Next Generation Networks (NGN) will be based upon the “all IP ” paradigm. The IP protocol will glue multiple technologies, for both access and core network, in a common and scalable framework that will provide seamless communication mobility not only across those technologies, but also across different network operators. In this article we describe a framework for QoS support in such NGNs, where multi-interface terminals are given end-to-end QoS guarantees regardless of their point of attachment. The framework supports media independent handovers, triggered either by the user or by the network, to optimize network resources ’ distribution. The framework integrates layer two and layer three handovers by exploiting minimal additions to existing IETF and IEEE standards.
