the multicast functionality isn't a responsibility of the routers but that of the hosts, which the authors know as Multicast Overlay Networks (MON). In this paper, routing in an MON is put forward as a Multi-objective Optimization Problem (MOP) where two functions are optimized: the total end to end delay of the multicast tree and the maximum link utilization.
