碩士 === 國立中央大學 === 資訊工程研究所 === 91 === The DiffServ-aware MPLS Traffic Engineering scheme offers an attractive way to ensure end-to-end QoS commitments for future mobile IP networks. Packets along the DiffServ network will be classified to different priority levels according to the traffic profiles. Afterwards, the Label Edge Router in the MPLS network will check the incoming packets, control the network resources, and perform the traffic engineering. This thesis proposes a two-layer hierarchical system with corresponding Edge Router Agents (ERAs). ERAs handle the localized mobility in the access network layer, and ERAs in the core network layer perform the Shortest Distance with Preemption Algorithm (SDPA) to deal with the resource management. The proposed scheme offers a scalable, multi-service solution with Quality of Service (QoS) guarantees for future IP wireless networks. The simulation results validate the better performance to higher-priority flows with higher throughput and lower transmission delay. The system utilization is maximized through the proposed TE-enabled network.
