A key challenge for Next Generation Networks (NGN) is providing support for the negotiation and dynamic adaptation of Quality of Service (QoS) parameters. In this paper we propose a novel QoS Matching and Optimization Function (Q-MOF) to be included along the signaling path with the purpose of providing advanced service-level QoS matching and optimization logic for multimedia services being delivered to heterogeneous end users and access networks. The Q-MOF is introduced in the NGN architecture as a generic functionality, allowing for it to be reused by services requiring advanced QoS support. We illustrate Q-MOF applicability in a case study involving an audio/video streaming session between two users. © 2009 Springer-Verlag Berlin Heidelberg.
