Guaranteed QoS routing scheme in MPLS-wireless access networks

الملخص EN

With the increasing deployment of mobile network infrastructure and the emergency of real time applications, using Multi Protocol Label Switching (MPLS) capabilities is becoming more and more necessary to satisfy end user requirements in term of Quality of Services.

In this paper, we propose a new algorithm that routes efficiently Label Switched Paths (LSP) in mobile MPLS network.

The particularity of our work consists of integration both macro and micro mobility management in order to improve the overall performance of the system.

We propose first a fast handoff process, which reduces service disruption.

We present then new architecture which looks at avoiding triangle routing problem that MPLS inherits from Mobile IP.

Finally, we integrate route optimization process which computes efficiently the shortest path by compromising between several Traffic Engineering (TE) objectives, like bandwidth guarantees, load balancing, and minimizing path hop count.
