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.
