Performance Evaluation of Efficient Group Design Using Hierarchical MPLS

Recently, the demands of QoS(Quality of Service) and the traffic in network is increased. So, HMPLS(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 HMPLS setup cost. This paper, sets up the H-MPLS groups. The paper uses NS simulator in order to analyze the performance and traffic transfer times of each H-MPLS groups. In conclusion, one can find out the elevation of the traffic performance, by increasing a amount of links.
