Abstract: IP multicast is not widely deployed yet over Internet.One of the important reasons is the scalability problem of the multicast forwarding states.Aggregated multicast is a new technology to reduce multicast forwarding states，which aims to force multiple groups to share a single distribution multicast tree，so as to reduce the number of trees in the network，consequently，forwarding state is reduced，and thus the performance of multicast network can be improved.This paper utilizes genetic algorithm to solve aggregated multicast.The simulation results show that this algorithm has a great effect on the aggregated performance.

Key words: aggregated multicast, minimal set cover, genetic algorithm, fusion operator
