| Abstract(in English) | Recently IP networks are being urged to support various traffic requiring different Quality of Service (QoS). We proposed a QoS control architecture that provides optimal resource assignment for traffic requiring QoS guarantee. In this paper, we propose an algorithm, which is applied to QoS server in the proposed architecture, to calculate optimal routing paths for traffic demands. We employ two-stage design, which consists of "route selection" and "LSP assignment". "Route selection" chooses eligible routes between each ingress-egress edge pair prior to resource requests arrival. After resource requests are received, "LSP assignment" selects optimal routes. We formulate LSP assignment as an integer programming problem and can select objective functions according to characteristics of services. Finally, we evaluate the LSP assignment scheme. The result shows the proposed scheme improves accommodation efficiency. |
