This work proposes an optimal quality level adaptation mechanism based on contracted service level agreement (SLAs) and defines an optimal service policy for a Voice over IP (VoIP) application provider over DiffServ/MPLS networks. A VoIP application provider between VoIP users and network service providers faces the challenge of SLA mapping to maximise its profit and satisfy users' requirements adapts the quality level of each active call to new network conditions well, and maximises the profit under the constraints on the contracted SLAs. The contributions would help application providers develop call admission control (CAC) schemes and proprietary service policies efficiently.
