In delivering data with a large size, the proper use of the network is required. This paper proposes a new multicast routing method with multiservers. In this method, nodes in the network are grouped into high speed and low speed nodes. Delivery of content to groups of low speed nodes and high speed nodes are done separately from different servers. Simulation result was evaluated based on the social welfare. It proved that a good performance can be achieved by using this method.
