Abstract(in English) To provide predictive end-to-end QoS in the large-scale Internet, a network operation method has been studied which combines DiffServ (differentiated services) technology with traffic engineering using MPLS (Multi-Protocol Label Switching) technology. DiffServ cannot offer end-to-end QoS by itself, because it is a hop-by-hop relative-priority control. Therefore, traffic engineering support using MPLS routing is needed. In this paper, we assume EF (expedited forwarding) class which corresponds to voice traffic requiring path delay quality, and BE (best effort) class which corresponds to data traffic requiring throughput quality. And using QoS simulation, we evaluate MPLS routing methods, which are categorized based on routing algorithms and choice of E-LSP (class-independent route) and L-LSP (class-related route). The results show that the method for L-LSP which uses two routing algorithms depending on DiffServ classes can offer QoS required by the classes.
