Study and proposal of a mapping between the classes of 3G services and DiffServ model for IP/MPLS transport network

The establishment of all-IP architecture is today, a major challenge to many telecommunications operators. This is a necessary passage towards the world of simplicity and convergence offered by new technologies and those to come. In this article, we show that the current evolution of communications networks tends towards the adoption of IP technology and QoS support from end to end. In this context, we demonstrate that IP/MPLS networks need to have a QoS architecture sufficiently mature to support the management of priority in terms of delay, jitter and loss rate required by the services. Thus, we propose a mapping between the classes of services 3G and the DiffServ model for transport IP/MPLS network, and prove the excellence of quality guaranteed network.
