A novel model for inter-domain QoS management for real-time applications

The paper proposes a novel model for an inter-domain quality of service (QoS) management architecture consisting of a common open policy services (COPS) based policy control management system, a clearing-house (CH) acting as a policy architecture that regulates the resource allocations to different groups of traffic, an open settlement protocol (OSP) used to negotiate between CHs, and a differentiated service (DiffServ) network with dynamic advanced resource allocation.
