MPLS based architecture for mobility and end-to-end QoS support in fourth generation mobile networks

Problem statement: Next-generation mobile networks are evolving towards network architectures relying entirely on IP. Approach: These networks had to be scalable in order to support future IP traffic, namely new multimedia services and real time applications, while providing an effective mobility management mechanism to cope with increasingly mobile users. In addition to global connectivity, next-generation mobile networks will have to offer quality of service guarantees such as assured bandwidth, low rate of packet loss, low delay and jitter. Results: In this study, we proposed an MPLS-based architecture for mobility management and end-to-end quality of service support in fourth-generation all-IP mobile networks (MAFI). Conclusion/Recommendations: Our scheme aimed to reduce handoff latency by implementing the fast handover technique and to increase the robustness and flexibility of the mobile system. The results obtained confirm the efficiency of MAFI when compared to FHMIPv6 and others schemes well-known in the literature.
