Introduction
Signalisation pour la QoS de bout en bout dans les réseaux NGN

The next generation of networks will see the convergence of the telephone network and the IP network into a single, unified network. One advantage of this convergence is the possibility of deploying new multimedia services, as well as integrating packet and circuit technologies in a solution that takes end-to-end QoS into account. Two signaling models are possible: path-coupled and path-decoupled (see § 2). QoS solutions will enable bandwidth to be shared efficiently between traditional best-effort applications and quality-assured services such as VoIP (voice over IP) or VoD (video on demand). To be guaranteed, the convergence solution must meet three criteria [1]...
