Recnetly, the demands of QoS(Quality of Service) and the traffic in network is increased. So, H-MPLS(Hierarchical MPLS) network research what guarantees the scalability is in progress. But, the H-MPLS has a problem of increasing of groups and the links of these group's nodes. It happens a problem that is increasing of H-MPLS setup cost. In this paper, We setup the H-MPLS groups. We use NS simulator in order to analyze the performance and traffic transfer times of each H-MPLS groups. In conclusion, we can find out the elevation of the traffic performance, by increasing a amount of links.
