Performance Evaluation of Efficient Group Design Using Hierarchical MPLS

Summary Recnetly, 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. 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.
